Generally improved instructions. Added a "security checklist" which helps to check for a few important security features, e.g. modern javascript crypto support in browser. Merged in a few recent code changes from bitaddress.org.

**** LOOKING FOR THE ZIP FILE TO DOWNLOAD? ************************************

If you're on already at https://github.com/cantonbecker/bitcoinpaperwallet

Then just look for the button that says "Download ZIP". Look to your right -->

|
|
|
This project is a fork of bitaddress.org, the original trustworthy
|
|
JavaScript powered offline bitcoin address generator.
|
|
|
|
This attractive paper wallet design is two-sided and folds up to
|
|
hide the private key. Optional tamper-evident hologram tape can be purchased
|
|
to provide extra security against snooping. This generator is ONLY
|
|
for generating secure paper wallets, either using Javascript-based cryptography
|
|
or by supplying keys you have generated using your own means (vanitygen, dice.)
|
|
|
|
Use bitaddress.org if you need BIP38, brain wallets, or bulk addresses.
|
|
|
|
|
|
*** HOW TO USE THIS GENERATOR ***
|
|
|
|
1) Extract the ZIP file
|
|
2) Open up the 'generate-wallet.html' file with your web browser.
|
|
3) Follow the steps for calibrating your printer and then printing
|
|
the front and back of each wallet. Use landscape mode when printing!
|
|
|
|
Rendering and printing seems to work best using:
|
|
|
|
OS X: Safari or Chrome or Firefox
|
|
Windows: Chrome or Firefox
|
|
Linux: Firefox
|
|
|
|
|
|
*** COMPARED WITH BITADDRESS.ORG ***
|
|
|
|
Images and resources have been moved out of the .html file (where they were
|
|
base-64 encoded) and into an images directory to make the code easier to review.
|
|
|
|
All cryptographic functions are verifiably identical to those in bitaddress.org.
|
|
(Run a "diff" between this project and bitaddress.org if you want to be sure.)
|
|
|
|
You can also bypass the random key generator and supply your own keys or so-called
|
|
"vanity addresses".
|
|
|
|
|
|
*** HOW TO VERIFY THE AUTHENTICITY OF THIS DOWNLOAD ***
|
|
|
|
After downloading the ZIP package for this generator, you should find a file
|
|
named generate-wallet.html.sig which you can use to:
|
|
|
|
* Verify that generate-wallet.html hasn't been tampered with, and
|
|
* Get proof that it really was authored by Canton Becker (canton@gmail.com)
|
|
whose GPG public key and fingerprint should be confirmed at http://cantonbecker.com
|
|
|
|
For example, if you have GPG installed, you should be able cd to the appropriate
|
|
directory and type in these two commands:
|
|
|
|
gpg --recv-key 36E1D9B6
|
|
gpg --verify --with-fingerprint generate-wallet.html.sig generate-wallet.html
|
|
|
|
And then verify the resulting signature's fingerprint against Canton Becker's
|
|
published fingerprint at http://cantonbecker.com
|
|
|
|
If you get warnings like "This key is not certified, there is no indication that
|
|
the key belongs to the owner" do not worry, this is normal.

Now Bitcoin addresses and their corresponding private key can be conveniently
|
|
generated in a web browser.
|
|
|
|
The bitaddress.org project provides an all-in-one HTML document with embedded
|
|
JavaScript/Css/Images. The JavaScript is readable not minified and contains no
|
|
XMLHttpRequest's (no AJAX). The benefit of this technique is you can load the
|
|
JavaScript locally and trust that the JavaScript did not change after being
|
|
loaded.

END USER NOTES:
|
|
1) To print QRCode in IE8 you must enable the "Print Background Colors and
|
|
Images" checkbox on the "Page Setup" screen.
|
|
2) For Bulk Wallet I recommended using Google Chrome, it's the fastest.
|
|
3) Requires IE8+, Firefox, Chrome or sufficient JavaScript support.
|
|
4) Mobile Safari only works with iPhone4 or newer devices.
|
|
Older devices timeout while executing JavaScript.
|
|
5) DO NOT use Opera Mini it renders JavaScript output server side, therefore
|
|
they might record the private key you generated.
|
|
6) Art Wallet does not work properly in IE8 due to CSS limitations.
