shcheck - Security Header Check

PyPI Pypi Updated Output on Facebook

Check security headers on a target website

I did this tool to help me to check which security headers are enabled on certain websites.

The tool is very simple and it's the result of few minutes of coding.

It just check headers and print a report about which are enabled and which not

I think there is a lot to improve, and I will be grateful if somebody wants to help

How to run:

Pypi

pip3 install shcheck
shcheck.py https://insecurity.blog

Docker

First build your docker container using something like this:

docker build -t shcheck .

Then simply run your docker container using something like this where you specify which website you want to check headers on:

docker run -it --rm shcheck https://insecurity.blog

From source

git clone https://github.com/santoru/shcheck && cd shcheck
./shcheck.py https://insecurity.blog
