Is it possible to implement more hashing algorithms?

Here is a list of hashing algorithms from HashTab 6.0 (without commercial license), you can also see them via click “Option” link:

Some of these could be useful, though hashcheck already supports SHA3/keccak though it probably could use an update to some of the newer FIPS algorithms found here https://github.com/gvanas/KeccakCodePackage (as well as maybe some better CPU optimizations for those of us that can use them, or a modular design to add your own hash plugin). would also be nice to have more configuration like what default hash algo to use, but overall I'm glad someone is keeping this program alive.
