Clear PIN Generate Alternate (CSNBCPA)

Use the Clear PIN Generate Alternate verb to generate a clear VISA PVV (PIN validation value) from an input encrypted PIN block or to produce a 3624 offset from a customer-selected encrypted PIN. The PIN block can be encrypted under either an input PIN-encrypting key (IPINENC) or an output PIN-encrypting key (OPINENC). When the input encrypted PIN block is in ISO-4 format, the PIN-encrypting key is an AES PINPROT key.
