GNU Privacy Guard has been released.

In cryptography, encryption is the process of obscuring information to make it unreadable without special knowledge.

While encryption has been used to protect communications for centuries, only organizations and individuals with an extraordinary need for secrecy had made use of it.

In the mid-1970s, strong encryption emerged from the sole preserve of secretive government agencies into the public domain, and is now employed in protecting widely-used systems, such as Internet e-commerce, mobile telephone networks and bank automatic teller machines.

When email spam went out of control and email identity theft is order of the day, emails were encrypted too. There has been a lot of advancement in the email encryption over the years.

OpenPGP is the most widely used email encryption standard in the world. It is defined by the OpenPGP Working Group of the Internet Engineering Task Force. The OpenPGP standard was originally derived from PGP (Pretty Good Privacy), first created by Phil Zimmermann in 1991.

GnuPG has grown as an open-source implementation of the OpenPGP standard.
After a long phase of development as the 1.9 series, version 2.0 of the security-suite GNU Privacy Guard has been released.
