Editing Privacy-Enhanced Mail (section)

{{short description|Family of file formats associated with RFC 1421}}
{{Security protocol}}
'''Privacy-Enhanced Mail''' ('''PEM''') is a [[de facto]] file format for storing and sending cryptographic [[Key (cryptography)|keys]], [[Public key certificate|certificates]], and other data, based on a set of 1993 [[Internet Engineering Task Force|IETF]] standards defining "privacy-enhanced mail." While the original standards were never broadly adopted and were supplanted by [[Pretty Good Privacy|PGP]] and [[S/MIME]], the textual encoding they defined became very popular. The PEM format was eventually formalized by the IETF in [[rfc:7468|RFC 7468]].<ref>{{cite journal |last=Johnson |first=Mike |date=1995-10-01 |title=Cryptology in Cyberspace |journal=Cryptologia |volume=19 |issue=4 |pages=392–396 |doi=10.1080/0161-119591884042 |issn=0161-1194 |s2cid=41770450}}</ref>
