The Certificate Management over CMS (CMC) is an Internet Standard published by the IETF, defining transport mechanisms for the Cryptographic Message Syntax (CMS). It is defined in , its transport mechanisms in .
Similarly to the Certificate Management Protocol (CMP), it can be used for obtaining X.509 digital certificates in a public key infrastructure (PKI).
CMS is one of two protocols utilizing the Certificate Request Message Format (CRMF), described in , with the other protocol being CMP.
The Enrollment over Secure Transport (EST) protocol, described in , can be seen as a profile of CMC for use in provisioning certificates to end entities. As such, EST can play a similar role to SCEP.
