We're trying to validate ARQC and generate ARPC for Mastercard using Thales PayShield-9000 HSM for CVN 14. We get response Code 01 (ARQC/TC/AAC/MPVV verification failure) and tried different combination for KW HSM command but still gets the same result. In KW Command host has to send Transaction Data and we doubt there has to be a issue in those data, also couldn't find any reference on how to send transaction data to the HSM. Below You can find some sample data that we already used on this and if you can point out any issue in those that would be a great help.
