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. WebIn Crypto++ you're directly passing a broken key to ecb_encryptor. AES supports keys of 16, 24 and 32 bytes length and nothing in between. But you're providing a 10 byte key and tell Crypto++ that the key is actually 32 byte long. This probably results in a random key because the remaining bytes in memory probably contain some junk values. cyclopithecus
