Command: |
Translate a PIN and/or PIN length from encryption under the LMK pair held in “key change storage” to encryption under LMK pair 02-03. Also, translate the PIN length if a new value has been selected. |
|
Notes: |
The command can be used to translate the PIN length only. In this case, load the same LMKs to “key change storage” that are loaded as the current LMK. The PIN length is L2N for PIN encryption algorithm A, and L2H for PIN encryption algorithm B, as selected by the CS (Configure Security) console command. |
