FormatFuzzer
FormatFuzzer is a framework for high-efficiency, high-quality generation and parsing of binary inputs.
It takes a binary template that describes the format of a binary input and generates an executable that produces and parses the given binary format.
From a binary template for GIF, for instance, FormatFuzzer produces a GIF generator - also known as GIF fuzzer.
Generators produced by FormatFuzzer are highly efficient, producing thousands of valid test inputs per second - in sharp contrast to mutation-based fuzzers, where the large majority of inputs is invalid. By default, FormatFuzzer operates in black-box settings, but can also integrate with AFL++ to produce valid inputs that also aim for maximum coverage.
FormatFuzzer is open source, available from the FormatFuzzer project page. Contributors are welcome!
