						</p>
						<h3 id="securitystep0title" class="i18n">Step 1. Follow the security checklist recommendation</h3>
						<p id="securitystep0" class="i18n">
							First step is to <strong>download</strong> this website from <a href="https://github.com/OBAViJEST/EsperPaperWallet/archive/master.zip">here</a> and open the index.html file directly from your computer. For extra security, <strong>unplug your Internet access</strong> while generating your wallet.
						</p>
						<h3 id="securitystep1title" class="i18n">Step 2. Generate new address</h3>
						<p id="securitystep1" class="i18n">
							Choose your currency and click on the "Generate new address" button.
						</p>
						<h3 id="securitystep2title" class="i18n">Step 3. Print the Paper Wallet</h3>
						<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 4. 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 5. 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>
						<h3 id="securitystep5title" class="i18n">Step 6. Keep your private key secret</h3>
						<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>
						<p>
							<strong id="securitystep6" class="i18n">Please test spending a small amount before receiving any large payments.</strong><br /><br />

						</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>
