&lt;hr /&gt;
&lt;div&gt;Cet article ne doit pas être considéré comme un remplacement d&#039;articles plus détaillés sur de meilleurs moyens de sécuriser son portefeuille, mais comme une liste de points clés dans la sécurité de votre portefeuille :&lt;br /&gt;
&lt;br /&gt;
* Vous devez crypter votre portefeuille.&lt;br /&gt;
* Vous devez faire une sauvegarde de votre portefeuille.&lt;br /&gt;
* Vous devez utiliser des portefeuilles recommandés de cette liste : https://bitcoin.org/fr/choisir-votre-porte-monnaie.&lt;br /&gt;
* Vous devez garder votre OS à jour et avoir un antivirus.&lt;br /&gt;
* Vous devez utiliser un portefeuille papier ou un portefeuille physique pour stocker de grosses sommes.&lt;br /&gt;
* Vous NE devez PAS sauvegarder votre portefeuille sur un service de stockage en ligne ( ex : Mega, Dropbox, Google Drive, etc... ).&lt;br /&gt;
* Vous NE devez PAS réutiliser des adresses publics plusieurs fois ( Ce conseil s&#039;applique pour les portefeuilles papier aussi ).&lt;br /&gt;
* Vous NE devez PAS générer une clé privée qui servira pour un portefeuille papier sur une machine connectée à Internet. Si c&#039;est pour un stockage hors-ligne, cela ne doit JAMAIS être fait sur une machine connectée à Internet.&lt;br /&gt;
Si pour n&#039;importe quelles raisons vous développez votre propre portefeuille, vous NE devez PAS rajouter d&#039;outils cryptographique par vous-même. Regardez cet exemple venant de Sony comme exemple de ce qui peut arriver de mal : http://www.exophase.com/20540/hackers-describe-ps3-security-as-epic-fail-gain-unrestricted-access/&lt;br /&gt;
&lt;br /&gt;
Pour plus de détails, merci de voir l&#039;article principal https://fr.bitcoin.it/wiki/S%C3%A9curiser_votre_portefeuille ou des articles connexes :&lt;br /&gt;

&lt;div&gt;==A propos de la page &amp;quot;Nous acceptons Bitcoin&amp;quot;==&lt;br /&gt;
Voici une liste des sites qui acceptent Bitcoin. Les nouveaux fournisseurs de services sont les bienvenus puisqu&#039;ils aident à établir la devise. Ne listez que les services qui sont présentement accessibles et qui acceptent les bitcoins. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;Note : Il existe une page dédiées aux [[Commerces_physiques|endroits physiques]] acceptant le Bitcoin.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Attention : Il est de votre responsabilité de vous assurer de la réputation des fournisseurs de services cités dans cette page. Le fait que ces sites apparaissent dans cette liste n&#039;est pas une garantie de qualité.&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;Note : Cette page est en cours de mise-à-jour. Elle était initialement une adaptation de la page équivalente en anglais et n&#039;est donc pas encore à jour.&#039;&#039;&lt;br /&gt;
===Convention de mise en page===&lt;br /&gt;
Si le service, le site ou le commerce est basé principalement en France ou est principalement destiné à un public francophone, merci d&#039;ajouter le drapeau français en fin de ligne à l&#039;aide du code suivant: &amp;lt;nowiki&amp;gt;[[Fichier:Drapeau_france.jpeg]]&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;nowiki&amp;gt;[http://www.example.com www.example.fr] Site basé en France. [[Fichier:Drapeau_france.jpeg]]&amp;lt;/nowiki&amp;gt; apparaîtra comme ceci: [http://www.example.com www.example.fr] Site basé en France. [[Fichier:Drapeau_france.jpeg]]&lt;br /&gt;
&lt;br /&gt;
Si le service, le site ou le commerce est correctement et presque entièrement traduit en français, merci d&#039;ajouter le mot &#039;&#039;&#039;français&#039;&#039;&#039; en gras dans la description (ex.: Site en &#039;&#039;&#039;français&#039;&#039;&#039;, traduit en &#039;&#039;&#039;français&#039;&#039;&#039;). Pour faire apparaître un mot en gras ajouter trois symboles &#039; avant et après le mot:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;nowiki&amp;gt;&#039;&#039;&#039;français&#039;&#039;&#039;&amp;lt;/nowiki&amp;gt; apparaîtra comme ceci: &#039;&#039;&#039;français&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Sans être particulièrement chauvin, je pense qu&#039;il serait souhaitable de mettre les services basés en France ou traduits en français en tête de liste, par ordre alphabétique.&lt;br /&gt;
&lt;br /&gt;
===Proposez un site, une adresse===&lt;br /&gt;

&lt;div&gt;[[File:FirstBitcoinBills.jpg|thumb|right|200px|Casascius tenant les premiers portefeuilles papier]]&lt;br /&gt;
&lt;br /&gt;
Dans un sens plus global, un &amp;quot;portefeuille papier&amp;quot; est un document contenant toutes les informations nécessaires pour générer n&#039;importe quel nombre de clé privée Bitcoin, formant un portefeuille de clés. Mais, les gens utilisent souvent ce terme pour n&#039;importe quelles façons de stocker ses bitcoins de manière hors-ligne sur un document physique. Cette seconde définitions inclus les codes récupérable ou des &amp;quot;clés papier&amp;quot;. Une clé papier est une clé unique écrite sur un morceau de papier qui est utilisé plusieurs fois comme un portefeuille ( Ceci est d&#039;ailleurs fortement [[address reuse|déconseiller]] ). Un code récupérable est une simple clé dont le but est d&#039;être remplis et utiliser qu&#039;une fois : C&#039;est souvent utiliser pour des cadeaux ou dans le but de créer des billes ou pièces Bitcoin physique.&lt;br /&gt;
&lt;br /&gt;
Stocker ses bitcoins sur un portefeuille papier n&#039;est pas sécuriser SI vous ne suivez pas toutes les mesures de sécurité à prendre pendant la création ( voir ci-dessous ).&lt;br /&gt;
&lt;br /&gt;
__TOC__&lt;br /&gt;
&lt;br /&gt;
==Cas d&#039;utilisation==&lt;br /&gt;
&lt;br /&gt;
===Pourboire et cadeaux===&lt;br /&gt;
&lt;br /&gt;
En créant une pair de clés, une peut stocker les bitcoins sur un support physique qui peut être donner comme pourboire ou cadeau.&lt;br /&gt;
Le destinataire charge la clé privée sur son portefeuille personnel.&lt;br /&gt;
&lt;br /&gt;
===Jetons physiques===&lt;br /&gt;
&lt;br /&gt;
Un fournisseur de confiance peut cacher la clé privée dans un token inviolable, et leur délivrer comme une forme de bitcoins.&lt;br /&gt;
Cela exige ceux qui l&#039;acceptent comme moyen de paiement de croire que lorsque le fournisseur a produit les jetons, ils les chargés avec la bonne quantité de bitcoins, et qu&#039;ils ont pas été altéré depuis.&lt;br /&gt;
Pour racheter la valeur de Bitcoin, le jeton doit être détruit pour accéder à la clé privée.&lt;br /&gt;
Souvent, une adresse Bitcoin est intégré sur le visible à l&#039;extérieur, mais il n&#039;y a aucune garantie (sans détruire le jeton) que cela correspond à la clé privée à l&#039;intérieur, ou, même si elle le fait, que la clé privée ne sont pas répliquées sur plusieurs jetons ou sauvé par le producteur.&lt;br /&gt;
&lt;br /&gt;
Un fournisseur de confiance peut cacher la clé privée dans un jeton inviolable, et le délivrer comme une forme de bitcoins.&lt;br /&gt;
Cela exige de ceux qui acceptent ces jetons comme moyen de paiement de faire confiance à la personne ou l&#039;entité qui les as produits, si ils les ont bien chargés avec le montant correct de bitcoins, et qu&#039;ils n&#039;ont pas été déplacer depuis.&lt;br /&gt;
Pour récupérer les bitcoins, le jeton doit être au préalable &amp;quot;détruit&amp;quot; pour pouvoir accéder à la clé privée.&lt;br /&gt;
Souvent, une adresse Bitcoin ( Une clé public ) est affiché sur l&#039;extérieur du jeton de manière visible pour prouver qu&#039;il y a bien des bitcoins sur celui-ci. Mais il n&#039;y a aucune garantie que cette adresse public Bitcoin qui est sur le jeton correspond à la clé privée qu&#039;il y a dans celui-ci tant que l&#039;on ne l&#039;a pas &amp;quot;détruit&amp;quot; pour récupérer la clé privée, et que, même si c&#039;est bien la bonne adresse public, il y a aucun moyen de vérifier si la clé privée n&#039;a pas été copier sur plusieurs autres jetons ou sauvegarder par le créateur des jetons.&lt;br /&gt;
&lt;br /&gt;
===Portefeuille===&lt;br /&gt;
&lt;br /&gt;
Proper paper wallets are often a very secure way of storing bitcoins, since they are not typically exposed to malware. They can also be easily stored securely in safes and safe deposit boxes. However, it may be more difficult to securely &amp;quot;backup&amp;quot; paper wallets, and due to the current sub-optimal software support, it may be easier to make a mistake that causes loss of bitcoins.&lt;br /&gt;
&lt;br /&gt;
Sometimes people try to use single keys as true bitcoin wallets. However [[address reuse]] is very bad for privacy and security. Because of this, one is forced to choose between hazardous options:&lt;br /&gt;
* &#039;&#039;&#039;Use the key only once to receive, and only once to send the full amount.&#039;&#039;&#039; This requires the user to know the full amount he wants to store in advance, and often leads to the next situation:&lt;br /&gt;
* &#039;&#039;&#039;Create multiple keys.&#039;&#039;&#039; By using more than one key, the user can receive more than once using a different address each time, including using new addresses for change. This is very complicated, and makes it easy to accidentally reuse addresses, produce the wrong change/fee combination, lose some keys, spend hours searching for the right key, etc. Not even skilled bitcoin experts are comfortable managing their own keys manually like this.&lt;br /&gt;
&lt;br /&gt;
Therefore, it is highly recommended that you use proper paper wallets which allow you to generate an infinite number of addresses from a single seed.&lt;br /&gt;
&lt;br /&gt;
==Encoding/formatting==&lt;br /&gt;
&lt;br /&gt;
[[File:BitcoinPaperWallet-sample.jpg|thumb|right|300px|Paper keypair with private key secured beneath folds]]&lt;br /&gt;
[[File:PaperWallets-offlineaddress-com.png|200px|thumb|right|Paper keypair]]&lt;br /&gt;
Proper, multi-key paper wallets usually take the form of a multi-word [[Deterministic wallet | HD wallet]] seed mnemonic. The list of several words corresponds to some binary data that is used to generate all of the addresses. Words are used to make it easier to avoid and correct errors. Trying to memorize an entire seed mnemonic is very difficult and is generally not recommended.&lt;br /&gt;
&lt;br /&gt;
A single key (for use in insecure single-key paper wallets or redeemable codes) can be represented in several formats, but typically the Wallet Import Format (WIF) is used, since keys represented that way are very short (51 characters) and thus easy to re-enter when importing or &amp;quot;sweeping&amp;quot; it for withdrawal.&lt;br /&gt;
&lt;br /&gt;
==Creation of a paper wallet==&lt;br /&gt;
&lt;br /&gt;
===Generation of secure keys===&lt;br /&gt;
&lt;br /&gt;
The private seed is used to prove your right to spend the bitcoins transferred to the paper wallet, and as such should be kept hidden and secret.&lt;br /&gt;
If the private seed on a paper wallet is exposed (for example in a photograph) then the wallet may be used by anyone who sees it.&lt;br /&gt;
To guard against accidental revelation, the private key displayed on the paper wallet may be encrypted or split into several different parts (for example using [https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing Shamir&#039;s secret sharing scheme]).&lt;br /&gt;
At the very least, the private key should be well hidden e.g. by folding the wallet in half and sealing it shut.&lt;br /&gt;
