Abstract: Many crypto systems, such as Atalla (tm), provide the ability to compute a value for a DES cryptographic key that can be used to verify whether the key value was entered properly at another location. ICSF does not have this ability as a utility function. This sample application provides ISPF panels that can be used to specify a label of existing key in the CKDS and display the key check value, also called check digits, for the key value. Also supports clear DES (CLRDES) and AES (CLRAES) keys.
