CP Assist for Cryptographic Functions (CPACF)

CPACF is a set of cryptographic instructions providing improved performance. The servers support different algorithms:

• On all IBM Systems:
  • SHA-1 algorithm is available.
  • SHA-224, SHA-256, SHA-384, and SHA-512 algorithms are available.
  • AES, DES, and TDES algorithms for clear and protected keys.
• On IBM z15 and later:
  • ECC algorithm for P-256, P-384, P-521, C25519, and C448 for clear and protected keys are available.
• On IBM z14 and later:
  • SHA3-224, SHA3-256, SHA3-384, SHA3-512, SHAKE128, and SHAKE256 algorithms are available.
  • True random number generator is available.
