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 1.57 or higher.

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