Riordan's Internet Privacy Enhanced Mail RIPEM <messaging> (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 <[email protected]>. 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. (1998-07-03)
