Hello, The Bitcoin QT client allows me to sign a message, and extract a public key from that signature itself. I am supposed to then hash this signature in Base58Checked format and then extract the key. The code to extract the key from a signature is here http://stackoverflow.com/a/20000007/328397 The code to get the Base58 address is on the same page, or just paste the extracted public key here: http://gobittest.appspot.com/Address Since I know the Base58Checked encoder works as intended, and it appears the key extraction code works as well, I suspect it may be how I知 presenting the Endian that I知 presenting Q to the hash utility, or even an encoding bug, Here are some tests from the Bitcoin QT client that produce valid results in the client, but I can稚 get it to work in C#: Sig ICHD2obqklY8dVBvjwwiDL3c7QkOnOif0tRlbcM+uk7vnuA0LZu6mVsKMx3Nvk7vdiV28cHO7IRuqXwzO3A3m3A= Message test123 Hashed Public key - 15NGbNHePvuxKJrSV7Qy7Z9pKjxJDo39nV Sig: IEMtA9uGW2x70/qxAaPuE4Fb/H5+Dq+bl0UyMHZXoO7SX4vfXQcg22VafERUMTT5AfpXbTesAk5NSYnPVYulrTM= Message test123 Hashed Public Key - 191FLr28ee3ahg3yDJDLzoS9jfjUvDouzL Any assistance would be appreciated.
