FYI, the relevant instructions are documented in the z/Architecture

http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/dz9zr002

Check Chapter 7 for the instructions:
CHIPER MESSAGE (KM)
CHIPER MESSAGE WITH CHAINING (KMC)
COMPUTE INTERMEDIATE MESSAGE DIGEST (KIMD)
COMPUTE LAST MESSAGE DIGEST (KLMD)
COMPUTE MESSAGE AUTHENTICATION CODE (KMAC)
