ISO 9564 PIN Block details

First, enter PIN in ISO 9564 PIN Block. Next, review PIN block (cleartext), PIN field, and PAN field. Additionally, ISO 9564 PIN Block uses 3 input fields and 3 output blocks so the result is easy to scan and copy.

Builds the cleartext PIN block exactly as defined by ISO 9564-1: format 0/3 XORs the PIN field against the PAN field; format 1 uses random padding with no PAN. The output is the 16-hex-digit cleartext block; the same value you'd encrypt under a PIN encryption key before sending it to a HSM. No actual encryption is performed and nothing is sent over the network.
