RFC 4134 -- Examples of CMS objects and S/MIME messages

Top - Overview  - Basic Signed Content, DSS  - Multiple Signers 
- Private Keys  - Basic Signed Content, RSA  - Signing Using SKI 
- Enveloped-data  - Basic Signed Content, Detached Content  - SignedData with Attributes 
- Encrypted-data  - Fancier Signed Content  - SignedData with Certificates Only 
  - All RSA Signed Message  - S/MIME Messages 

Basic Signed Content, DSS
