PROGRAM:

NAME

psk-crack - Crack IKE Aggressive Mode Pre-Shared Keys

SYNOPSIS

psk-crack [options] <psk-parameters-file>

<psk-parameters-file> is a file containing the parameters for the pre-shared key cracking
process in the format generated by ike-scan with the --pskcrack (-P) option. This file
can contain one or more entries. For multiple entries, each one must be on a separate
line.

The program can crack either MD5 or SHA1-based hashes. The type of hash is automatically
determined from the length of the hash (16 bytes for MD5 or 20 bytes for SHA1). Each
entry in the <psk-parameters-file> is handled separately, so it is possible to crack a
mixture of MD5 and SHA1 hashes.

psk-crack can also crack the proprietary hash format used by Nortel Contivity / VPN Router
systems. When cracking Nortel format hashes, you need to specify the username of the hash
that you are cracking with the --norteluser (-u) option. When cracking Nortel format
hashes, you can only crack one hash at a time.

By default, psk-crack will perform dictionary cracking using the default dictionary. The
dictionary can be changed with the --dictionary (-d) option, or brute-force cracking can
be selected with the --bruteforce (-B) option.

DESCRIPTION

psk-crack attempts to crack IKE Aggressive Mode pre-shared keys that have previously been
gathered using ike-scan with the --pskcrack option.

psk-crack can operate in two different modes:

1) Dictionary cracking mode: this is the default mode in which psk-crack tries each
candidate word from the dictionary file in turn until it finds a match, or all the
words in the dictionary have been tried.

2) Brute-force cracking mode: in this mode, psk-crack tries all possible combinations
of a specified character set up to a given length.

OPTIONS

--help or -h
Display this usage message and exit.

--version or -V
Display program version and exit.

--verbose or -v
Display verbose progress messages.

--dictionary=<f> or -d <f>
Set dictionary file to <f>. The default is /usr/local/share/ike-scan/psk-crack-
dictionary.

--norteluser=<u> or -u <u>
Specify the username for Nortel Contivity cracking. This option is required when
cracking pre-shared keys on Nortel Contivity / VPN Router systems. These systems
use a proprietary method to calculate the hash that includes the username. This
option is only needed when cracking Nortel format hashes, and should not be used
for standard format hashes.

--bruteforce=<n> or -B <n>
Select bruteforce cracking up to <n> characters.

--charset=<s> or -c <s>
Set bruteforce character set to <s> Default is
"0123456789abcdefghijklmnopqrstuvwxyz"
