I think I'm in agreement that the codepage is a dead end as well.
Think it's got to be something architecturally. Working on getting a C-
compiler to be able to build it natively. The fact that it works as
advertised on one machine, but not on the other seems to vindicate the
code otherwise.
Verified with my group that it is, indeed, an implementation of SHA1.
Looked at Helmut Tessekar's stuff. His function only returned a
char(33) string. Haven't done C for years, so I'm not ready to tackle
my own mods.
