Raymond Lau
June 23, 1993
This prerelease version of RIPEM Mac is available for public beta testing.
RIPEM Mac is a public key based cryptosystem aimed at
providing privacy and authentication capabilities for email
users. RIPEM Mac offers encryption (for privacy) and
authentication (or digital signatures for origin verification) using a hybrid RSA/DES approach as specified by the Internet Privacy Enhanced Mail (PEM) standard. Also supported is an extended triple DES encryption mode for extra security.
RIPEM Mac is compatible with the emerging Internet PEM
standard, including support for public key certificates
providing interoperability with various PEM implementations
such as TIS/PEM and COST PEM available for many platforms.
RIPEM Mac supports direct encryption/decryption from within
BBEdit via BBEdit extensions and from within most text editors and mailer programs via QuicKeys and the clipboard. Although oriented towards the protection of electronic mail, RIPEM Mac supports file encryption as well.
RIPEM Mac is format compatible with Mark Riordan's
RIPEM, providing cross-platform compatibility with many
Mach, Convex) and MS-DOS platforms for which RIPEM is
available.
RIPEM Mac is licensed to you free of charge for
non-commercial purposes. Please see the license agreement
