An encapsulation syntax (RFC 3852) for digital signatures, hashes, and encryption of arbitrary messages. Tutorial: CMS derives from PKCS 7. CMS values are specified with ASN.1 and use BER encoding. The syntax permits multiple encapsulation with nesting, permits arbitrary attributes to be signed along with message content, and supports a variety of architectures for digital certificate based key management.
