AES-512 isn't supported by the PHP openssl library, if I remember
correctly. But AES-256 would be possible. Actually this is something we
already thought about. We just need some time to implement it with a
proper migration routine. I already have some ideas how this could work.
Are you interested in implementing it? If you want I could give you some
pointer and assist you if needed.
