GnuPG is the GNU project’s complete and free implementation of the OpenPGP standard as defined by RFC4880 . 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.

GnuPG is Free Software (meaning that it respects your freedom). It can be freely used, modified and distributed under the terms of theGNU General Public License .

GnuPG comes in two flavours: 1.4.11 is the well known and portable standalone version, whereas 2.0.16 is the enhanced and somewhat harder to build version.

Some of its features include:

* Full OpenPGP implementation
* Full replacement of PGP
* Easy implementation of new algorithms using extension modules
* Does not use any patented algorithms
* Can be used as a filter program
* Better functionality than PGP and some security enhancements over PGP 2
* Decrypts and verifies PGP 5, 6 and 7 messages
* Supports ElGamal, DSA, RSA, AES, 3DES, Blowfish, Twofish, CAST5, MD5, SHA-1, RIPE-MD-160 and TIGER
* Integrated support for HKP keyservers