&lt;br /&gt;
Currently, at least [[Armory]] and [[Electrum]] support generating mnemonic codes for their wallets, which can be written down or printed to make a multi-key paper wallet.&lt;br /&gt;
&lt;br /&gt;
Several tools exist for producing single keys, including [[Bitcoin Address Utility]], [[vanitygen]], and [[Cwallet]]. Again, using single keys for anything except one-time &#039;&#039;transfers&#039;&#039; of bitcoins is strongly [[address reuse|discouraged]].&lt;br /&gt;
&lt;br /&gt;
===Web-based key generators===&lt;br /&gt;
&lt;br /&gt;
Some websites feature free open-source client-side keypair/wallet generators written in JavaScript.&lt;br /&gt;
Keypairs/wallets generated by JavaScript or using websites are inherently weak and insecure, and unless the code of the website is audited every time it is used, it may leak the generated keys back to the server—especially if un-audited Javascript is downloaded and run locally.&lt;br /&gt;
Even with careful code auditing, browser plugins or other websites may compromise the environment.&lt;br /&gt;
&lt;br /&gt;
===Recommendations===&lt;br /&gt;
* Disconnecting from the Internet guarantees that that the paper wallet generator is truly self-contained and isn&#039;t transmitting your keys online. &lt;br /&gt;
* Verifying the integrity of the code (and the trustworthiness of the author) is important to make sure a hacker hasn&#039;t modified the download so that it generates predictable seeds instead of truly random ones.&lt;br /&gt;
* Remember, spyware and viruses often attempt to monitor your computer activities so that their authors can steal from you. They are interested in passwords to online accounts, and anything of value. Bitcoin wallets are something of value that have already been targeted by malware. If your computer is infected with spyware or viruses - even if there are no symptoms, or your antivirus isn&#039;t reporting anything - then anything you type, view, or save on your computer, could potentially be stolen by someone remotely controlling your computer. Your private seed can then be intercepted while you enter it, so only enter a Bitcoin private seed into your computer when you are certain it is secure (such as a fresh boot of a LiveCD).&lt;br /&gt;
* The wallet should never be saved to a computer hard drive or sent via email or other network connections.  You should also never scan/type your key into your computer, except at the moment you are using it.&lt;br /&gt;
* If possible, the wallet should be kept hidden, for example by using BIP38 encryption (single keys only), and/or by folding the paper to hide the private key so that a photograph or photocopy of it will not reveal or replicate the private key.&lt;br /&gt;
* A web-based generator should not be used.&lt;br /&gt;
* A generator should use an appropriate source of random numbers (entropy).  This means that the generated keys aren&#039;t predictable.  If the addresses come from a predictable or partially-predictable patterns like pseudorandom numbers &amp;lt;ref&amp;gt;[https://en.wikipedia.org/wiki/Pseudorandomness#Cryptography Pseudorandomness] &#039;&#039; is not enough for strong cryptography&#039;&#039;&amp;lt;/ref&amp;gt;, someone else who can predict the pattern can steal the balance. Randomness should NEVER be human generated, as the human brain is incapable of secure entropy.&lt;br /&gt;
* Remember that unlike wallets (paper or otherwise), a single paper key is only good to receive a single payment, and must be redeemed in its entirety.&lt;br /&gt;
&lt;br /&gt;
===Printer Security===&lt;br /&gt;
&lt;br /&gt;
Some advanced printers have internal storage (even hard drives) that preserve copies of printouts. This is a risk if someone gets access to your printer, or if you dispose of your printer. There is also the possibility that a smart enough printer can be hacked. (Consider [http://en.wikipedia.org/wiki/Stuxnet StuxNet] which was able to rewrite the firmware of non-computer devices indirectly connected to the Internet) If this concerns you, use a &amp;quot;dumb&amp;quot; printer, and never let your printer have access to the Internet or to an Internet-connected computer.&lt;br /&gt;
&lt;br /&gt;
==Redeeming Keys and Withdrawing Funds==&lt;br /&gt;
&lt;br /&gt;
This section applies only to single-key paper &amp;quot;wallets&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Paper keys, when used as wallets, are very different from wallets such as Bitcoin Core in that there is only one address in a paper key rather than a hundred or more online keys that are managed with full software assistance from Bitcoin Core.&lt;br /&gt;
&lt;br /&gt;
There are various methods for copying the private key data to other wallets.&lt;br /&gt;
* bitcoind supports an &amp;quot;importprivkey&amp;quot; RPC method for this purpose.&lt;br /&gt;
* Bitcoin-Qt&#039;s debug console can also be used in a similar way (see also [[How to import private keys in Bitcoin Core 0.7+]]).&lt;br /&gt;
* [[BlockChain.info]] and [[Armory]] can also import them directly into wallets.&lt;br /&gt;
* [http://MyCelium.com/download Mycelium] is a Android mobile wallet with an easy to use &amp;quot;cold storage&amp;quot; spending function. It is also available via Android and iTunes playstore. The iTunes version may not yet support cold storage spending.&lt;br /&gt;
&lt;br /&gt;
Note that importing a private key that may be compromised can result in the entire wallet becoming insecure. For this reason, sweeping (or sending the entire amount to a fresh address) is generally recommended over plain importing.&lt;br /&gt;

&lt;br /&gt;
Dans un sens plus global, un &amp;quot;portefeuille papier&amp;quot; est un document contenant toutes les informations nécessaires pour générer n&#039;importe quel nombre de clé privée Bitcoin, formant un portefeuille de clés. Mais, les gens utilisent souvent ce terme pour n&#039;importe quelles façons de stocker ses bitcoins de manière hors-ligne sur un document physique. Cette seconde définitions inclus les codes récupérable ou des &amp;quot;clés papier&amp;quot;. Une clé papier est une clé unique écrite sur un morceau de papier qui est utilisé plusieurs fois comme un portefeuille ( Ceci est d&#039;ailleurs fortement [[address reuse|déconseiller]] ). Un code récupérable est une simple clé dont le but est d&#039;être remplis et utiliser qu&#039;une fois : C&#039;est souvent utiliser pour des cadeaux ou dans le but de créer des billes ou pièces Bitcoin physique.&lt;br /&gt;
&lt;br /&gt;
Stocker ses bitcoins sur un portefeuille papier n&#039;est pas sécuriser SI vous ne suivez pas toutes les mesures de sécurité à prendre pendant la création ( voir ci-dessous ).&lt;br /&gt;
&lt;br /&gt;
__TOC__&lt;br /&gt;
&lt;br /&gt;
==Use cases==&lt;br /&gt;
&lt;br /&gt;
===Tips and gifts===&lt;br /&gt;
&lt;br /&gt;
By creating a keypair, one can store bitcoins on a physical medium to be left as a tip or a gift.&lt;br /&gt;
The recipient then sweeps the private key to their own wallet.&lt;br /&gt;
&lt;br /&gt;
===Physical tokens===&lt;br /&gt;
&lt;br /&gt;
A trusted provider can hide the private key inside a tamper-resistant token, and issue them as a form of bitcoins.&lt;br /&gt;
This requires those who accept it as payment to trust that when the provider produced the tokens, they loaded them with the correct amount of bitcoins, and that they have not been tampered with since then.&lt;br /&gt;
To redeem the bitcoin value, the token must be destroyed to access the private key.&lt;br /&gt;
Often a bitcoin address is embedded on the outside visible, but there is no guarantee (without destroying the token) that this matches the private key inside, or, even if it does, that the private key is not replicated on multiple tokens or saved by the producer.&lt;br /&gt;
&lt;br /&gt;
===Portefeuille===&lt;br /&gt;
&lt;br /&gt;
Proper paper wallets are often a very secure way of storing bitcoins, since they are not typically exposed to malware. They can also be easily stored securely in safes and safe deposit boxes. However, it may be more difficult to securely &amp;quot;backup&amp;quot; paper wallets, and due to the current sub-optimal software support, it may be easier to make a mistake that causes loss of bitcoins.&lt;br /&gt;
&lt;br /&gt;
Sometimes people try to use single keys as true bitcoin wallets. However [[address reuse]] is very bad for privacy and security. Because of this, one is forced to choose between hazardous options:&lt;br /&gt;
* &#039;&#039;&#039;Use the key only once to receive, and only once to send the full amount.&#039;&#039;&#039; This requires the user to know the full amount he wants to store in advance, and often leads to the next situation:&lt;br /&gt;
* &#039;&#039;&#039;Create multiple keys.&#039;&#039;&#039; By using more than one key, the user can receive more than once using a different address each time, including using new addresses for change. This is very complicated, and makes it easy to accidentally reuse addresses, produce the wrong change/fee combination, lose some keys, spend hours searching for the right key, etc. Not even skilled bitcoin experts are comfortable managing their own keys manually like this.&lt;br /&gt;
&lt;br /&gt;
Therefore, it is highly recommended that you use proper paper wallets which allow you to generate an infinite number of addresses from a single seed.&lt;br /&gt;
&lt;br /&gt;
==Encoding/formatting==&lt;br /&gt;
&lt;br /&gt;
[[File:BitcoinPaperWallet-sample.jpg|thumb|right|300px|Paper keypair with private key secured beneath folds]]&lt;br /&gt;
[[File:PaperWallets-offlineaddress-com.png|200px|thumb|right|Paper keypair]]&lt;br /&gt;
Proper, multi-key paper wallets usually take the form of a multi-word [[Deterministic wallet | HD wallet]] seed mnemonic. The list of several words corresponds to some binary data that is used to generate all of the addresses. Words are used to make it easier to avoid and correct errors. Trying to memorize an entire seed mnemonic is very difficult and is generally not recommended.&lt;br /&gt;
&lt;br /&gt;
A single key (for use in insecure single-key paper wallets or redeemable codes) can be represented in several formats, but typically the Wallet Import Format (WIF) is used, since keys represented that way are very short (51 characters) and thus easy to re-enter when importing or &amp;quot;sweeping&amp;quot; it for withdrawal.&lt;br /&gt;
&lt;br /&gt;
==Creation of a paper wallet==&lt;br /&gt;
&lt;br /&gt;
===Generation of secure keys===&lt;br /&gt;
&lt;br /&gt;
The private seed is used to prove your right to spend the bitcoins transferred to the paper wallet, and as such should be kept hidden and secret.&lt;br /&gt;
If the private seed on a paper wallet is exposed (for example in a photograph) then the wallet may be used by anyone who sees it.&lt;br /&gt;
To guard against accidental revelation, the private key displayed on the paper wallet may be encrypted or split into several different parts (for example using [https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing Shamir&#039;s secret sharing scheme]).&lt;br /&gt;
At the very least, the private key should be well hidden e.g. by folding the wallet in half and sealing it shut.&lt;br /&gt;
&lt;br /&gt;
