Fuzz2 - honggfuzz

This directory contains files pertaining to fuzz testing with the honggfuzz fuzzer.

We're trying this tool out alongside libfuzzer (covered in darkfi/fuzz/).

Comparison to libfuzzer

• Does not halt execution on crashes (can discover multiple crashes in one fuzzing session)
• Fewer memory issues (tool less likely to crash, easier to configure)
• Better UI

Install

cargo install honggfuzz

Usage

# Build targets from Cargo.toml [[bin]] section
cargo hfuzz build
# Run
cargo hfuzz run zkbinary-decode
