(RIPEM) A (not yet complete, but useful)
implementation of
Privacy Enhanced Mail (PEM). RIPEM allows
your
electronic mail to have the four security facilities
provided by PEM: disclosure protection (optional),
originator authenticity, message
integrity measures and
non-repudiation of origin (always).
RIPEM was written primarily by Mark Riordan
<mrr@scss3.cl.msu.edu>. Most of the code is in the
public domain, except for the
RSA routines, which are a library
called RSAREF licensed from RSA Data Security, Inc.
The current (November 1993) version of RIPEM is 1.1a; the
current version of the
Macintosh port of RIPEM is 0.8b1.
