Wayne,
I do not know anything about Diffie-Hellmann.
Never used it. Might want to ask the list instead.
If you use .cpp, don't forget to wrap your C stuff in
#ifdef __cplusplus
extern "C" {
#endif "
/* Your stuff */
#ifdef __cplusplus
}
#endif "
Otherwise you will get undefined externals at linking time,
since C fct translations are different from CPP fct translations.

The .LIB is the _import_library_ which tells other DLLs and EXEs about
the
definitions contained in the .DLL file. Don't include the DLL file in
your
project, instead include the LIB file.

There are only silly answers, no silly questions (or people that
might not have any time to answer) (Well, up to a certain point.
I once had a guy ask me how to use printf() while he was trying to
debug a ISAPI DLL for IIS4 <groan>.)
Cheers!
