OpenPGP: History & Standards

OpenPGP is an open standard that describes a message (file) format originally used by the Pretty Good Privacy (PGP) program, initially developed by Phil Zimmermann in 1991. A number of standard-track Request for Comment documents augment its functionality, one example being PGP/MIME which defines the use of OpenPGP in email via MIME. OpenPGP's encryption…
