Privacy-Enhanced Mail (RFC 1421)
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).
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-----".
