Encrypted PIN Verify (CSNBPVR and CSNEPVR) z/OS Cryptographic Services ICSF Application Programmer's Guide SA22-7522-16 |
|
Use the Encrypted PIN verify callable service to verify that one of these customer selected trial PINs is valid:
The unique-key-par-transaction key derivation for single and double-length keys is available for the input_PIN_encrypting_key_identifier parameter. An enhanced PIN security mode, on PCICC, PCIXCC, CEX2C, and CEX3C, is available for extracting PINs from encrypted PIN blocks. This mode only applies when specifying a PIN-extraction method for an IBM 3621 or an IBM 3624 PIN-block. To do this, you must enable the PTR Enhanced PIN Security access control point in the default role. When activated, this mode limits checking of the PIN to decimal digits and a PIN length minimum of 4 is enforced. No other PIN-block consistency checking will occur. The callable service name for AMODE(64) invocation is CSNEPVR. |
