> AES UDFs - *aes_encrypt* and *aes_decrypt* currently support only the default AES cipher transformation which is basically AES/ECB/PKCS5P transformation, as it is hardcoded.
> ECB mode is inherently weak, as it produces the same ciphertext for identical blocks of plain text.
> We intend to make this definition configurable to support other strong CTR / GCM modes.
