SHA Hashers

[Jimmy Johnson]

I updated my Secure Hash Algorithms cluster.  The SHA classes have no outside dependencies.  (An experimental cluster is available that depends on JJ_NATURAL override cluster, but it's just there for historical/academic reasons.)

There is also a GUI Hasher Utility program with its ecf file.  I included a finalized MacOS executable.  Like to know if it is useful to anyone.
