Topic: AES-256-CBC and Private Key (Read 202 times)
What software are you using to decrypt the key?
I am at the final stage. I am now working on checking the encryption for the private keys inside the wallet.
Why does the calculation not work for decrypting private key?
I have the correct private key which was derived from Bitcoin string within Bitcoin2john.py script for wallet.dat.
I have double sha 256 public key for the above address.
I have gotten the unencrypted master key data from the following function in crypter.cpp:
bool DecryptSecret(const CKeyingMaterial& vMasterKey, const std::vector& vchCiphertext, const uint256& nIV, CKeyingMaterial& vchPlaintext)
std::string MasterKey (vMasterKey.begin(), vMasterKey.end());
The error I am getting is as follows: Given final block not properly padded. Such issues can arise if a bad key is used during decryption. Any help on this will be greatly appreciated with a small tip of thanks to your address.
