If you take one hash algorithm for encryption and data verification, a
this causes problems for one or the other. Why not use two algorithms
with different keys made especially for encryption and data?

I think you are confused. A hash algorithm has no keys in general. You use
an encryption algorithm for encryption and a hash algorithm for
verification.
nd almost everyone uses a different algorithm for hashes and for
encryption. While you can make an encryption algorithm out of a hash and a
hash algorithm out of an encryption one, one almost always does not do so.
