# Fuzzing
Prost ships a few fuzz tests, using both libfuzzer and aflfuzz.
## afl
To run the afl fuzz tests, first install cargo-afl:
cargo install -f afl
Then build a fuzz target and run afl on it:
cd fuzz/afl/<target>/
cargo afl build --bin fuzz-target
cargo afl fuzz -i in -o out target/debug/fuzz-target
To reproduce a crash:
cd fuzz/afl/<target>/
cargo build --bin reproduce
cargo run --bin reproduce -- out/crashes/<crashfile>
## libfuzzer
