Cryptographic Message Syntax
The Cryptographic Message Syntax (CMS) is the
IETF's standard for cryptographically protected messages. It can be used by cryptographic schemes and protocols to digitally sign, digest, authenticate or encrypt
any form of digital data.
CMS is based on the syntax of
RFC 5911
for updated ASN.1 modules conforming to ASN.1 2002).
The architecture of CMS is built around
PKIX working group
.
CMS is used as the key cryptographic component of many other cryptographic standards, such as
digital timestamping
protocol.
OpenSSL is open source software that can encrypt, decrypt, sign and verify, compress and uncompress CMS documents, using the openssl-cms command.
