Aes256 block size
Common Crypto only supports AES with a block size of 128-bits. For a 256-bit block size you need to use Rijndael from a 3rd party implementation. ,But does the padding precipitate a weakness in the encryption? If padding oracle exist then you can decrypt the entire ciphertext in 128 ...
