Viper is a standard unix password cracker, but instead of using a wordlist it will generate all the password combinations for the character sets and length you specify. New in this version is the ability to load and save from a progress file, define a minimum password length, and set the number of hours to run. Included in this package is the perl source, which shouldn't be a problem on a unix machine, but for win32 you will need to install the perl interpreters (ActivePerl @ http://www.activestate.com).
