The IBM CPACF Enablement crypto feature
The IBM Central Processor Assist for Cryptographic Functions (CPACF) feature, IBM Z feature code 3863, provides hardware acceleration for 290-960 MB/sec bulk encryption rate, AES (128, 192, 256 bit), DES (DEA, TDEA2, TDEA3), SHA-1 (160 bit), and SHA-2 (224, 256, 384, 512 bit).
The IBM Cryptographic Coprocessor Facility (CCF)
The Cryptographic Coprocessor Facility (CCF) is an optional hardware feature that provides high-performance cryptographic capabilities for z/VM®, including DES, Triple-DES, RSA, and various finance-industry-specific cryptographic services. IBM zSeries servers, except the zSeries 990, offer the CCF feature.
