Certificate Management over CMS


The Certificate Management over CMS is an Internet Standard published by the IETF, defining transport mechanisms for the Cryptographic Message Syntax. It is defined in RFC 5272, its transport mechanisms in RFC 5273. It is one of two protocols utilizing the Certificate Request Message Format, described in RFC 4211, with the other protocol being the Certificate Management Protocol.
The Enrollment over Secure Transport protocol, described in RFC 7030, is a profile of CMC for use in provisioning certificates to end entities. As such, EST can play a similar role to SCEP.