Currently, at least [[Armory]] and [[Electrum]] support generating mnemonic codes for their wallets, which can be written down or printed to make a multi-key paper wallet.&lt;br /&gt;
&lt;br /&gt;
Several tools exist for producing single keys, including [[Bitcoin Address Utility]], [[vanitygen]], and [[Cwallet]]. Again, using single keys for anything except one-time &#039;&#039;transfers&#039;&#039; of bitcoins is strongly [[address reuse|discouraged]].&lt;br /&gt;
&lt;br /&gt;
===Web-based key generators===&lt;br /&gt;
&lt;br /&gt;
Some websites feature free open-source client-side keypair/wallet generators written in JavaScript.&lt;br /&gt;
Keypairs/wallets generated by JavaScript or using websites are inherently weak and insecure, and unless the code of the website is audited every time it is used, it may leak the generated keys back to the server—especially if un-audited Javascript is downloaded and run locally.&lt;br /&gt;
Even with careful code auditing, browser plugins or other websites may compromise the environment.&lt;br /&gt;
&lt;br /&gt;
===Recommendations===&lt;br /&gt;
* Disconnecting from the Internet guarantees that that the paper wallet generator is truly self-contained and isn&#039;t transmitting your keys online. &lt;br /&gt;
* Verifying the integrity of the code (and the trustworthiness of the author) is important to make sure a hacker hasn&#039;t modified the download so that it generates predictable seeds instead of truly random ones.&lt;br /&gt;

* The wallet should never be saved to a computer hard drive or sent via email or other network connections.  You should also never scan/type your key into your computer, except at the moment you are using it.&lt;br /&gt;
* If possible, the wallet should be kept hidden, for example by using BIP38 encryption (single keys only), and/or by folding the paper to hide the private key so that a photograph or photocopy of it will not reveal or replicate the private key.&lt;br /&gt;
* A web-based generator should not be used.&lt;br /&gt;
* A generator should use an appropriate source of random numbers (entropy).  This means that the generated keys aren&#039;t predictable.  If the addresses come from a predictable or partially-predictable patterns like pseudorandom numbers &amp;lt;ref&amp;gt;[https://en.wikipedia.org/wiki/Pseudorandomness#Cryptography Pseudorandomness] &#039;&#039; is not enough for strong cryptography&#039;&#039;&amp;lt;/ref&amp;gt;, someone else who can predict the pattern can steal the balance. Randomness should NEVER be human generated, as the human brain is incapable of secure entropy.&lt;br /&gt;
* Remember that unlike wallets (paper or otherwise), a single paper key is only good to receive a single payment, and must be redeemed in its entirety.&lt;br /&gt;
&lt;br /&gt;
===Printer Security===&lt;br /&gt;
&lt;br /&gt;
Some advanced printers have internal storage (even hard drives) that preserve copies of printouts. This is a risk if someone gets access to your printer, or if you dispose of your printer. There is also the possibility that a smart enough printer can be hacked. (Consider [http://en.wikipedia.org/wiki/Stuxnet StuxNet] which was able to rewrite the firmware of non-computer devices indirectly connected to the Internet) If this concerns you, use a &amp;quot;dumb&amp;quot; printer, and never let your printer have access to the Internet or to an Internet-connected computer.&lt;br /&gt;
&lt;br /&gt;
==Redeeming Keys and Withdrawing Funds==&lt;br /&gt;
&lt;br /&gt;
This section applies only to single-key paper &amp;quot;wallets&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Paper keys, when used as wallets, are very different from wallets such as Bitcoin Core in that there is only one address in a paper key rather than a hundred or more online keys that are managed with full software assistance from Bitcoin Core.&lt;br /&gt;
&lt;br /&gt;
There are various methods for copying the private key data to other wallets.&lt;br /&gt;
* bitcoind supports an &amp;quot;importprivkey&amp;quot; RPC method for this purpose.&lt;br /&gt;
* Bitcoin-Qt&#039;s debug console can also be used in a similar way (see also [[How to import private keys in Bitcoin Core 0.7+]]).&lt;br /&gt;
* [[BlockChain.info]] and [[Armory]] can also import them directly into wallets.&lt;br /&gt;
* [http://MyCelium.com/download Mycelium] is a Android mobile wallet with an easy to use &amp;quot;cold storage&amp;quot; spending function. It is also available via Android and iTunes playstore. The iTunes version may not yet support cold storage spending.&lt;br /&gt;
&lt;br /&gt;
Note that importing a private key that may be compromised can result in the entire wallet becoming insecure. For this reason, sweeping (or sending the entire amount to a fresh address) is generally recommended over plain importing.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;Cet article ne doit pas être considérer comme un remplacement d&#039;articles plus détaillés sur des meilleurs moyens de sécuriser son portefeuille, mais comme une liste de point clé dans la sécurité de votre portefeuille :&lt;br /&gt;
&lt;br /&gt;
* Vous devez crypter votre portefeuille.&lt;br /&gt;
* Vous devez faire une sauvegarde de votre portefeuille.&lt;br /&gt;
* Vous devez utiliser des portefeuilles recommandés de cette liste : https://bitcoin.org/fr/choisir-votre-porte-monnaie.&lt;br /&gt;
* Vous devez garder votre OS à jour et avoir un anti-virus.&lt;br /&gt;
* Vous devez utiliser un portefeuille papier ou un portefeuille physique pour stocker de grosses sommes.&lt;br /&gt;
* Vous NE devez PAS sauvegarder votre portefeuille dans un stockage en ligne ( Mega, Dropbox, Google Drive, etc... ).&lt;br /&gt;
* Vous NE devez PAS réutiliser des adresses ( Ce conseil s&#039;applique pour les portefeuilles papier aussi ).&lt;br /&gt;
* Vous NE devez PAS générer une clé privée qui servira pour un portefeuille papier sur une machine connectée à Internet. Si c&#039;est pour un stockage hors-ligne, cela ne doit JAMAIS être fait sur une machine connectée à Internet.&lt;br /&gt;
Si pour n&#039;importe quelles raisons vous développez votre propre portefeuille, vous NE devez PAS rajouter des outils cryptographique par vous-même. Regardez cet exemple venant de Sony comme exemple de ce qui peut arriver de mal : http://www.exophase.com/20540/hackers-describe-ps3-security-as-epic-fail-gain-unrestricted-access/&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;Éclairons quelques points communéments incompris de Bitcoin.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin est comme toutes les autres monnaies virtuelles; Rien de nouveau ==&lt;br /&gt;
&lt;br /&gt;
Presque toutes les autres monnaies digitales ont un contrôle centralisé. Cela signifie que :&lt;br /&gt;
* Elles peuvent être émises sur la simple décision de ceux qui la contrôle&lt;br /&gt;
* Elle peut être détruite en attaquant le point central de contrôle&lt;br /&gt;
* Des règles arbitraires peuvent être imposées aux utilisateurs par les contrôleurs&lt;br /&gt;
&lt;br /&gt;
En étant décentralisé, Bitcoin résout tous ces problèmes.&lt;br /&gt;
&lt;br /&gt;
== Bitcoins ne résout aucun problème que les monnaies locales et/ou l&#039;or ne résolve(nt) ==&lt;br /&gt;
&lt;br /&gt;
A la différence de l&#039;or, les bitcoins sont:&lt;br /&gt;
* Facile à transférer&lt;br /&gt;
* Facile à sécuriser&lt;br /&gt;
* Facile à vérifier&lt;br /&gt;
* Facile à décomposer (granulate)&lt;br /&gt;
&lt;br /&gt;
A la différence des monnaies locales, les bitcoins sont:&lt;br /&gt;
* A l&#039;[[Emission_Contrôlée_Monnaie|émission]] limitée et prédite &lt;br /&gt;
* Pas contrôlé par une autorité centrale (tel que [http://en.wikipedia.org/wiki/Federal_Reserve la Réserve Fédérale des Etats-Unis])&lt;br /&gt;
* Pas fondés sur une dette&lt;br /&gt;
&lt;br /&gt;
A la différence des systèmes de monnaies électroniques étatiques, les bitcoins sont:&lt;br /&gt;
* Potentiellement anonyme&lt;br /&gt;
* Sans risque de gel du compte&lt;br /&gt;
* Facile à transférer&lt;br /&gt;
* Moins cher à utiliser en transfert&lt;br /&gt;
&lt;br /&gt;
== Bitcoin est fondé sur de la puissance de calcul ==&lt;br /&gt;
&lt;br /&gt;
Il est incorrect de dire que Bitcoin est &amp;quot;fondé sur&amp;quot; la puissance de calcul. Une monnaie &amp;quot;fondée&amp;quot; signifie qu&#039;elle est liée à quelque chose d&#039;autre via une partie centrale, à un taux de change, alors que vous ne pouvez pas échanger des bitcoins contre la puissance de calcul qui a été utilisée pour les créer. En ce sens, Bitcoin n&#039;est pas fondé sur quoi que ce soit. Bitcoin est une devise de son propre droit. De même que l&#039;or n&#039;est pas fondé sur quoi que ce soit, il en va de même de Bitcoin. &lt;br /&gt;
&lt;br /&gt;
La monnaie Bitcoin est &#039;&#039;créée&#039;&#039; par de la puissance de calcul, et l&#039;intégrité de la chaine de blocks est &#039;&#039;protégée&#039;&#039; par l&#039;existence d&#039;un réseau de puissants noeuds pour prévenir des  [[Weaknesses#Attacker_has_a_lot_of_computing_power|attaques]].&lt;br /&gt;
&lt;br /&gt;
== Bitcoins sont sans valeurs car ils ne sont fondés sur rien ==&lt;br /&gt;
&lt;br /&gt;
Certains argumentent que l&#039;or n&#039;est fondé sur rien d&#039;autre. Bitcoins ont des propriétés issues de la conception de son système que leur permet d&#039;apporter une valeur subjective à leurs propriétaires. Cette valeur est démontrée lorsque des personnes échangent librement en bitcoins. Merci de vous référer à [http://en.wikipedia.org/wiki/Subjective_theory_of_value Subjective Theory of Value].&lt;br /&gt;
&lt;br /&gt;
A voir également : le mythe &amp;quot;[[#Bitcoin_is_backed_by_processing_power|Bitcoin is backed by processing power]]&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
== La valeur des bitcoins est fondé sur la quantité d&#039;électricité et de traitement qu&#039;il faut pour les miner ==&lt;br /&gt;
&lt;br /&gt;
This statement is an attempt to apply to Bitcoin the [http://en.wikipedia.org/wiki/Labor_theory_of_value labor theory of value], which is generally accepted as false. Just because something takes X resources to create does not mean that the resulting product will be worth X. It can be worth more, or less, depending on the utility thereof to its users.&lt;br /&gt;
&lt;br /&gt;
In fact the causality is the reverse of that (this applies to the labor theory of value in general). The cost to mine bitcoins is based on how much they are worth. If bitcoins go up in value, more people will mine (because [[Mining|mining]] is profitable), thus [[difficulty]] will go up, thus the cost of mining will go up. The inverse happens if bitcoins go down in value. These effects balance out to cause mining to always cost an amount proportional to the value of bitcoins it produces&amp;lt;ref&amp;gt;[https://www.bitcoinmining.com Bitcoin Mining]&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
== Les Bitcoins n&#039;ont pas de valeur intrinsèque (à la différence d&#039;autres choses) ==&lt;br /&gt;
&lt;br /&gt;
