Enumcrt is a python tool designed to enumerate subdomains of websites using CRTSH.The traffic sent to enumcrt.py gets reflected in the website crtsh.CRTSH is a Certificate Transparency (CT) website which is used to perform a Certificate Search. This simple python tool scrapes the website and loads all subdomain obtain as result.

While enumerating subdomains of certain sites like (Google,Yahoo...) the tool may not respond.This is due the slow response from the CRTSH site and hence enumeration of huge list of domain is not possible.Even though the tool can easily crawl up to 2000+ URLs if available.

This requires Python 2.7 and We will soon release an update which supports Python 3.x

git clone https://github.com/Tibinsunny/enumcrt.git

Enumcrt depends on the json, urllib, and argparse python modules.

For installation on windows:

c:\python27\python.exe -m pip install -r requirements.txt

enumcrt.py -u example.com This lists out subdomain

enumcrt.py -u example.com -o test.txt This stores entire result to test.txt

This is a beta version.I hope you guys can help me in triggering bugs in the tool.Please do report bugs to [email protected].

Happy Hacking !!!
