aes_encrypt_cbc() + AES_CYPHER_256 w/ *data len < 24 == bad encrypt/decrpt

[MattDralle]

Maybe I'm missing something, but when I use aes_encrypt_cbc() || aes_encrypt_ecb + AES_CYPHER_256 + 32 byte key with a *data that is <= 23 bytes long, the encrypt/decrpt doesn't work right. If I increase *data to 24 or greater, works great. Also, if I use a 24 or 16 byte key with AES_CYPHER_256, it works with *data < 24 bytes.

Bug, or me?

Thanks,
