Here is how to use a passphrase to generate priv keys and corresponding Bitcoin addresses
- Chose a passphrase of at least 7 words and 40 characters, e.g. "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks"
- Run ./pp2k.py --pwpathhome/jackjack/dev/bitcoin/pywallet/ --passphrase "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks"
- The console returns:
- A random code, a 11-digit number, that you must remember or save it somewhere, for example in your mobile phone where nobody can think it's bitcoin related
- Your first 10 privkeys
- The corresponding 10 bitcoin addresses if you downloaded pywallet and provided the correct path to pp2k
The code makes stealing your coins nearly impossible even if one knows your passphrase (more than 2 months to test all the possibilities)
If you want more than 10 keys, use the --size flag (maybe with the --code flag if you want to chose it)
If you want to retrieve a key, use the --code and the --keynumber flags
