A more honest effort would have pushed 3DES for high security instead
of an RSA patented algorithm of still dubious merit. 40 bit keys can
be achieved easily for DES by the expedient of doing something like
exposing 16 of the bits. There is no good reason for anyone to use RSA
DSI proprietary conventional cipher algorithms.
