<b>Step 1: Calibrate Printer</b><br />
Before printing out a wallet you'll need to "calibrate" your output using the <em>zoom</em> and <em>horizontal&nbsp;shift</em> adjustments to accommodate your particular browser / printer combination. Without adjustment, your wallet may print out too small or with a misaligned reverse side.</span>
<br /><br />
<span id="instructions3"><b>Step 2: Print Front</b><br />
Next you will print out the front side of your wallet. A public address and private key will automatically be generated, or you can supply your own key by rolling dice, shuffling cards, etc. You may also duplicate an existing paper wallet or provide a "vanity" address if you have one. If you are printing several wallets, it's possible to <a href="https://bitcoinpaperwallet.com/printing-and-paper-tips/" target="_blank">print two per page</a>.</span>
<br /><br />
<span id="instructions4"><b>Step 3: Print Back</b><br />
You will put the same page back in your printer (but flipped over) to print out the back side of your wallet. This isn't just for good looks: the back side design includes additional tamper-resistant safeguards.</span>
<br /><br />
<span id="instructions5"><b>Step 4: Cut, Fold, Seal &amp; Fund</b><br />
Find your scissors!

<b>If you are making a paper wallet for a <a href="https://en.bitcoin.it/wiki/Vanitygen" target="_blank">vanity address</a>, or duplicating an existing paper wallet:</b>
<br />
<br />
In this case, simply enter your private key in Wallet Import Format (or scan it using the "validate" feature on this web page.) WIF keys always begin with the number 5 and look something like this: '5JnwJNC7q3...' <em>The public address, e.g. '1vanityABC456...' is automatically calculated using the private key, so you only need to provide the private key.</em>
<br />
<br />
<b>If you want to roll dice or shuffle a deck of cards to generate a key:</b>
<br />
<br />
Maybe you don't trust that this software (or computers in general) can generate sufficiently random numbers. In this case, you can supply your own random data points from virtually any source. For example, you can roll a six sided die at least 62 times and enter each roll in sequence, e.g. '15249385...' Or, you can mix up a deck of 52 playing cards (after thoroughly shuffling it at least 10 times) and enter at least the top 31 cards in this format: 5S-10H-AC-... (where 5S = 5 of Spades, 10H = 10 of Hearts, AC = Ace of Clubs, etc.)
<br />
<br />
<em>No special formatting is required</em>. Just type in a great deal of (truly) random text from any source, and whatever you supply will be SHA256 hashed and converted into a private key and public address.
<br />
<br />
<b>If you want to make a paper wallet which can <em>also</em> be accessed using a passphrase (AKA a "brain wallet"):</b>
<br />
<br />
You can make a so-called "brain wallet" by supplying a VERY secure passphrase like '1852 Adobe Cloud SMASH fuzzy steamzonk'. <em>Be extremely careful doing this because a wallet generated using an insecure passphrase is virtually guaranteed to have its balance stolen within minutes of receiving funds!</em>.
<br />
<br />The resulting paper wallet will still have an ordinary crypto-looking private key and public address, but you will <em>also</em> be able to retrieve your wallet contents by entering your passphrase into the 'verify' tab of this service or a similar service such as <a href="https://brainwallet.org" target="_blank">brainwallet.org</a>.<br /><br />
<strong>Note:</strong> supplying a brain wallet passphrase is different from BIP38-encrypting your wallet with a passphrase.

<h2>About "BIP38" Encryption</h2>
<p>
The advantage to encrypting your paper wallet is that if your paper wallet is stolen or otherwise exposed, the balance on the wallet is safe unless the passphrase used to encrypt the wallet is guessed. However, if you encrypt your private key with BIP38 and you lose your passphrase, it will be impossible for you to recover the funds you have sent to this wallet.</p>
<p>Also, note that not many <script type="text/javascript">document.write(window.currencyName);</script> wallet applications or web services are able to import BIP38 private keys. In this case, you will have to use the "Validate" feature on this webpage to extract the unencrypted Wallet Import Format (WIF) key as an intermediate step before sweeping the balance.</p>
<p style="color: red;">WARNING: Before sending any funds to a BIP38-encrypted wallet, first do a test make sure you are able to decrypt the printed private key back to ordinary WIF format.</p>
<p>In short, if you do not have a strong understanding of the BIP38 encryption and decryption workflow, <strong>click cancel</strong>, print your paper wallet out without encryption, and keep it safe the same way you would jewels or cash.
