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

There are two major flavours of GnuPG:

2.1.16 is the modern version with support for ECC and many other new features,
2.0.30 is the stable version from an often used branch. This branch will reach end-of-life on 2017-12-31.

Project Gpg4win provides a Windows version of the old GnuPG stable. It is nicely integrated into an installer and features several frontends as well as English and German manuals. A simple Windows installer for the modern version is available at our download page.

As of versions 2.0.26 and 1.4.18, GnuPG supports the following algorithms:

Pubkey: RSA, ElGamal, DSA
Cipher: IDEA (since versions 1.4.13 and 2.0.20), 3DES, CAST5, Blowfish, AES-128, AES-192, AES-256, Twofish, Camellia-128, -192 and -256 (since versions 1.4.10 and 2.0.12)
Hash: MD5, SHA-1, RIPEMD-160, SHA-256, SHA-384, SHA-512, SHA-224
Compression: Uncompressed, ZIP, ZLIB, BZIP2

More recent releases of GnuPG 2.x ("stable" and "modern" series) expose most cryptographic functions and algorithms Libgcrypt (its cryptographic library) provides, including support for elliptic curve cryptography (ECDSA, ECDH and EdDSA)[10] in the "modern" series (i.e. since GnuPG 2.1).
