# check-psk-crack-3 -- Shell script to test psk-crack for Nortel style hashes
#
# Author: Roy Hills
# Date: 19 November 2004
#
# This shell script checks that psk-crack works for Nortel Contivity MD5 and
# SHA1 based hashes. The Nortel contivity VPN client uses a proprietary
# authentication mechanism, based on Mamro's Pre-Shared Key Extensions for
# ISAKMP/Oakley.

TMPFILE=/tmp/ike-scan-test.$$.tmp
MD5PSK=/tmp/nortel-md5-psk.$$.tmp
SHA1PSK=/tmp/nortel-sha1-psk.$$.tmp
DICTFILE=/tmp/ike-dict-file.$$.tmp
# Create PSK parameter files with known pre-shared keys.
# These parameters were generated using ike-scan 1.8.4 and Nortel Contivity
# server software v6.00.310. In both cases, the username is "test", and the
# pre-shared key is "abc123"
