lib/crypto/sha512.c contains implementations of SHA-384 and SHA-512,
which are part of SHA-2. The SHA-3 equivalents are SHA3-384 and
SHA3-512.
We should move the SHA-3 code into lib/crypto/, just as I've done for
SHA-1 and SHA-2. I just haven't gotten to it yet. Nor have I
implemented SHAKE support, which would be new.
Contributions appreciated!
