Generates a paper wallet for bitcoin
I did this project as an exercise in generating a paper wallet without using any bitcoin specific libraries. Instead this project uses standard java for the cryptography and BouncyCastle as a crypto provider.
I included a Base58 class from Google. Java includes a Base64 class, but not Base58. It seems very uncommon.
Running this project creates public/private keys in Wallet Import Format (WIF), encodes them as QR codes and creates a PDF with the QR codes and the WIF as text. At this point it's hard coded to use my included background image (background.png), but this could be tweaked to allow a user to add an image.
When you gradle run this project, it will produce a wallet.pdf file. Subsequent runs will overwrite this file.
The output file will look like this:
If you use this code, you bear all the responsibility of risks that can occur with buying, selling and storing bitcoin. I am not responsible for any losses you might experience.