C&#039;est simplement faux. Chaque bitcoin accorde à son propriétaire la capacité d&#039;intégrer un grand nombre de petits messages de transactions dans un entrepôt de données distribuée, mondiale, horodatée, nommée la blockchain bitcoin. Il n&#039;existe pas d&#039;entrepôt similaire qui soit autant distribué. There is a tradeoff between the exact number of messages and how quickly they can be embedded. But as of December 2013, it&#039;s fair to say that one bitcoin allows around 1000 such messages to be embedded, each within about 10 minutes of being sent, since a fee of 0.001 BTC is enough to get transactions confirmed quickly. This message embedding certainly has intrinsic value since it can be used to prove ownership of a document at a certain time, by including a one-way hash of that document in a transaction. Considering that electronic notarization services charge something like $10/document, this would give an intrinsic value of around $10,000 per bitcoin.&lt;br /&gt;
&lt;br /&gt;
While some other tangible commodities do have intrinsic value, that value is generally much less than its trading price. Consider for example that gold, if it were not used as an inflation-proof store of value, but rather only for its industrial uses, would certainly not be worth what it is today, since the industrial requirements for gold are far smaller than the available supply thereof.&lt;br /&gt;
&lt;br /&gt;
In any event, while historically intrinsic value, as well as other attributes like divisibility, fungibility, scarcity, durability, helped establish certain commodities as mediums of exchange, it is certainly not a prerequisite. While bitcoins are accused of lacking &#039;intrinsic value&#039; in this sense, they make up for it in spades by possessing the other qualities necessary to make it a good medium of exchange, equal to or better than [http://en.wikipedia.org/wiki/Commodity_money commodity money].&lt;br /&gt;
&lt;br /&gt;
Another way to think about this is to consider the value of bitcoin the global network, rather than each bitcoin in isolation. The value of an individual telephone is derived from the network it is connected to. If there was no phone network, a telephone would be useless. Similarly the value of an individual bitcoin derives from the global network of bitcoin-enabled merchants, exchanges, wallets, etc... Just like a phone is necessary to transmit vocal information through the network, a bitcoin is necessary to transmit economic information through the network.&lt;br /&gt;
&lt;br /&gt;
Value is ultimately determined by what people are willing to trade for - by supply and demand.&lt;br /&gt;
&lt;br /&gt;
== Bitcoins est illegal car il n&#039;a pas cours légal ==&lt;br /&gt;
En mars 2013, the U.S. [http://en.wikipedia.org/wiki/Financial_Crimes_Enforcement_Network Financial Crimes Enforcement Network] issues a new set of guidelines on &amp;quot;de-centralized virtual currency&amp;quot;, clearly targeting Bitcoin. Under the new guidelines, &amp;quot;a user of virtual currency is not a Money Services Businesses (MSB) under FinCEN&#039;s regulations and therefore is not subject to MSB registration, reporting, and record keeping regulations.&amp;quot; &amp;lt;ref&amp;gt;[http://arstechnica.com/tech-policy/2013/03/us-regulator-bitcoin-exchanges-must-comply-with-money-laundering-laws/ US regulator: Bitcoin exchanges must comply with money-laundering laws | Ars Technica]&amp;lt;/ref&amp;gt; [[Mining|Miners]], when mining bitcoins for their own personal use, aren&#039;t required to register as a MSB or Money Transmitter. &amp;lt;ref&amp;gt;[http://fincen.gov/news_room/rp/rulings/html/FIN-2014-R001.html Application of FinCEN’s Regulations to Virtual Currency Mining Operations | Fincen]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In general, there are a [http://en.wikipedia.org/wiki/Local_currency number of currencies] in existence that are not official government-backed currencies. A currency is, after all, nothing more than a convenient unit of account. While national laws may vary from country to country, and you should certainly check the laws of your jurisdiction, in general trading in any commodity, including digital currency like Bitcoin, [http://en.wikipedia.org/wiki/BerkShares BerkShares], game currencies like WoW gold, or Linden dollars, is not illegal.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin est une forme de terrorisme domestique car il porte préjudice à la stabilité économique des USA et sa monnaie ==&lt;br /&gt;
&lt;br /&gt;
D&#039;après la [http://en.wikipedia.org/wiki/Definitions_of_terrorism#définition du terrorisme aux Etats-Unis d&#039;Amérique], il faut qu&#039;une activité soit violente pour qu&#039;elle puisse être légalement considérée comme potentiellement terroriste. Les remarques récentes off-the-cuff de politiciens n&#039;ont aucun fondement légal ou factuel.&lt;br /&gt;
&lt;br /&gt;
De plus, Bitcoin n&#039;est pas domestique aux USA ou à tout autre pays. Il s&#039;agit d&#039;une communauté mondiale, comme le montre la [https://bitcointalk.org/?topic=2346.0 carte des noeuds Bitcoin].&lt;br /&gt;
&lt;br /&gt;
== Bitcoin va uniquement permettre l&#039;évasion fiscale, qui va entrainé le probable effondrement de la civilisation ==&lt;br /&gt;
&lt;br /&gt;
Cash transactions hold the same level of anonymity but are still taxed successfully. It is up to you to follow the applicable state laws in your home country, or face the consequences.&lt;br /&gt;
&lt;br /&gt;
While it may be easy to transfer bitcoins anonymously, &#039;&#039;spending&#039;&#039; them anonymously on tangibles is just as hard as spending any other kind of money anonymously.  Tax evaders are often caught because their lifestyle and assets are inconsistent with their reported income, and not necessarily because government is able to follow their money.&lt;br /&gt;
&lt;br /&gt;
== Bitcoins peut être imprimé par n&#039;importe qui et n&#039;a donc aucune valeur ==&lt;br /&gt;
&lt;br /&gt;
Bitcoins n&#039;est pas imprimé. Instead, [[Blocks]] are computed by miners and for their efforts they are awarded a specific amount of bitcoins and transaction fees paid by others. See [[Mining]] for more information on how this process works.&lt;br /&gt;
&lt;br /&gt;
== Les Bitcoins n&#039;ont aucune valeur car ils sont fondés sur des cryptographies non prouvées ==&lt;br /&gt;
&lt;br /&gt;
SHA256 and [[ECDSA]] which are used in Bitcoin are well-known industry standard algorithms. SHA256 is endorsed and used by the US Government and is standardized (FIPS180-3 Secure Hash Standard). If you believe that these algorithms are untrustworthy then you should not trust Bitcoin, credit card transactions or any type of electronic bank transfer. Bitcoin has a sound basis in well understood cryptography.&lt;br /&gt;
&lt;br /&gt;
== Les premiers utilisateurs sont outrageusement récompensés ==&lt;br /&gt;
&lt;br /&gt;
Early adopters are rewarded for taking the higher risk with their time and money. The capital invested in bitcoin at each stage of its life invigorated the community and helped the currency to reach subsequent milestones. Arguing that early adopters do not deserve to profit from this is akin to saying that early investors in a company, or people who buy stock at a company IPO (Initial Public Offering), are unfairly rewarded.&lt;br /&gt;
&lt;br /&gt;
This argument also depends on bitcoin early adopters using bitcoins to store rather than transfer value. The daily trade on the exchanges (as of Jan 2012) indicates that smaller transactions are becoming the norm, indicating trade rather than investment. In more pragmatic terms, &amp;quot;fairness&amp;quot; is an arbitrary concept that is improbable to be agreed upon by a large population. Establishing &amp;quot;fairness&amp;quot; is no goal of Bitcoin, as this would be impossible.&lt;br /&gt;
&lt;br /&gt;
Looking forwards, considering the amount of publicity bitcoin received as of April 2013, there can be no reasonable grounds for complaint for people who did not invest at that time, and then see the value (possibly) rising drastically higher.&lt;br /&gt;
&lt;br /&gt;
By starting to mine or acquire bitcoins today, you too can become an early adopter.&lt;br /&gt;
&lt;br /&gt;
== 21 millions de bitcoin n&#039;est pas suffisant. Bitcoin ne pourra pas grandir ==&lt;br /&gt;
&lt;br /&gt;
1 bitcoin est divisible jusqu&#039;à 8 chiffres après la virgule (8 décimales). Il a aura exactement 2,099,999,997,690,000 (just over 2 quadrillion) unités minimales dans le système  bitcoin.&lt;br /&gt;
La valeur d&#039;&amp;quot;1 BTC&amp;quot; représente celle de 100,000,000 unité minimale, nommé Satoshi. Autrement dit, chaque bitcoin en 10&amp;lt;sup&amp;gt;8&amp;lt;/sup&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Pendant que la valeur d&#039;1 Bitcoin augmente pour ne plus être utilisable pour les transactions de la vie courante, les utilisateurs feront des transactions avec des unités plus petites [[Units|units]], tel que les milli-bitcoins (mBTC) or les micro-bitcoins (μBTC).&lt;br /&gt;
&lt;br /&gt;
== Les bitcoins sont stockés dans des fichiers. Il suffit de copier les fichiers pour avoir plus de bitcoins ! ==&lt;br /&gt;
&lt;br /&gt;
Non, votre porte-feuille contient une clé secrète, vous donnant le droit d&#039;utiliser vos bitcoins.&lt;br /&gt;
&lt;br /&gt;
Copier le fichier, c&#039;est donc faire une copie de la clé vous permettant d&#039;accéder à votre coffre. Cela ne double pas le montant qu&#039;il contient.&lt;br /&gt;
&lt;br /&gt;
== L&#039;argent détruit ne peut pas être remplacé et c&#039;est mal ==&lt;br /&gt;
&lt;br /&gt;
Les bitcoins sont divisibles jusqu&#039;à 0.00000001, donc, s&#039;il y a moins d&#039;argent restant, cela n&#039;est pas un problème pour la monnaie en soit. Si vous perdez vos bitcoins, l&#039;ensemble des autres bitcoins vont légèrement augmenter de valeur. C&#039;est, en quelque sorte, un don à l&#039;ensemble des autres utilisateurs de bitcoin.&lt;br /&gt;
&lt;br /&gt;
Une question comparable est : Pourquoi ne remplace-t-on pas automatiquement les bitcoins perdus? La réponse est qu&#039;il est impossible de différencier les bitcoins &amp;quot;perdus&amp;quot; de ceux qui sont simplement inutilisés dans un porte-feuille.&lt;br /&gt;
&lt;br /&gt;
== C&#039;est une pyramide de Ponzi géante ==&lt;br /&gt;
Dans une [[Wikipedia:Ponzi_scheme|pyramide de Ponzi]], les fondateurs persuadent des investisseurs qu&#039;ils feront des bénéfices. Bitcoin ne fait pas ce type de garantie. Il n&#039;y a pas d&#039;entité centrale, mais uniquement des individus qui construisent une économie.&lt;br /&gt;
&lt;br /&gt;
Une chaine de Ponzi est a zero sum game. Dans une chaine de Ponzi, les premiers adopteurs can only profit at the expense of late adopters, and the late adopters always lose. Bitcoin can have a win-win outcome. Earlier adopters profit from the rise in value as Bitcoin becomes better understood and in turn demanded by the public at large. All adopters benefit from the usefulness of a reliable and widely-accepted decentralized peer-to-peer currency.&amp;lt;ref name=Jeff_Tucker&amp;gt;cf. {{cite news | author-link = Wikipedia:Jeffrey_Tucker | url = http://libertarianstandard.com/2013/12/01/ponzi-logic-debunking-gary-north/ | title = Ponzi Logic: Debunking Gary North | last = Tucker | first = Jeffrey | date = 1 December 2013 | work = The Libertarian Standard | accessdate = 2015-04-11}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Il est également important de noter que [[Satoshi Nakamoto]], le créateur de bitcoin, n&#039;a jamais dépensé de bitcoin (other than giving them away when they were worthless) ce qui est vérifiable dans la blockchain.&lt;br /&gt;
