MySQL aes_encrypt padding scheme?

Question

Does anyone know what padding scheme mysql uses for their aes_encrypt?

I've done a lot of googling, and all I found was "byte padding". But that's too general!

Thanks

The data padding is done per RFC3369/PKCS#5. Keys are zero padded. Unfortunately, neither of these are documented, but I got the information from this bug report:
