Package: brutalist
brutalistbrutalistis a python3-based command line tool for all platforms that can be used to generate quick and large word lists from one or more sample passwords provided by the user.Use case:Let's say you come across an outdated password in an old credential dump, but the user has since updated their password (password) toP@$$w0rd123!.
If fed the wordpassword,brutalistcan generate up to a few million unique custom combinations for that specific word.brutalistuses various methods of leet speak substitution, as well as other common special character substitutions, suffixes, and special character additions -- all while keeping the order of the original characters in the password.Notes:Running without the--limit-special,--limit-numbers, or--limitoptions decreases the number of results to something manageable.Running with the--leetoption increases the number of results exponentially to something quite large.The time it takes to return the results depends on the initial password length.Install from PyPI:pip3 install --upgrade brutalistInstall via Homebrew on MacOS:brew install phx/brutalist/brutalistInstall via Git:git clone https://github.com/phx/brutalistcd brutalistsudo cp brutalist /usr/local/bin/You can just as easily execute it where it stands or manually copy it elsewhere in your$PATH.Run:Usage: brutalist <[password] | -p [password] | -i [input file]> <[extended options]>

Options:
       [no params]                             takes input from stdin.
       [string]                                first argument is used as password.
       -p | --password                         second argument is used as password.
       -i | -f | --file [input file]           file is used as input.

Extended Options:
       -c | --limit-special | --limit-chars    limits special characters to '!@#$%*-+_'
       -n | --limit-numbers                    only includes common 1 and 2 digit suffixes + special
       -l | --limit                            limits both 3 digit numbers and special characters
            --leet                             includes all leet speak combinations (will increase size)Examplesstdinfrom pipe,stdoutto a file:cat small_list.txt | brutalist > huge_list.txtstdinfrom input redirection,stdoutto a file:brutalist < small_list.txt > huge_list.txtinput file as argument, write to both file andstdout:brutalist -f /path/to/small_list.txt | tee huge_list.txtRuntime samples for using the password example "password":---------------------------------------------------------
