Because the 32-hex digit MDK is central to payment security, it must be handled according to strict industry regulations, such as PCI-DSS (Payment Card Industry Data Security Standard).

Use the provided terminal to input the key parts into your HSM key pairs generator.

A 32-hex-digit string represents of entropy ($32 \times 4 \text bits = 128 \text bits$). This is the standard length for the AES-128 algorithm, which has largely replaced the legacy Triple DES (TDES) algorithms in modern Point of Sale (POS) and PED (Pin Entry Device) infrastructure.
