What's the best tool to crack a Blockchain.info version 0 wallet?
https://github.com/magnumripper/JohnTheRipper/issues/2164 says use btcrecover
https://github.com/gurnec/btcrecover/issues/97#issuecomment-322803105 seems to suggest JohnTheRipper
So which is it? I have tried btcrecover using the tokens which I thought were in the password without success. So will need to try a dictionary approach (1-2 words followed by 0-4 digits).
Also, i seem to have two different versions of the same wallet.aes.json. The one they sent in the original email in early 2012 and the one that is downloaded when i call the
https://blockchain.info/wallet/{id}?format=json&resend_code=false
How can this be, unless they held the original unencrypted wallet and use two different methods (e.g. different PBKDF2 key stretching)?
Finally, can anyone tell me whether the 10 character minimum password length was mandatory during early 2012?
