OpenPGP is the most widely used email encryption standard. It is defined by the OpenPGP Working Group of the Internet Engineering Task Force (IETF) as a Proposed Standard in RFC 4880. OpenPGP was originally derived from the PGP software, created by Phil Zimmermann.

Email encryption

Although OpenPGP’s main purpose is end-to-end encrypted email communication, it is also utilized for encrypted messaging and other use cases such as password managers.

For all operating systems

OpenPGP is available for all major platforms, such as Windows, Mac OS, GNU/Linux, Android, and iOS.

• GnuPG is a free implementation of OpenPGP. 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.
• PGP is the gold standard for encrypted communication and has been used by everyone from nuclear activists to criminals since its invention in 1991. While the execution is complex, the concept and usage is simple. This article shows how it works and how you can get started.

Standing the test of time

OpenPGP was standardized in 1997 and since then continuously improved. As far as we know, intelligence organizations aren’t able to break it.

Reconquer your privacy

Arguing that you don't care about the right to privacybecause you have nothing to hide is no different fromsaying you don't care about free speech because you havenothing to say. – Edward Snowden

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