Cryptographic Message Syntax
Lambert M. SurhoneISBN: 978-6-1324-9971-4;
s standard for cryptographically protected messages. It can be used to digitally sign, digest, authenticate or encrypt any form of digital data. CMS is based on the syntax of PKCS#7, which in turn is based on the Privacy-Enhanced Mail standard. The newest version of CMS (as of 2009[update]) is specified in RFC 5652 (but see also RFC 5911 for updated ASN.1 modules conforming to ASN.1 2002). The architecture of CMS is built around certificate-based key management, such as the profile defined by the PKIX working group. CMS is used as the key cryptographic component of many other cryptographic standards, such as S/MIME, PKCS#12 and the RFC 3161 Digital timestamping protocol.