&lt;br /&gt;
== Quantité limité de bitcoin + Perte de bitcoin =&amp;gt; Spirale déflationniste ==&lt;br /&gt;
As deflationary forces may apply, economic factors such as hoarding are offset by human factors that may lessen the chances that a [[Deflationary spiral]] will occur.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin can&#039;t work because there is no way to control inflation ==&lt;br /&gt;
&lt;br /&gt;
Inflation is simply a rise of prices over time, which is generally the result of the devaluing of a currency. This is a function of supply and demand. Given the fact that the supply of bitcoins is fixed at a certain amount, unlike fiat money, the only way for inflation to get out of control is for demand to disappear. Temporary inflation is possible with a rapid adoption of Fractional Reserve Banking but will stabilize once a substantial number of the 21 million &amp;quot;hard&amp;quot; bitcoins are stored as reserves by banks.&lt;br /&gt;
&lt;br /&gt;
Given the fact that Bitcoin is a distributed system of currency, if demand were to decrease to almost nothing, the currency would be doomed anyway.&lt;br /&gt;
&lt;br /&gt;
The key point here is that Bitcoin as a currency can&#039;t be inflated by any single person or entity, like a government, as there&#039;s no way to increase supply past a certain amount.&lt;br /&gt;
&lt;br /&gt;
Indeed, the most likely scenario, as Bitcoin becomes more popular and demand increases, is for the currency to increase in value, or deflate, until demand stabilizes.&lt;br /&gt;
&lt;br /&gt;
== The Bitcoin community consists of anarchist/conspiracy theorist/gold standard &#039;weenies&#039; ==&lt;br /&gt;
&lt;br /&gt;
The members of the community vary in their ideological stances. While it may have been started by ideological enthusiasts, Bitcoin now speaks to a large number of regular pragmatic folk, who simply see its potential for reducing the costs and friction of global e-commerce.&lt;br /&gt;
&lt;br /&gt;
== Toute personne avec assez de puissance de calcul peut prendre le contrôle du réseau ==&lt;br /&gt;
&lt;br /&gt;
C&#039;est confirmé. Voir [https://en.bitcoin.it/wiki/Weaknesses].&lt;br /&gt;
&lt;br /&gt;
Il est dit que plus le réseau grandit, plus il devient difficile pour une seule entité à le faire. La puissance de calcul du réseau Bitcoin est déjà très en avance sur celle des plus rapides super-ordinateurs du monde, tous réunis.&lt;br /&gt;
&lt;br /&gt;
Toutefois, ce que peut faire un attaquant une fois le réseau sous son contrôle est assez limité. En aucun cas, un attaquant pourrait créer de faux bitcoins, des fausses transactions, ou de prendre des bitcoins de quelqu&#039;un d&#039;autre. Les capacités d&#039;un attaquant sont limitées à récupérer ses propres bitcoins qu&#039;il a dépensé tout récemment, et d&#039;empêcher d&#039;autres personnes à recevoir leurs confirmations. Une telle attaque serait très coûteuse en terme de ressources, et pour les maigres avantages. Il y a peu d&#039;incitation économique rationnelle se lancer dans une telle attaque.&lt;br /&gt;
&lt;br /&gt;
En outre, ce scénario d&#039;attaque ne serait possible qu&#039;aussi longtemps que l&#039;attaque dure. Dès qu&#039;elle cesse, le réseau reprend son fonctionnement normal.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin violates governmental regulations ==&lt;br /&gt;
&lt;br /&gt;
There is no known governmental regulation which disallows the use of Bitcoin.&lt;br /&gt;
&lt;br /&gt;
See also: the &amp;quot;[[#Bitcoins_are_illegal_because_they.27re_not_legal_tender|Bitcoins are illegal because they&#039;re not legal tender]]&amp;quot; myth.&lt;br /&gt;
&lt;br /&gt;
== Fractional reserve banking is not possible ==&lt;br /&gt;
&lt;br /&gt;
It is possible. See the main article, [[Fractional Reserve Banking and Bitcoin]]&lt;br /&gt;
&lt;br /&gt;
== After 21 million coins are mined, no one will generate new blocks ==&lt;br /&gt;
&lt;br /&gt;
When operating costs can&#039;t be covered by the block creation bounty, which will happen some time before the total amount of BTC is reached, miners will earn some profit from [[transaction fees]].  However unlike the block reward, there is [http://bitcoin.stackexchange.com/questions/876/how-much-will-transaction-fees-eventually-be/895#895 no coupling between transaction fees and the need for security], so there is less of a guarantee that the amount of [[Mining|mining]] being performed will be sufficient to maintain the network&#039;s security.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin has no built-in chargeback mechanism, and this isn&#039;t good ==&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Why some people think this is bad&#039;&#039;&#039;: Chargebacks are useful for limiting fraud. The person handling your money has a responsibility to prevent fraud. If you buy something on eBay and the seller never ships it, PayPal takes funds from the seller&#039;s account and gives you back the money. This strengthens the eBay economy, because people recognize that their risk is limited and are more willing to purchase items from risky sellers.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Why it&#039;s actually a good thing&#039;&#039;&#039;: Bitcoin is designed such that your money is yours and yours alone. Allowing chargebacks implies that it is possible for another entity to take your money from you. You can have either total ownership rights of your money, or fraud protection, but not both.  That said, nothing inherent in the dollar or euro or any other currency is necessary for chargebacks to be possible, and likewise, nothing prevents the creation of PayPal-like services denominated in Bitcoin that provide chargebacks or fraud protection.&lt;br /&gt;
&lt;br /&gt;
The statement &amp;quot;The person handling your money has a responsibility to prevent fraud&amp;quot; is still true; the power has been shifted into your own hands. Fraud will always exist. It&#039;s up to you to only send bitcoins to trusted entities. It is possible to trust an online identity without ever knowing their physical identity; see the [http://wiki.bitcoin-otc.com/wiki/OTC_Rating_System OTC Web of Trust].&lt;br /&gt;
&lt;br /&gt;
== Quantum computers would break Bitcoin&#039;s security ==&lt;br /&gt;
&lt;br /&gt;
While ECDSA is indeed not secure under quantum computing, quantum computers don&#039;t yet exist and probably won&#039;t for a while.&lt;br /&gt;
The DWAVE system often written about in the press is, even if all their claims are true, not a quantum computer of a kind that could be used for cryptography.&lt;br /&gt;
Bitcoin&#039;s security, when used properly with a new address on each transaction, depends on more than just ECDSA: Cryptographic hashes are much stronger than ECDSA under QC.&lt;br /&gt;
Bitcoin&#039;s security was designed to be upgraded in a forward compatible way and could be [http://en.wikipedia.org/wiki/Post-quantum_cryptography upgraded] if this were considered an imminent threat.&lt;br /&gt;
&lt;br /&gt;
See the implications of quantum computers on public key cryptography here http://en.wikipedia.org/wiki/Quantum_computer#Potential&lt;br /&gt;
&lt;br /&gt;
The &#039;&#039;risk&#039;&#039; of quantum computers is also there for financial institutions, like banks, because they heavily rely on cryptography when doing transactions.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin makes self-sufficient artificial intelligence possible ==&lt;br /&gt;
[[StorJ]]&amp;lt;ref&amp;gt;[http://garzikrants.blogspot.com/2013/01/storj-and-bitcoin-autonomous-agents.html StorJ And Bitcoin Autonomous Agents]&amp;lt;/ref&amp;gt;, a theorized autonomous agent which utilizes humans to build itself and issues autonomous payments for improvement work done, is not a conscious entity. Whatever AI is possible, is not going to be magically more possible simply because it could incentivize human behaviour with pseudonymous Bitcoin payments.&lt;br /&gt;
&lt;br /&gt;
== [[Mining|Bitcoin mining]] is a waste of energy and harmful for ecology ==&lt;br /&gt;
No more so than the wastefulness of mining gold out of the ground, melting it down and shaping it into bars, and then putting it back underground again. Not to mention the building of big fancy buildings, the waste of energy printing and minting all the various fiat currencies, the transportation thereof in armored cars by no less than two security guards for each who could probably be doing something more productive, etc. &lt;br /&gt;
&lt;br /&gt;
As far as mediums of exchange go, Bitcoin is actually quite economical of resources, compared to others.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Economic Argument 1&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
[[Mining|Bitcoin mining]] is a highly competitive, dynamic, almost [http://en.wikipedia.org/wiki/Perfect_market perfect], market.   Mining rigs can be set up and dismantled almost anywhere in the world with relative ease.   Thus, market forces are constantly pushing mining activity to &#039;&#039;places&#039;&#039; and &#039;&#039;times&#039;&#039; where the marginal price of electricity is low or zero.    These electricity products are cheap for a reason.   Often it’s because the electricity is difficult (and wasteful) to transport, difficult to store, or because there is low demand and high supply.  Using electricity in this way is a lot less wasteful than simply plugging a mining rig into the mains indiscriminately. &lt;br /&gt;
&lt;br /&gt;
For example, Iceland produces an excess of cheap electricity from renewable sources, but it has no way of exporting electricity because of its remote location. It is conceivable that at some point in future Bitcoin mining will only be profitable in places like Iceland, and unprofitable in places like central Europe, where electricity comes mostly from nuclear and fossil sources.   &lt;br /&gt;
&lt;br /&gt;
Market forces could even push mining into innovative solutions that have an effective electricity consumption of &#039;&#039;zero&#039;&#039;.   Mining always produces heat equivalent to the energy consumed - for example, 1000 watts of mining equipment produces the same amount of heat as a 1000 watt heating element used in an electric space heater, hot tub, water heater, or similar appliance.  Someone already in a willing position to incur the cost of electricity for its heat value alone could run mining equipment specially designed to mine bitcoins while capturing and utilizing the heat produced, without incurring any energy costs beyond what they already intended to spend on heating.&lt;br /&gt;
&lt;br /&gt;
(Note that this is just an example; mining will not always produce heat equivalent to the energy consumed because some energy is inevitably released as electromagnetic radiation, among others.)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Economic Argument 2&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
When the environmental costs of mining are considered, they need to be weighed up against the benefits.   If you question Bitcoin on the grounds that it consumes electricity, then you should also ask questions like this: Will Bitcoin promote economic growth by freeing up trade?  Will this speed up the rate of technological innovation? Will this lead to faster development of green technologies? Will Bitcoin enable new, border crossing [http://en.wikipedia.org/wiki/Smart_grid smart grid] technologies?  …&lt;br /&gt;
