24 alternatives to Differential Fuzzing of Cryptographic Libraries
Cryptofuzz Cryptofuzz is a project that fuzzes cryptographic libraries and compares their output in order to find implementation discrepancies. It’s quite effective and has already found a lo…
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Differential Fuzzing of Cryptographic Libraries launched in 2019; newer entries below may have overtaken it.

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 :)

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…

I recently dipped my toes into bug bounty hunting and finding security flaws in web applications. As a friend of UNIX shells I was building a repertoire of command line tools to make and analyze HTTP requests. Fortunately there are already many suitable tools like curl, jq, different fuzzers and some really nice tools for specific tasks by Tom Hudson [1]. However, I disliked that the existing fuzzers were monoliths where I had no easy way of creating custom behavior or analyses. They commonly do a multitude of things: Create multiple requests using one or more wordlist, sending the request,…

I wanted a safer alternative to RegExp for TypeScript that uses a linear-time engine, so I built Regolith. Why: Many CVEs happen because TypeScript libraries are vulnerable to Regular Expression Denial of Service attacks. I learned about this problem while doing undergraduate research and found that languages like Rust have built-in protection but languages like JavaScript, TypeScript, and Python do not. This library attempts to mitigate these vulnerabilities for TypeScript and JavaScript. How: Regolith uses Rust's Regex library under the hood to prevent ReDoS attacks. The Rust Regex library…

I've created cppmatch, a lightweight, header-only C++ library that brings Rust-inspired pattern matching and error handling to C++. It tries to imitate the functionality of the questionmark (?) operator in C++ by using a macro that uses the gcc extension https://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html This allows to create exceptionless code with non-intrusive error-as-value that unlike Exceptions, makes it clear which kinds of error a function can generate and forces you to handle (or ignore) them. The ? operator translates to *expect* To handle the errors I…

I’ve been experimenting with structured logic as a way to frame search spaces — not in an academic way, just as a personal project. I wanted to know: what happens if you initialize a brute-force run with a simple equality like xy = x / y? Not as a filter, just as a logical ignition point. I used AES-256-CBC encrypted files with UUID passwords and tested against a 1 million UUID space. It cracked it in under 40 seconds. Then I scaled it to a 1 billion UUID range, and it still found the key without issue. This isn’t a crypto tool, and I’m not trying to solve any cryptographic problems.…
