Re: Bitcoin Cipher/puzzle - 0.56 Prize ! Bitcoins

Another hint for combatants who are struggling like me: most of the chars in #10 are sitting in the checksum part of the B58 private key.

I'm looking at https://en.bitcoin.it/wiki/Wallet_import_format and don't see you can take advantage of that fact.
Don't you have to decode the base58 first before you can remove the 4 byte checksum?

This site here: https://gobittest.appspot.com/PrivateKey is actually quite useful for doing this. It also does everything step by step so you can understand the process.
