WebThe Cryptographic Message Syntax ( CMS) is the IETF'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. WebAbstract. This document updates the "Cryptographic Message Syntax (CMS) Algorithms" (RFC 3370) and describes the conventions for using the SHAKE family of hash functions in the Cryptographic Message Syntax as one-way hash functions with the RSA Probabilistic Signature Scheme (RSASSA-PSS) and Elliptic Curve Digital Signature Algorithm (ECDSA).
