CP Assist for Cryptographic Functions (CPACF) DES/TDES Enablement

CP Assist for Cryptographic Functions (CPACF) DES/TDES Enablement, feature 3863, provides for clear key DES and TDES instructions.

If you want to include cryptographic hardware, then feature 3863 is required.

If the CPACF feature is installed without the cryptographic hardware, you will not be able to:
  1. Set master keys.
  2. Initialize the PKDS or CKDS.
  3. Store keys in the PKDS.