&lt;br /&gt;
Dismissal of Bitcoin because of its costs, while ignoring its benefits, is a dishonest argument. In fact, any environmental argument of this type is dishonest, not just pertaining to Bitcoin.  Along similar lines, it could be argued that wind turbines are bad for the environment because making the steel structure consumes energy.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Ratio of Capital Costs versus Electrical Costs&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The BFL Jalapeno hashes at 5.5 Gh/s using 30W.  That device consumes about $40 per year in electricity (using U.S. residential average of about $0.15 per kWh.)   But the device costs over $300 including shipping.  Thus just about a quarter of all costs over a two-year useful life goes to electricity.  This compares to GPUs where more than 90% of costs over a two-year life went to electricity.  Even more efficient designs can be expected in the future.&lt;br /&gt;
&lt;br /&gt;
== Shopkeepers can&#039;t seriously set prices in bitcoins because of the volatile exchange rate ==&lt;br /&gt;
&lt;br /&gt;
The assumption is that bitcoins must be sold immediately to cover operating expenses. If the shopkeeper&#039;s back-end expenses were transacted in bitcoins as well, then the exchange rate would be irrelevant. Larger adoption of Bitcoin would make prices [http://en.wikipedia.org/wiki/Sticky_%28economics%29 sticky]. Future volatility is expected to decrease, as the size and depth of the market grows. &lt;br /&gt;
&lt;br /&gt;
In the meantime, many merchants simply regularly pull the latest market rates from the exchanges and automatically update the prices on their websites. Also you might be able to buy a put option in order to sell at a fixed rate for a given amount of time. This would protect you from drops in price and simplify your operations for that time period.&lt;br /&gt;
&lt;br /&gt;
== Like Flooz and e-gold, bitcoins serve as opportunities for criminals and will be shut down ==&lt;br /&gt;
&lt;br /&gt;
* Visa, MasterCard, PayPal, and cash all serve as opportunities for criminals as well, but society keeps them around due to their recognized net benefit.&lt;br /&gt;
* Hopefully Bitcoin will grow to the point where no single organization can disrupt the network, or would be better served by helping it.&lt;br /&gt;
* Terrorists fly aircraft into buildings, but the governments have not yet abolished consumer air travel. Obviously the public good outweighs the possible bad in their opinion.&lt;br /&gt;
* Criminal law differs between jurisdictions.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin sera poursuivi par le gouvernement américain comme Liberty Dollars l&#039;a été ==&lt;br /&gt;
&lt;br /&gt;
Liberty Dollars a démarré comme une entreprise commerciale afin d&#039;établir une monnaie US alternative, y compris les billets et pièces physiques, soutenus par des métaux précieux. Ceci, en soi, n&#039;est pas illégal. Ils ont été poursuivis en vertu des lois de contrefaçon parce que les pièces d&#039;argent prétendument ressemblaient à la monnaie américaine.&lt;br /&gt;
&lt;br /&gt;
Bitcoin ne ressemblent pas à la monnaie des États-Unis ou de toute autre nation en aucune manière, d&#039;aspect ou de forme. Bitcoin n&#039;utilise pas le mot &amp;quot;dollar&amp;quot; et le symbole &amp;quot;$&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Bitcoin n&#039;a aucune similitude avec le dollar américain.&lt;br /&gt;
&lt;br /&gt;
Bien sûr, en fait poursuivre et arrêter Liberty Dollars était facile en arrêtant les dirigeants de la société et en saisissant les bureaux et les métaux précieux utilisés comme actifs. Le Bitcoin décentralisé, sans dirigeant, sans serveur, sans bureau, et sans adossement à des actifs tangibles, n&#039;a pas cette même vulnérabilité.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin n&#039;est pas décentralisé parce que les développeurs peuvent dicter le comportement du logiciel ==&lt;br /&gt;
&lt;br /&gt;
Le protocole Bitcoin a été défini par l&#039;inventeur de Bitcoin, [[Satoshi Nakamoto]], et ce protocole a maintenant été largement accepté comme la norme par la communauté des mineurs et des utilisateurs.&lt;br /&gt;
&lt;br /&gt;
Bien que les développeurs du client Bitcoin officiel exercent encore une influence sur la communauté Bitcoin, leur pouvoir de modifier arbitrairement le protocole est très limité. Depuis la sortie de Bitcoin v0.3, les modifications au protocole ont été mineures et toujours en accord avec le consensus communautaire.&lt;br /&gt;
&lt;br /&gt;
Des modifications du protocole, comme l&#039;augmentation de la rétribution par bloc de 25 à 50 BTC, ne sont pas compatibles avec les clients déjà actifs sur le réseau. Si des développeurs créent un nouveau client que la majorité des mineurs perçoit comme corrompu, ou en violation des objectifs du projet, ce client ne serait tout simplement pas reconnu, et les quelques utilisateurs qui tenteraient de l&#039;utiliser verraient leurs opérations rejetées par le réseau.&lt;br /&gt;
&lt;br /&gt;
Il y a aussi d&#039;autres [[: Catégorie: Clients | clients Bitcoin faits par d&#039;autres développeurs]] qui adhèrent au protocole Bitcoin. Plus il y aura de développeurs à créer des clients alternatifs, moins d&#039;efforts seront supportés par les développeurs du client Bitcoin officiel.&lt;br /&gt;
&lt;br /&gt;
== Bitcoin est un système pyramidal ==&lt;br /&gt;
&lt;br /&gt;
Bitcoin est presque l&#039;opposé d&#039;un [[Wikipedia: Pyramid_scheme | système pyramidal]] au sens mathématique. Parce que son algoritme est atypique, aucun avantage exponentiel n&#039;est créé avec l&#039;arrivée de nouveaux utilisateurs. Il y a un avantage quantitatif avec un meilleur intérêt (curiosité) sur le Bitcoin, ou une demande croissante, mais cela n&#039;est, en aucune façon, exponentiel. &amp;lt;ref name=&amp;quot;Jeff_Tucker&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Bitcoin a été piraté == &lt;br /&gt;
&lt;br /&gt;
Dans l&#039;histoire de Bitcoin, il n&#039;y a jamais eu une attaque sur la chaîne de blocs qui ait abouti par de l&#039;argent volé depuis une sortie confirmée. Il n&#039;y a jamais non plus eu de vol signalé résultant directement d&#039; une vulnérabilité dans le client officiel Bitcoin, ou une vulnérabilité dans le protocole. Bitcoin est sécurisé par les fonctions standards de cryptographie. Ces fonctions ont été examinées par des experts en cryptographie et sont considérées comme peu susceptibles d&#039;être cassables dans un avenir prévisible.&lt;br /&gt;
&lt;br /&gt;
Il est sûr de dire que la monnaie elle-même n&#039;a jamais été «piratée». Toutefois, plusieurs sites majeurs utilisant cette monnaie ont été piratés, résultant souvent par un braquage très important de bitcoins. Les faits sur ces braquages ont été fallacieusement rapportés dans certains médias comme piratage du Bitcoin lui-même. Une analogie: Juste parce que quelqu&#039;un a volé des euros dans uné épicerie ne signifie pas que l&#039;Euro, en tant que monnaie, a été «piraté».&lt;br /&gt;
&lt;br /&gt;
La plupart des bitcoins volés sont le résultat d&#039;une insuffisance de sécurité ([[Sécuriser votre portefeuille | sécurité portefeuille]]). En réponse à la vague de vols entre 2011 et 2012, la communauté a élaboré des mesures d&#039;atténuation des risques tels que le [[Wallet_encryption | chiffrement portefeuille]], le soutien à [[BIP_0011 | multiples signatures]], [[How_to_set_up_a_secure_offline_savings_wallet | hors portefeuilles]] , [[Portefeuille Papier| portefeuilles papier]] et [[Hardware_wallet | portefeuilles de matériel]]. Comme ces mesures gagnent en adoption par les marchands et les utilisateurs, le nombre de vols chute.&lt;br /&gt;

&lt;div&gt;== Introduction ==&lt;br /&gt;
&lt;br /&gt;
A moins que vous utilisiez un portefeuille physique il est fortement conseiller de lire cette page.&lt;br /&gt;
&lt;br /&gt;
La sécurité d&#039;un portefeuille à deux objectifs :&lt;br /&gt;
&lt;br /&gt;
# Protéger votre portefeuille d&#039;une perte.&lt;br /&gt;
# Protéger votre portefeuille d&#039;un vol.&lt;br /&gt;
&lt;br /&gt;
Dans le cas où votre portefeuille n&#039;a pas été correctement protéger ( ex : L&#039;avoir mis en ligne avec un mot de passe facile à trouver ) :&lt;br /&gt;
# Vous devez créer un nouveau portefeuille en utilisant une protection approprier sur le long-terme.&lt;br /&gt;
Pour un petit résumé voir aussi : [[Sécurité du portefeuille : Les choses à faire et à ne pas faire]]&lt;br /&gt;
&lt;br /&gt;
== Portefeuille Papier ==&lt;br /&gt;
&lt;br /&gt;
Page principal : [[Portefeuille Papier]]&lt;br /&gt;
&lt;br /&gt;
Les [[Portefeuille Papier|portefeuilles papier]] peuvent être utiliser pour stocker des bitcoins hors-ligne dans un format non digital. Utilisez des portefeuilles papier générés de manière sécuriser permet de faire baisser drastiquement les chances de se faire voler ses bitcoins par des pirates ou des virus informatique. Un portefeuille papier n&#039;est rien d&#039;autre qu&#039;un enregistrement physique de la clé privée de votre portefeuille Bitcoin.&lt;br /&gt;
&lt;br /&gt;
== Portefeuille Physique ==&lt;br /&gt;
&lt;br /&gt;
Les portefeuilles physique sont une avancée majeur dans la sécurité et l&#039;accessibilité des portefeuilles Bitcoin.&lt;br /&gt;
&lt;br /&gt;
Voir la page sur les portefeuilles physique pour plus d&#039;informations sur les types de portefeuilles physique disponible sur le marché.&lt;br /&gt;
&lt;br /&gt;
== Importance des mises à jour de sécurité ==&lt;br /&gt;
&lt;br /&gt;
Aucun logiciel informatique n&#039;est parfait, et de temps en temps certaines vulnérabilités peuvent être trouver dans votre client Bitcoin. C&#039;est pour cela qu&#039;il faut bien faire attention à toujours effectuer les mises à jours de son client Bitcoin, encore plus quand une vulnérabilité est découverte. Nous maintenant une liste de vulnérabilités connues sur le wiki - vous pouvez voir cette page pour des mises à jours. Noté que vous n&#039;avez pas forcément besoin d&#039;avoir la dernière version de votre client Bitcoin : Certains clients, comme le très célèbre et populaire Bitcoin Core ( Anciennement Bitcoin-Qt ), possèdent des anciennes versions avec uniquement des mises à jours de sécurité.&lt;br /&gt;
&lt;br /&gt;
== Sécuriser le portefeuille Bitcoin Core ou bitcoind ==&lt;br /&gt;
&lt;br /&gt;
Bitcoin transactions send Bitcoins to a specific public key. A Bitcoin address is an encoded hash of a public key. In order to use received Bitcoins, you need to have the private key matching the public key you received with. This is sort of like a super long password associated with an account (the account is the public key). Your Bitcoin wallet contains all of the private keys necessary for spending your received transactions. If you delete your wallet without a backup, then you no longer have the authorization information necessary to claim your coins, and the coins associated with those keys are lost forever.&lt;br /&gt;
&lt;br /&gt;
