Command: |
Translate an Encrypted Decimalisation Table from Encryption under an LMK in Key Change Storage pair 18-19 variant 1, to a new LMK pair 18-19 variant 1. |
|
Notes: |
This command is provided to simplify the LMK conversion process for issuers or transaction processors who use a large number of decimalisation tables. The use of encrypted decimalisation tables is strongly recommended. By default the HSM is configured to expect encrypted decimalisation tables in PIN verification commands that use the IBM method. For backward compatibility the HSM may be configured to use plaintext decimalisation tables using Configure Security.
