psk-crack attempts to crack IKE Aggressive Mode pre-shared keys that have been previously 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.
