Released	~1987

Privacy-Enhanced Mail (PEM) is a secure e-mail standard that was never widely used. It is probably most notable for the other formats that borrowed from it and usurped its name (see PEM).

Identification

A message using this format includes a line that reads "-----BEGIN PRIVACY-ENHANCED MESSAGE-----".

For versions of the format prior to RFC 1421, the line reads "-----PRIVACY-ENHANCED MESSAGE BOUNDARY-----".
