Web14 feb. 2024 · When the card reader pauses to obtain the user's PIN, the reader must send the card number (PAN) to the PIN pad along with a KSN. The PIN pad uses the KSN to derive a one-time PIN key. The PAN is then combined with the PIN (using XOR), and the combination (called a "PIN block") is encrypted with the one-time key before being sent … This algorithm was found in Annex A, section 3 on pages 50-54 * of the ANSI X9.24-1:2009 document. * * @param ipek The Initial PIN Encryption Key. * @param ksn The Key Serial Number. * @return The Dukpt that corresponds to this combination ...