The wallet contains a pool of queued keys. By default there are 100 keys in the key pool. The size of the pool is configurable using the &amp;quot;-keypool&amp;quot; command line argument. When you need an address for whatever reason (send, “new address”, generation, etc.), the key is not actually generated freshly, but taken from this pool. A brand new address is generated to fill the pool back to 100. So when a backup is first created, it has all of your old keys plus 100 unused keys. After sending a transaction, it has 99 unused keys. After a total of 100 new-key actions, you will start using keys that are not in your backup. Since the backup does not have the private keys necessary for authorizing spends of these coins, restoring from the old backup will cause you to lose Bitcoins.&lt;br /&gt;
&lt;br /&gt;
Creating a new address generates a new pair of public and private keys, which are added to your wallet. Each keypair is mostly random numbers, so they cannot be known prior to generation. If you backup your wallet and then create more than 100 new addresses, the keypair associated with the newest addresses will not be in the old wallet because the new keypairs are only known after creating them. Any coins received at these addresses will be lost if you restore from the backup.&lt;br /&gt;
&lt;br /&gt;
The situation is made somewhat more confusing because the receiving addresses shown in the UI are not the only keys in your wallet. Each Bitcoin generation is given a new public key, and, more importantly, each sent transaction also sends some number of Bitcoins back to yourself at a new key. When sending Bitcoins to anyone, you generate a new keypair for yourself and simultaneously send Bitcoins to your new public key and the actual recipient&#039;s public key. This is an anonymity feature – it makes tracking Bitcoin transactions much more difficult.&lt;br /&gt;
&lt;br /&gt;
So if you create a backup, and then do more than 100 things that cause a new key to be used, and then restore from the backup, some Bitcoins will be lost. Bitcoin has not deleted any keys (keys are never deleted) – it has created a new key that is not in your old backup and then sent Bitcoins to it. A backup is therefore recommended roughly every 50 transactions (or address creations) just to be safe.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;[[File:FirstBitcoinBills.jpg|thumb|right|200px|Casascius holding early paper wallets]]&lt;br /&gt;
&lt;br /&gt;
In the most specific sense, a &#039;&#039;&#039;paper wallet&#039;&#039;&#039; is a document containing all of the data necessary to generate any number of Bitcoin [[private key]]s, forming a wallet of keys. However, people often use the term to mean &#039;&#039;any&#039;&#039; way of storing bitcoins offline as a physical document. This second definition also includes &#039;&#039;&#039;paper keys&#039;&#039;&#039; and &#039;&#039;&#039;redeemable codes&#039;&#039;&#039;. A paper key is a single key written on paper that is used multiple times like a wallet (this is strongly [[address reuse|discouraged]]). A redeemable code is a single key intended to be funded and &amp;quot;redeemed&amp;quot; only once: these are commonly used for gifts and as part of physical Bitcoin coins/notes.&lt;br /&gt;
&lt;br /&gt;
Storing bitcoins on paper wallets is not safe unless very strict security precautions are undertaken during their initial preparation. (See below.)&lt;br /&gt;
&lt;br /&gt;
__TOC__&lt;br /&gt;
&lt;br /&gt;
==Use cases==&lt;br /&gt;
&lt;br /&gt;
===Tips and gifts===&lt;br /&gt;
&lt;br /&gt;
By creating a keypair, one can store bitcoins on a physical medium to be left as a tip or a gift.&lt;br /&gt;
The recipient then sweeps the private key to their own wallet.&lt;br /&gt;
&lt;br /&gt;
===Physical tokens===&lt;br /&gt;
&lt;br /&gt;
A trusted provider can hide the private key inside a tamper-resistant token, and issue them as a form of bitcoins.&lt;br /&gt;
This requires those who accept it as payment to trust that when the provider produced the tokens, they loaded them with the correct amount of bitcoins, and that they have not been tampered with since then.&lt;br /&gt;
To redeem the bitcoin value, the token must be destroyed to access the private key.&lt;br /&gt;
Often a bitcoin address is embedded on the outside visible, but there is no guarantee (without destroying the token) that this matches the private key inside, or, even if it does, that the private key is not replicated on multiple tokens or saved by the producer.&lt;br /&gt;
&lt;br /&gt;
===Wallets===&lt;br /&gt;
&lt;br /&gt;
Proper paper wallets are often a very secure way of storing bitcoins, since they are not typically exposed to malware. They can also be easily stored securely in safes and safe deposit boxes. However, it may be more difficult to securely &amp;quot;backup&amp;quot; paper wallets, and due to the current sub-optimal software support, it may be easier to make a mistake that causes loss of bitcoins.&lt;br /&gt;
&lt;br /&gt;
Sometimes people try to use single keys as true bitcoin wallets. However [[address reuse]] is very bad for privacy and security. Because of this, one is forced to choose between hazardous options:&lt;br /&gt;
* &#039;&#039;&#039;Use the key only once to receive, and only once to send the full amount.&#039;&#039;&#039; This requires the user to know the full amount he wants to store in advance, and often leads to the next situation:&lt;br /&gt;
* &#039;&#039;&#039;Create multiple keys.&#039;&#039;&#039; By using more than one key, the user can receive more than once using a different address each time, including using new addresses for change. This is very complicated, and makes it easy to accidentally reuse addresses, produce the wrong change/fee combination, lose some keys, spend hours searching for the right key, etc. Not even skilled bitcoin experts are comfortable managing their own keys manually like this.&lt;br /&gt;
&lt;br /&gt;
Therefore, it is highly recommended that you use proper paper wallets which allow you to generate an infinite number of addresses from a single seed.&lt;br /&gt;
&lt;br /&gt;
==Encoding/formatting==&lt;br /&gt;
&lt;br /&gt;
[[File:BitcoinPaperWallet-sample.jpg|thumb|right|300px|Paper keypair with private key secured beneath folds]]&lt;br /&gt;
[[File:PaperWallets-offlineaddress-com.png|200px|thumb|right|Paper keypair]]&lt;br /&gt;
Proper, multi-key paper wallets usually take the form of a multi-word [[Deterministic wallet | HD wallet]] seed mnemonic. The list of several words corresponds to some binary data that is used to generate all of the addresses. Words are used to make it easier to avoid and correct errors. Trying to memorize an entire seed mnemonic is very difficult and is generally not recommended.&lt;br /&gt;
&lt;br /&gt;
A single key (for use in insecure single-key paper wallets or redeemable codes) can be represented in several formats, but typically the Wallet Import Format (WIF) is used, since keys represented that way are very short (51 characters) and thus easy to re-enter when importing or &amp;quot;sweeping&amp;quot; it for withdrawal.&lt;br /&gt;
&lt;br /&gt;
==Creation of a paper wallet==&lt;br /&gt;
&lt;br /&gt;
===Generation of secure keys===&lt;br /&gt;
&lt;br /&gt;
The private seed is used to prove your right to spend the bitcoins transferred to the paper wallet, and as such should be kept hidden and secret.&lt;br /&gt;
If the private seed on a paper wallet is exposed (for example in a photograph) then the wallet may be used by anyone who sees it.&lt;br /&gt;
To guard against accidental revelation, the private key displayed on the paper wallet may be encrypted or split into several different parts (for example using [https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing Shamir&#039;s secret sharing scheme]).&lt;br /&gt;
At the very least, the private key should be well hidden e.g. by folding the wallet in half and sealing it shut.&lt;br /&gt;
&lt;br /&gt;
Currently, at least [[Armory]] and [[Electrum]] support generating mnemonic codes for their wallets, which can be written down or printed to make a multi-key paper wallet.&lt;br /&gt;
&lt;br /&gt;
Several tools exist for producing single keys, including [[Bitcoin Address Utility]], [[vanitygen]], and [[Cwallet]]. Again, using single keys for anything except one-time &#039;&#039;transfers&#039;&#039; of bitcoins is strongly [[address reuse|discouraged]].&lt;br /&gt;
&lt;br /&gt;
===Web-based key generators===&lt;br /&gt;
&lt;br /&gt;
Some websites feature free open-source client-side keypair/wallet generators written in JavaScript.&lt;br /&gt;
Keypairs/wallets generated by JavaScript or using websites are inherently weak and insecure, and unless the code of the website is audited every time it is used, it may leak the generated keys back to the server—especially if un-audited Javascript is downloaded and run locally.&lt;br /&gt;
Even with careful code auditing, browser plugins or other websites may compromise the environment.&lt;br /&gt;
&lt;br /&gt;
===Recommendations===&lt;br /&gt;
* Disconnecting from the Internet guarantees that that the paper wallet generator is truly self-contained and isn&#039;t transmitting your keys online. &lt;br /&gt;
* Verifying the integrity of the code (and the trustworthiness of the author) is important to make sure a hacker hasn&#039;t modified the download so that it generates predictable seeds instead of truly random ones.&lt;br /&gt;
* Remember, spyware and viruses often attempt to monitor your computer activities so that their authors can steal from you. They are interested in passwords to online accounts, and anything of value. Bitcoin wallets are something of value that have already been targeted by malware. If your computer is infected with spyware or viruses - even if there are no symptoms, or your antivirus isn&#039;t reporting anything - then anything you type, view, or save on your computer, could potentially be stolen by someone remotely controlling your computer. Your private seed can then be intercepted while you enter it, so only enter a Bitcoin private seed into your computer when you are certain it is secure (such as a fresh boot of a LiveCD).&lt;br /&gt;
* The wallet should never be saved to a computer hard drive or sent via email or other network connections.  You should also never scan/type your key into your computer, except at the moment you are using it.&lt;br /&gt;
* If possible, the wallet should be kept hidden, for example by using BIP38 encryption (single keys only), and/or by folding the paper to hide the private key so that a photograph or photocopy of it will not reveal or replicate the private key.&lt;br /&gt;
* A web-based generator should not be used.&lt;br /&gt;
* A generator should use an appropriate source of random numbers (entropy).  This means that the generated keys aren&#039;t predictable.  If the addresses come from a predictable or partially-predictable patterns like pseudorandom numbers &amp;lt;ref&amp;gt;[https://en.wikipedia.org/wiki/Pseudorandomness#Cryptography Pseudorandomness] &#039;&#039; is not enough for strong cryptography&#039;&#039;&amp;lt;/ref&amp;gt;, someone else who can predict the pattern can steal the balance. Randomness should NEVER be human generated, as the human brain is incapable of secure entropy.&lt;br /&gt;
