In plain words

Differential Fuzzing of Cryptographic Libraries is a testing tool for developers and security researchers who work with cryptographic code. It compares how different cryptographic libraries handle the same inputs to find inconsistencies and potential vulnerabilities. By automatically generating test cases and checking for discrepancies across implementations, it helps identify bugs that might be missed by standard testing methods. The tool is particularly useful for ensuring cryptographic software behaves correctly and consistently.

    This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

  • The HTTP Garden – A Parser Vulnerability Research Tool2024 · github.com · ▲75

    I wrote this tool during an internship at Narf Industries in 2023. It's a REPL that allows for quickly developing, testing, and fuzzing for HTTP request smuggling attack payloads. I started the internship having never worked with web servers, and have now found over 100 HTTP implementation bugs. I attribute this mostly to the ease of experimentation in the Garden. REPL-oriented fuzzing is just a really good interface for finding parsing bugs. It's pretty neat to able to run a differential fuzzer, categorize and display all the discovered discrepancies, then let a human pick through them and…
