AKA: GnuPG

Acronym: Gnu Privacy Guard

A complete and Free Software replacement for the commercial PGP encryption tool for a wide variety of operating systems. Although the program itself is textmode only, user-friendly front-ends are available (see below).

Unlike PGP, it can be used without any restrictions by individuals and commercial entities alike because it does not use the patented IDEA algorithm.

PGP Compatibility

  • PGP users can disable the use of the IDEA algorithm in their options to make it fully compatible.
  • GPG users can install an IDEA plugin explained here.

GPG is an OpenPGP-compliant (RFC 2440]) application.
