Definition: OpenPGP is a standard for secure email messaging. OpenPGP messages offer sender authentication using digital signatures and can be encrypted using public key cryptography to protect privacy. Since OpenPGP builds on and extends MIME, OpenPGP messages inter-operate well with any standard-compliant email client, even if it does not support OpenPGP natively. OpenPGP messages also work well with HTML formatting and attachments, where old-style ASCII-armored PGP messages failed.

Also Known As: PGP/MIME, OpenPGP/MIME
