This document specifies the conventions for using Message
Authentication Code (MAC) encryption with the Cryptographic Message
Syntax (CMS) authenticated-enveloped-data content type.  This mirrors
the use of a MAC combined with an encryption algorithm that's already
employed in IPsec, Secure Socket Layer / Transport Layer Security
(SSL/TLS) and Secure SHell (SSH), which is widely supported in
existing crypto libraries and hardware and has been extensively
analysed by the crypto community.  [STANDARDS-TRACK]
