# A high-level view
## Why OpenPGP?
OpenPGP is an IETF-standardized set of cryptographic operations. OpenPGP defines mechanisms for authentication of cryptographic identities with a decentralized trust model.
## A very brief history
The OpenPGP standard has evolved over time, and remains under active development.

### Standardizing OpenPGP
While the original PGP software was developed as a commercial product, the owner at the time, "PGP Inc." started a standardization effort with the IETF in July 1997.
The resulting open standard was named [OpenPGP](https://en.wikipedia.org/wiki/Pretty_Good_Privacy#OpenPGP).
While the original PGP software was developed as a commercial product, the owner at the time, "PGP Inc." started a standardization effort with the IETF, first publishing [RFC 1991 "PGP Message Exchange Formats"](https://datatracker.ietf.org/doc/html/rfc1991) in August 1996.
The result of this early standardization work is [RFC 2440 "OpenPGP Message Format"](https://datatracker.ietf.org/doc/html/rfc2440), published November 1998. RFC 2440 describes OpenPGP version 3.
In July 1997, a process to produce an open standard under the then new name [OpenPGP](https://en.wikipedia.org/wiki/Pretty_Good_Privacy#OpenPGP) was started, resulting in [RFC 2440 "OpenPGP Message Format"](https://datatracker.ietf.org/doc/html/rfc2440), published November 1998. RFC 2440 describes OpenPGP version 3.
The name "OpenPGP" can be used freely by implementations (unlike the name "PGP", which is a [registered trademark](https://uspto.report/TM/74685229)).
