How personal identification numbers (PINs) are used

CCA allows your applications to generate PINs, to verify supplied PINs, and to translate PINs from one format or encryption key to another.

Many people are familiar with PINs, which are used to access an automated teller machine (ATM). From the system point of view, PINs are used primarily in financial networks to authenticate users. Typically, a user is assigned a PIN and enters the PIN at automated teller machines (ATMs) to gain access to his or her accounts. It is extremely important that the PIN be kept private so no one other than the account owner can use it.
