My GnuDIP application once used the unix crypt() witch I think is about
40bit. I recently swiched all my authentication algorithms to use a MD5
based scheme, so that other os's would be able to make a client application
easier. I am pretty sure the MD5 is a stronger (and more flexable)
encryption algorithm. It is also not restricted by any export laws that I
am aware of.
