Bindiff

A fast, memory-safe function-level binary diffing tool written in Rust (Linux + Windows).

Features

• Parses ELF and PE (via goblin)
• Disassembles x86_64 using pure-Rust yaxpeax-x86
• Normalizes operands (REG/MEM/IMM) to reduce false deltas
• Computes BLAKE3 hash and SimHash per function
• Matches functions by name; classifies unchanged / modified / added / removed
• Generates JSON and HTML reports
• Parallel-ready and memory-safe by design

Note: Capstone integration and CFG-based graph matching can be added later as optional features.

Build

cargo build --release

Usage

# Diff two x86_64 binaries
bindiff ./old.bin ./new.bin -o result.json -H result.html

Roadmap

• Add optional capstone feature for more architectures
• Improve function discovery for stripped binaries
• CFG recovery and VF2 isomorphism-based matching
• String/call-reference signature matching
