Sets up cargo-fuzz for a Cargo-based Rust project: nightly toolchain, fuzz targets, structured inputs, sanitizers, coverage and reproducing crashes.

trailofbits/skills

Builds fuzzing dictionaries of keywords, magic bytes and tokens and wires them into libFuzzer, AFL++ or cargo-fuzz so fuzzers get past input validation.

trailofbits/skills

Patches checksums, hash checks, time-based seeds and other non-deterministic state out of fuzzing builds so the fuzzer reaches deeper code, with production behavior intact.
