Crunch is a wordlist generator where you can specify a standard character set or a character set you specify. crunch can generate all possible combinations and permutations.
Features

This project aims to be a wordlist mutator with hormones, which means that some
mutations will be applied to the result of the ones that have been already done,
resulting in something like:


corporation -> C0rp0r4t10n_2012

This software is usefull when applied to a few words, like company name and/or
domain name targeted or the usernames of the system administrators. You must
think that the number of wrds resulting of applying all mutations is exponential
: a 1 word input would generate an output of 1200 words; a 4 words input would
generate an output of 4800 words.

The actual mutations supported are:
* Case mutations (toUpper, toLower, FirstCharUpper, SwapCase)
* T0 l33t mutation
* Add Special Char mutation
* Append String of a predefined list
* Append Date

Some mutations are strange, and some of them have no sense applied together,
like *_strings and add_year, but is your decision, for that exists the
parameters xDDD

The mutations "prepend_string" is commented becouse IMHO have no sense xD and
is rare find passwords like this but feel free to uncommented it, and don't
forget uncomment it in mutator.h too

-f, --file [file]* File from read the words
-w, --word [word]* Word to mutate
-b, --basic         Only "case" and "l33t" mutations
