crunch

Generates custom wordlists by length, charset and pattern.

Pattern-based wordlist generator. You give it the minimum and maximum length, the charset and, if needed, a template (`-t`) where `@` is a lowercase letter, `,` an uppercase one, `%` a digit and `^` a symbol. Its real use is not generating the whole space of a length (it grows explosively and will not fit on disk) but exploiting a **known rule**: if the company is known to use the name plus four digits, `crunch 12 12 -t Company%%%%` produces exactly those and nothing else.
