RustCrypto: Cryptographic Message Syntax (CMS)
Pure Rust implementation of the Cryptographic Message Syntax (CMS) as described in RFC 5652, RFC 5911, and in RFC 3274.
About
Cryptographic Message Syntax (CMS) is an IETF standard for encrypted messages, and can be used to sign and/or encrypt data. It uses a certificate-based architecture for authenticating principals who can exchange encrypted and/or signed messages.
CMS is based on the syntax of PKCS #7, itself based on the Privacy-Enhanced Mail (PEM) standard.
It's used in many cryptographic standards, such as S/MIME, PKCS#12 and the RFC 3161 digital timestamping protocol.
