The CMS RFC (RFC 5652) specifies password based key derivation (in addition to 
asymmetric-key crypto key transport or agreement, and also a 
symmetric-cryptography key transport mechanism). See section 6.2.

It looks like password based key derivation wasn't in the original PKCS#7, but 
was introduced in a 2001 specification (RFC 3211) and was folded into the 2002 
revision of CMS (RFC 3369).
