The GNU Privacy Guard
GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP). GnuPG allows to encrypt and sign your data and communication, features a versatile key management system as well as access modules for all kinds of public key directories.
GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications. A wealth of frontend applications and libraries are available. Version 2 of GnuPG also provides support for S/MIME and Secure Shell (ssh).
GnuPG comes in three flavours:
- 2.1.15 is the modern version with support for ECC and many other new features,
- 2.0.30 is the stable version from the currently mostly used branch. This branch will reach end-of-life on 2017-12-31,
- and 1.4.21 is the classic portable version for use on very old platforms or to decrypt data created with PGP-2 keys.
