Reading this stackoverflow Q&A it seems as if the size of the IV is the size of the block which is always 128 bit (= 16 bytes) in AES, even if the keysize is larger than the block size. In addition, the IV can be transmitted independently or included as part of the session setup prior to message exchange. (Regardless of whether I'm in error, it would sure be nice to see an exception thrown which says what the correct length is.). (16 byte for AES 128). For a recipient to decrypt the encrypted message, they must know the IV. len_block [source] Return the block size in bytes. It should work without the hexlify.
