The Clear PIN Encrypt callable service formats a PIN into one of these PIN block formats and encrypts the results. You can use this service to create an encrypted PIN block for transmission. With the RANDOM keyword, you can have the service generate random PIN numbers.

Note:

A clear PIN is a sensitive piece of information. Ensure that your application program and system design provide adequate protection for any clear PIN value.

An enhanced PIN security mode, on PCICC, PCIXCC, CEX2C, or 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 callable service name for AMODE(64) invocation is CSNECPE.
