Transfer PIN Block -
(for Packet 76)
DUKPT Packet 71
Length:
DUKPT Packet 71
Example:
DUKPT Packet 71
Length:
Response packet to packet 76, request for PIN. The IPP encrypts the formatted
clear-text PIN block and sends the cipher-text PIN block to the master device.
(refer to the VISA PIN Processing and Data Authentication specification,
International version 1.0)
Packet 71 has a different packet format and meaning than the response PIN block
71 in MS. This is for compatibility with existing third parties (for example, Racal) to
initialize the DUKPT key.
