RustCrypto: Balloon Hash

Pure Rust implementation of the Balloon password hashing function.

Documentation

About

This crate contains an implementation of the Balloon password hashing function as specified in the paper Balloon Hashing: A Memory-Hard Function Providing Provable Protection Against Sequential Attacks.

This algorithm is first practical password hashing function that provides:

• Memory hardness which is proven in the random-oracle model
• Password-independent access
• Performance which meets or exceeds the best heuristically secure password-hashing algorithms

Minimum Supported Rust Version

Rust 1.65 or higher.

Minimum supported Rust version can be changed in the future, but it will be done with a minor version bump.
