for hash registries.

When I have analysed problems with "hashlib" (some time ago,
my memory may not be completely trustworthy), I got the
impression that "hashlib" essentially delegates to the
"openssl" libraries for the real work and especially
the supported hash types. Thus, I suspect that
your "FOO_login()" does something which confuses "openssl".
One potential reason could be that it loads a bad version
of an "openssl" shared library.

I would use the "trace" (shell) command to find out what operating system
calls are executed during "FOO_login()", hoping that one of them
give me a clue.
