John The Ripper (JtR) is a password cracking program.
Basic Usage
Dumb Brute Force
To brute force a password and to have John iterate through all the possible sequences:
john --incremental --stdout
This defaults to the incremental mode parameters. You can specify a different mode, say to use only integers:
john --incremental=digits --stdout
