Add an option to use RustCrypto AES #9

Closed mberry closed 1 year ago

mberry commented 2 years ago

Use rustcrypto for the 90's mode AES functions.

Kyber uses some intermediate functions not exposed by the rustcrypto crate, namely aes256ctr_init and aes256ctr_squeezeblocks

The PRF is already implemented yet not in use.

Benchmarking this it seems best to only use the rustcrypto version, both for speed and a bitslice impl

Implemented with 90s-fixslice
