Hi Ira,
So we want a series of more precise keywords, like for instance:
- sha-224
- sha-256
- sha-384
- sha-512
- sha-512/224
- sha-512/256
- sha3-224
- sha3-256
- sha3-384
- sha3-512
- shake128
- shake256
and so on.

Neither the keyword nor the description is clear as to which SHA generation is being used. Is this SHA-0 or SHA-1? Do we need to define additional keywords to bring this up-to-date?
