This tool will help you understand how input is transformed on a system, which can help you craft better payloads.

Example: if you notice that a server responds with c1aa46d751f1ffa58481418667134109ac5f573c when you give in test, this tool will immediately tell you that it’s stringReverse(sha1(md5(md5("test")))).

This tool can be used at https://transformations.jobertabma.nl/

git clone https://github.com/jobertabma/transformations

docker build --tag transformations .
docker run -d -p 8080:80 transformations

You can then access the tool at http://localhost:8080/.
