Encrypted PIN Translate (CSNBPTR and CSNEPTR) z/OS Cryptographic Services ICSF Application Programmer's Guide SA22-7522-16 |
|
Use the encrypted PIN translate callable service to reencipher a PIN block from one PIN-encrypting key to another and, optionally, to change the PIN block format, such as the pad digit or sequence number. The unique-key-per-transaction key derivation for single and double-length keys is available for the encrypted PIN translate service. This support is available for the input_PIN_encrypting_key_identifier and the output_PIN_encrypting_key_identifier parameters for both REFORMAT and TRANSLAT process rules. The rule_array keyword determines which PIN key(s) are derived key(s). The encrypted PIN translate service can be used for unique-key-per-transaction key derivation. An enhanced PIN security mode, on PCICC, PCIXCC, CEX2C, and CEX3C, is available for formatting an encrypted PIN block into IBM 3621 format or IBM 3624 format. 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. No other PIN block consistency checking will occur. The enhanced PIN security mode also extracts 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. You must enable the 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. As with formatting an encrypted PIN block, no other PIN-block consistency checking will occur. An enhanced PIN security mode on a CEX3C is available to implement restrictions required by the ANSI X9.8 PIN standard. To enforce these restrictions, you must enable the following control points in the default role.
The callable service name for AMODE(64) invocation is CSNEPTR. |
