Similarity digest hashing algorithms in Rust with Python bindings

similarity-hash-rs

This library implements similarity digest hashing algorithms in rust and exposes ffi bindings for python3.

Status

Supported algorithms include:

• ssdeep

This is a work in progress. I'd like to include these algorithms in future work:

• TLSH
• sdhash
• LZJD

I don't currently have this repo configured to publish to crates.io or pypi.

Example

use fuzzy::ssdeep::*;

let digest = Hash::hash("The quick brown fox jumps over the lazy dog");

let digest_b = Hash::hash_from_file("/path/to/sample.exe");

let score = Hash::compare(&digest, &digest_b);

See the README in python/ for python3 usage.

About

This project started out as a exercise to learn rust and ffi in python. All comments or PRs for improvements are welcome!
