            <p id="securitystep0" class="i18n">
              First step is to <strong>download</strong> this website from <a href="https://github.com/MichaelMure/PaperWallet/archive/master.zip">Github</a> and open the index.html file directly from your computer. It's just too easy to sneak some evil code in the 6000+ lines of javascript to leak your private key, and you don't want to see your fund stolen. Code version control make it much easier to cross-check what actually run. For extra security, <strong>unplug your Internet access</strong> while generating your wallet.
            </p>
            <h3 id="securitystep1title" class="i18n">Step 1. Generate new address</h3>
            <p id="securitystep1" class="i18n">
              Choose your currency and click on the "Generate new address" button.
            </p>

            <p id="securitystep2" class="i18n">
              Click the Paper Wallet tab and print the page on high quality setting. <strong>Never save the page as a PDF file to print it later since a file is more likely to be hacked than a piece of paper.</strong>
            </p>
            <h3 id="securitystep3title" class="i18n">Step 3. Fold the Paper Wallet</h3>
            <p id="securitystep3" class="i18n">
              Fold your new Paper wallet following the lines.
              <img src="images/foldinginstructions.png" alt="Fold in half lengthwise, and then in three widthwise." /><br />
              You can insert one side inside the other to lock the wallet.
            </p>

            <h3 id="securitystep4title" class="i18n">Step 4. Share your public address</h3>
            <p id="securitystep4" class="i18n">
              Use your public address to receive money from other crypto-currency users. You can share your public address as much as you want.

            <p id="securitystep5" class="i18n">
              The private key is literally the keys to your coins, if someone was to obtain it, they could withdraw the funds currently in the wallet, and any funds that might be deposited in that wallet.

          <p class="faqAnswer" id="faqQuestion1">
            We try to make it that way ! The core of the tool, that generate the keys is 99% the same as the well reviewed bitaddress.org. We only changed it to be able to generate addresses for different crypto-currencies.
          </p>
          <p class="faqAnswer" id="faqQuestion1.1">
We think that having a unique generator for multiple currencies lead to a much better reviewed tool for all than having a myriad of half-backed generators.
Changes made to this generator are available on Github in small and divided commits and those are easy to review and reuse.
Walletgenerator.net use the same security measures as the original project. All-in-one html document, no ajax, no analytics, no external calls, no CDN that can inject anything they want. And trust us, we have seen some nasty things when reviewing some wallet generator.

          <h3 class="faqQuestion"><a class="faqLink" onclick="ninja.toggleFaqQuestion('faqQuestion2');">&#8226; Why should I use a paper wallet ?</a></h3>
          <p class="faqAnswer" id="faqQuestion2">
              Advantages of a paper wallet are multiple:<br/><br/>
              <span class="faqListBullet">&#8658;</span> They are not subject to malwares and keyloggers<br/>
              <span class="faqListBullet">&#8658;</span> You don’t rely on a third party’s honesty or capacity to protect your coins<br/>
              <span class="faqListBullet">&#8658;</span> You won't lose your coins when your device break

          <h3 class="faqQuestion"><a class="faqLink" onclick="ninja.toggleFaqQuestion('faqQuestion3');">&#8226; How to use a paper wallet ?</a></h3>
          <p class="faqAnswer" id="faqQuestion3">
            Once you have generated and printed a wallet, you can send coins to the public address, like for any wallet. Store your paper wallet securely. It contains everything that is needed to spend your funds. Consider using BIP38 to secure your paper wallet with a password.
          </p>

          <h3 class="faqQuestion"><a class="faqLink" onclick="ninja.toggleFaqQuestion('faqQuestion4');">&#8226; How to spend the coins stored in a paper wallet ?</a></h3>
          <p class="faqAnswer" id="faqQuestion4">
            You will need to import your private key in a real client, that you can download from the currency website. The exact method to do that will depend on the client. If there is no integrated method, you can usually fall back to the debug console and use the command “importprivkey [yourprivatekey]“.
          </p>

          <h3 class="faqQuestion"><a class="faqLink" onclick="ninja.toggleFaqQuestion('faqQuestion5');">&#8226; How walletgenerator.net is different than another wallet generator ?</a></h3>
          <p class="faqAnswer" id="faqQuestion5">
            It’s not that different. You will find another design for the paper wallet and some improvements here and there. The big difference is that this is a unique project for a lot of currencies, so more people can review it and check its safety.
          </p>

          <h3 class="faqQuestion"><a class="faqLink" onclick="ninja.toggleFaqQuestion('faqQuestion7');">&#8226; Can you add support for cryptocurrency XYZ ?</a></h3>
          <p class="faqAnswer" id="faqQuestion7">
            Absolutely ! To help us do that, you can <a href="https://docs.google.com/forms/d/1nPIvukVWxlaveUPEUAEhGKwvEuwJiPSgs5zc5LhDVpk/viewform">fill this  form</a>. But keep in mind that there is some currency that we cannot support. If the developers made some change in the address format, we won’t hack the crypto core of the project and take the risk to tamper the security of the others currencies.
            You can also implement the support yourself by following this <a href="https://github.com/MichaelMure/WalletGenerator.net/wiki/How-to-add-a-new-currency">non-developer How-To</a>

          <h3 class="faqQuestion"><a class="faqLink" onclick="ninja.toggleFaqQuestion('faqQuestion8');">&#8226; Why should I make a donation ?</a></h3>
          <p class="faqAnswer" id="faqQuestion8">
            Donations money are used to pay our hosting service provider, but it’ll also be used to make walletgenerator.net more secure as we plan to organize a CrowdCurity campain as soon as we get enough money to pay for it.
          </p>

          <h3 class="faqQuestion"><a class="faqLink" onclick="ninja.toggleFaqQuestion('faqQuestion9');">&#8226; I found a bug, what shall I do ?</a></h3>
          <p class="faqAnswer" id="faqQuestion9">
            You can report bugs using GitHub. You can also contact us using our Twitter account (<a href="http://twitter.com/WalletGenerator" target="_blank">@WalletGenerator</a>). Just try to explain clearly what is wrong and we will try to fix the bug as soon as possible.

          <p class="faqAnswer" id="faqQuestion11">
            Donation are always welcome, but you can also help us translate the website. It's really easy. Just add "?i18nextract=LANGUAGECODE" in the end of the url (for instance http://walletgenerator.net/?i18nextract=es for Spanish). You will see at the end of the page a pre-filled javascript array ready to be translated. Translate or correct it, and send it to us the way you prefer. Even partial translation are helpful !

            </div>
            <div id="detaila1" class="answer i18n">An important part of creating a crypto-currency wallet is ensuring the random numbers used to create the wallet are truly random. Physical randomness is better than computer generated pseudo-randomness. The easiest way to generate physical randomness is with dice. To create a crypto-currency private key you only need one six sided die which you roll 99 times. Stopping each time to record the value of the die. When recording the values follow these rules: 1=1, 2=2, 3=3, 4=4, 5=5, 6=0. By doing this you are recording the big random number, your private key, in B6 or base 6 format. You can then enter the 99 character base 6 private key into the text field above and click View Details. You will then see the public address associated with your private key. You should also make note of your private key in WIF format since it is more widely used.</div>