* Remember that unlike wallets (paper or otherwise), a single paper key is only good to receive a single payment, and must be redeemed in its entirety.&lt;br /&gt;
&lt;br /&gt;
===Printer Security===&lt;br /&gt;
&lt;br /&gt;
Some advanced printers have internal storage (even hard drives) that preserve copies of printouts. This is a risk if someone gets access to your printer, or if you dispose of your printer. There is also the possibility that a smart enough printer can be hacked. (Consider [http://en.wikipedia.org/wiki/Stuxnet StuxNet] which was able to rewrite the firmware of non-computer devices indirectly connected to the Internet) If this concerns you, use a &amp;quot;dumb&amp;quot; printer, and never let your printer have access to the Internet or to an Internet-connected computer.&lt;br /&gt;
&lt;br /&gt;
==Redeeming Keys and Withdrawing Funds==&lt;br /&gt;
&lt;br /&gt;
This section applies only to single-key paper &amp;quot;wallets&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Paper keys, when used as wallets, are very different from wallets such as Bitcoin Core in that there is only one address in a paper key rather than a hundred or more online keys that are managed with full software assistance from Bitcoin Core.&lt;br /&gt;
&lt;br /&gt;
There are various methods for copying the private key data to other wallets.&lt;br /&gt;
* bitcoind supports an &amp;quot;importprivkey&amp;quot; RPC method for this purpose.&lt;br /&gt;
* Bitcoin-Qt&#039;s debug console can also be used in a similar way (see also [[How to import private keys in Bitcoin Core 0.7+]]).&lt;br /&gt;
* [[BlockChain.info]] and [[Armory]] can also import them directly into wallets.&lt;br /&gt;
* [http://MyCelium.com/download Mycelium] is a Android mobile wallet with an easy to use &amp;quot;cold storage&amp;quot; spending function. It is also available via Android and iTunes playstore. The iTunes version may not yet support cold storage spending.&lt;br /&gt;
&lt;br /&gt;
Note that importing a private key that may be compromised can result in the entire wallet becoming insecure. For this reason, sweeping (or sending the entire amount to a fresh address) is generally recommended over plain importing.&lt;br /&gt;

== Importance des mises à jour de sécurité ==&lt;br /&gt;
&lt;br /&gt;
Aucun logiciel informatique n&#039;est parfait, et de temps en temps certaines vulnérabilités peuvent être trouver dans votre client Bitcoin. C&#039;est pour cela qu&#039;il faut bien faire attention à toujours effectuer les mises à jours de son client Bitcoin, encore plus quand une vulnérabilité est découverte. Nous maintenant une liste de vulnérabilités connues sur le wiki - vous pouvez voir cette page pour des mises à jours. Noté que vous n&#039;avez pas forcément besoin d&#039;avoir la dernière version de votre client Bitcoin : Certains clients, comme le très célèbre et populaire Bitcoin Core ( Anciennement Bitcoin-Qt ), possèdent des anciennes versions avec uniquement des mises à jours de sécurité.&lt;br /&gt;
&lt;br /&gt;
== Sécuriser le portefeuille Bitcoin Core ou bitcoind ==&lt;br /&gt;
&lt;br /&gt;
Bitcoin transactions send Bitcoins to a specific public key. A Bitcoin address is an encoded hash of a public key. In order to use received Bitcoins, you need to have the private key matching the public key you received with. This is sort of like a super long password associated with an account (the account is the public key). Your Bitcoin wallet contains all of the private keys necessary for spending your received transactions. If you delete your wallet without a backup, then you no longer have the authorization information necessary to claim your coins, and the coins associated with those keys are lost forever.&lt;br /&gt;
&lt;br /&gt;
The wallet contains a pool of queued keys. By default there are 100 keys in the key pool. The size of the pool is configurable using the &amp;quot;-keypool&amp;quot; command line argument. When you need an address for whatever reason (send, “new address”, generation, etc.), the key is not actually generated freshly, but taken from this pool. A brand new address is generated to fill the pool back to 100. So when a backup is first created, it has all of your old keys plus 100 unused keys. After sending a transaction, it has 99 unused keys. After a total of 100 new-key actions, you will start using keys that are not in your backup. Since the backup does not have the private keys necessary for authorizing spends of these coins, restoring from the old backup will cause you to lose Bitcoins.&lt;br /&gt;
&lt;br /&gt;
Creating a new address generates a new pair of public and private keys, which are added to your wallet. Each keypair is mostly random numbers, so they cannot be known prior to generation. If you backup your wallet and then create more than 100 new addresses, the keypair associated with the newest addresses will not be in the old wallet because the new keypairs are only known after creating them. Any coins received at these addresses will be lost if you restore from the backup.&lt;br /&gt;
&lt;br /&gt;
The situation is made somewhat more confusing because the receiving addresses shown in the UI are not the only keys in your wallet. Each Bitcoin generation is given a new public key, and, more importantly, each sent transaction also sends some number of Bitcoins back to yourself at a new key. When sending Bitcoins to anyone, you generate a new keypair for yourself and simultaneously send Bitcoins to your new public key and the actual recipient&#039;s public key. This is an anonymity feature – it makes tracking Bitcoin transactions much more difficult.&lt;br /&gt;
&lt;br /&gt;
So if you create a backup, and then do more than 100 things that cause a new key to be used, and then restore from the backup, some Bitcoins will be lost. Bitcoin has not deleted any keys (keys are never deleted) – it has created a new key that is not in your old backup and then sent Bitcoins to it. A backup is therefore recommended roughly every 50 transactions (or address creations) just to be safe.&lt;br /&gt;

&lt;div&gt;Cet article ne doit pas être considérer comme un remplacement d&#039;articles plus détaillés sur des meilleurs moyens de sécuriser son portefeuille, mais comme une liste de point clé dans la sécurité de votre portefeuille :&lt;br /&gt;
&lt;br /&gt;
* Vous devez crypter votre portefeuille.&lt;br /&gt;
* Vous devez faire une sauvegarde de votre portefeuille.&lt;br /&gt;
* Vous devez utiliser des portefeuilles recommandés de cette liste : https://bitcoin.org/fr/choisir-votre-porte-monnaie.&lt;br /&gt;
* Vous devez garder votre OS à jour et avoir un anti-virus.&lt;br /&gt;
* Vous devez utiliser un portefeuille papier ou un portefeuille physique pour stocker de grosses sommes.&lt;br /&gt;
* Vous NE devez PAS sauvegarder votre portefeuille dans un stockage en ligne ( Mega, Dropbox, Google Drive, etc... ).&lt;br /&gt;
* Vous NE devez PAS réutiliser des adresses ( Ce conseil s&#039;applique pour les portefeuilles papier aussi ).&lt;br /&gt;
* Vous NE devez PAS générer une clé privée qui servira pour un portefeuille papier sur une machine connectée à Internet. Si c&#039;est pour un stockage hors-ligne, cela ne doit JAMAIS être fait sur une machine connectée à Internet.&lt;br /&gt;
Si pour n&#039;importe quelles raisons vous développez votre propre portefeuille, vous NE devez PAS rajouter des outils cryptographique par vous-même. Regardez cet exemple venant de Sony comme exemple de ce qui peut arriver de mal : http://www.exophase.com/20540/hackers-describe-ps3-security-as-epic-fail-gain-unrestricted-access/&lt;br /&gt;

Aucun logiciel informatique n&#039;est parfait, et de temps en temps certaines vulnérabilités peuvent être trouver dans votre client Bitcoin. C&#039;est pour cela qu&#039;il faut bien faire attention à toujours effectuer les mises à jours de son client Bitcoin, encore plus quand une vulnérabilité est découverte. Nous maintenant une liste de vulnérabilités connues sur le wiki - vous pouvez voir cette page pour des mises à jours. Noté que vous n&#039;avez pas forcément besoin d&#039;avoir la dernière version de votre client Bitcoin : Certains clients, comme le très célèbre et populaire Bitcoin Core ( Anciennement Bitcoin-Qt ), possèdent des anciennes versions avec uniquement des mises à jours de sécurité.&lt;br /&gt;

Bitcoin transactions send Bitcoins to a specific public key. A Bitcoin address is an encoded hash of a public key. In order to use received Bitcoins, you need to have the private key matching the public key you received with. This is sort of like a super long password associated with an account (the account is the public key). Your Bitcoin wallet contains all of the private keys necessary for spending your received transactions. If you delete your wallet without a backup, then you no longer have the authorization information necessary to claim your coins, and the coins associated with those keys are lost forever.&lt;br /&gt;
&lt;br /&gt;
The wallet contains a pool of queued keys. By default there are 100 keys in the key pool. The size of the pool is configurable using the &amp;quot;-keypool&amp;quot; command line argument. When you need an address for whatever reason (send, “new address”, generation, etc.), the key is not actually generated freshly, but taken from this pool. A brand new address is generated to fill the pool back to 100. So when a backup is first created, it has all of your old keys plus 100 unused keys. After sending a transaction, it has 99 unused keys. After a total of 100 new-key actions, you will start using keys that are not in your backup. Since the backup does not have the private keys necessary for authorizing spends of these coins, restoring from the old backup will cause you to lose Bitcoins.&lt;br /&gt;
&lt;br /&gt;
Creating a new address generates a new pair of public and private keys, which are added to your wallet. Each keypair is mostly random numbers, so they cannot be known prior to generation. If you backup your wallet and then create more than 100 new addresses, the keypair associated with the newest addresses will not be in the old wallet because the new keypairs are only known after creating them. Any coins received at these addresses will be lost if you restore from the backup.&lt;br /&gt;
&lt;br /&gt;
The situation is made somewhat more confusing because the receiving addresses shown in the UI are not the only keys in your wallet. Each Bitcoin generation is given a new public key, and, more importantly, each sent transaction also sends some number of Bitcoins back to yourself at a new key. When sending Bitcoins to anyone, you generate a new keypair for yourself and simultaneously send Bitcoins to your new public key and the actual recipient&#039;s public key. This is an anonymity feature – it makes tracking Bitcoin transactions much more difficult.&lt;br /&gt;
&lt;br /&gt;
So if you create a backup, and then do more than 100 things that cause a new key to be used, and then restore from the backup, some Bitcoins will be lost. Bitcoin has not deleted any keys (keys are never deleted) – it has created a new key that is not in your old backup and then sent Bitcoins to it. A backup is therefore recommended roughly every 50 transactions (or address creations) just to be safe.&lt;br /&gt;
