Argon2i takes bytes, generates a Blake3 hash as salt, generates an argon2i key.

Blake2b takes bytes and returns a blake2b 256 bit hash.

Blake3 takes bytes and returns a lyra2rev2 256 bit hash.

DivHash first runs an arbitrary big number calculation involving a very large integer, and hashes the result.

Hash computes the hash of bytes using the named hash.

Keccak takes bytes and returns a keccak (sha-3) 256 bit hash.

Scrypt takes bytes and returns a scrypt 256 bit hash.

Skein takes bytes and returns a skein 256 bit hash.

Stribog takes bytes and returns a double GOST Stribog 256 bit hash.

X11 takes bytes and returns a X11 256 bit hash.

HashReps allows the number of multiplication/division cycles to be repeated before the final hash, on release for mainnet this is probably set to 9 or so to raise the difficulty to a reasonable level for the hard fork.
