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 you to encrypt and sign your data
and communications; it features a versatile key management system, along with
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.
GnuPG also provides support for S/MIME and Secure Shell (ssh).

Since its introduction in 1997, 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 .

The current version of GnuPG is 2.4.5. See the download page for other
maintained versions.

Gpg4win is a Windows version of GnuPG featuring a context menu tool, a crypto
manager, and an Outlook plugin to send and receive standard PGP/MIME mails. The
current version of Gpg4win is 4.3.1.


RECONQUER YOUR PRIVACY

> Arguing that you don't care about the right to privacy because you have
> nothing to hide is no different from saying you don't care about free speech
> because you have nothing to say. – Edward Snowden

Using encryption helps to protect your privacy and the privacy of the people you
communicate with. Encryption makes life difficult for bulk surveillance systems.
GnuPG is one of the tools that Snowden used to uncover the secrets of the NSA.

Please visit the Email Self-Defense site to learn how and why you should use
GnuPG for your electronic communication.
