Aloha!

We had some disussions regarding block cipher to be implemented. I think
it was Rob who mentioned that there is some lack of trust in AES-192 and
AES-256. That the important version was AES-256.

What version of AES do we need for the first use cases? AES-128 is ok?

If we want to implement a PRNG based on the CTR_DRBG as specified in SP
800-90 we will (I believe) need AES-256.
