💀 Scuwl 💀

Simple custom wordlist generator

Scuwl (skull) is a Python CLI program that quickly and easily generates a wordlist from a webpage. The idea for Scuwl was inspired by the program Cewl. Scuwl defaults to a crawling depth of zero and most webpages return a wordlist in less than a second. Using a crawling depth of one generally takes a few minutes.

Scuwl is fast because it recursively scrapes websites asynchronously. Scuwl minimizes its memory footprint by processing HTML as it goes and updating the wordlist in memory as a set. By default Scuwl keeps unique words, three characters long and over, and removes all punctuation.

Note: Using a crawling depth of over one remains untested.

Features

  • Fast recursive asynchronous web requests using aiohttp
  • CLI options gives you control over the generated wordlist
  • Simple Python codebase (< 150 lines)
  • Low memory usage (~80MB)

Installation

  python -m pip install scuwl

Usage

$ scuwl -h
usage: scuwl.py [-h] [-d DEPTH] [-H HEADERS] [-m MIN_LENGTH] [-o OUTFILE]
                [-P PROXY] [-p] [-u USER_AGENT] [-v]

Examples

Generate wordlist and send to stdout

$ scuwl https://github.com/petebuffon/scuwl
topics
out
scuwl
2022
track
...

Generate wordlist and save as wordlist.txt

$ scuwl -o wordlist.txt https://github.com/petebuffon/scuwl
$ wc -l wordlist.txt
122 wordlist.txt

Keep punctuation

$ scuwl -p -o wordlist.txt https://github.com/petebuffon/scuwl
$ head wordlist.txt
customer
wait?
write
devops
user

Use a crawl depth of one (scrapes all links from input webpage)

$ scuwl -d 1 -o wordlist.txt https://github.com/petebuffon/scuwl
$ wc -l wordlist.txt
6326 wordlist.txt
