WebJan 2, 2016 · The number of rounds is 10, 12 or 14 for the 128, 192 and 256 bit key size respectively. The overall algorithm behind the AES cipher remains the same. The block size is simply the amount of bits or bytes that can be transformed by the block cipher. It is the input and output size of the keyed block cipher. WebAug 18, 2024 · Paul used an encryption program to encrypt his bitcoin address information (including his private key!), using AES-256-CBC. The program uses a very simple (and very weak) key derivation function to derive a key and an iv from a password provided by the user, based on just a single round of SHA384 hashing of the password.
