title: ZPK Encryption ISO format 9594-1 Format 0
body: <p>I need to integrate our IVR with ATM switch. In this case IVR needs to send pin block formed in ISO format 9594-1 Format 0 only (Zone pin key – Pin encryption). WE have Clear component - 1 ,2, &amp; 3 &amp; ZMK - Key check value. I need to know steps to generate PIN Block format 0 using ZPK encryption.  Also as I am beginner need to know the role played here of clear component &amp; ZMK . </p>
