You might want to notice that we've already import the "md5.c" and
"md5.h" files from GNULIB.  They can be found in CVS's "lib" directory.
 There is also an hmac-md5 module among other digest modules (md2, md4,
sha1, ???).

I would note that GNULIB now also has a "gc" ("generic crypto") module,
which looks like it wraps standard MD5 and HMAC-MD5, among other
digests.  I believe the idea of the gc module is that you set a
particular mode, then call all the digest functions identically,
otherwise.  If you want to support more than one type of password
digest, this may be the easiest way to go.

Cheers,

Derek
