APPENDIX C: TDES Key Installation
TDES Master Key Installation
Triple - Data Encryption Standard or TDES was designed as a way to strengthen the
security of the master key by upgrading from a 16 bit key to a 32 bit key. In addition to
the required software changes to support the TDES, the specification calls for a pin-pad
to encrypt any data sent between the keypad and the CPU. In this new configuration the
master keys are stored securely within the pin-pad, rather than the mainboard as done
previously.
Hardware Specification:
Hantle 1700w™ with PCI EPP (Encrypted Pin Pad)
Installation Procedure:
To access the Key Management menu from Host Setup, you’ll need to enter the Secure
Mode Password (parts 1 and 2). See page 3.6 for Secure Mode instructions.
Default Secure Mode password is:
Part #1 = 000000 / Part #2 = 000000
Access the Key Mode selections by entering
the operator function menu
[ENTER]+[CLEAR]+[CANCEL] – 1, 2, 3 (see
operator manual).

Setup

.
NOTE
: You must change the Secure Mode Password from default before any changes can
be made to Key Management, or enter any keys. Change the default passwords for Part
#1 and Part #2 and then completely exit the Operator Menu. Once you go back in and
use the new Secure Mode Passwords, you’ll be able to make changes or enter keys.
