Re: Encrypt private key on paper wallet using bitaddress.org
So I would like to have the printed private keys encrypted with a passphrase. What would be the best way to realize this?
Wait for the next release of BitAddress.
Or, take your chances with the version that has not yet been vetted by the community as being safe. If you know javascript and cryptography you might be qualified to make that conclusion yourself, but for now it is getting that vetting.
From another thread:
This solution (encrypted paper wallets) robably isn't ready for prime time, but give it a few weeks and that will probably become a very good method for offline / long term savings that is secure.
I changed the colour to blue for encrypted paper wallets to provide distinction between encrypted/unencrypted paper wallets - a version in the original yellow is included in case you really like yellow, just delete 'note_encrypted.png' and rename 'note_yellow.png' in its place.
