Crack Crack is a Unix password cracking program designed to allow system administrators to locate users who may have weak passwords vulnerable to a dictionary attack.
Crack began in 1990 when Alec Muffett, a Unix system administrator at the University of Wales Aberystwyth was trying to improve Dan Farmer's 'pwc' cracker in COPS and found that by re-engineering its memory management he got a noticeable performance increase. This led to a total rewrite which became "Crack v2.0" and further development to improve usability.
