RustCrypto: Argon2

Pure Rust implementation of the Argon2 password hashing function.

Documentation

About

Argon2 is a memory-hard key derivation function chosen as the winner of the Password Hashing Competition in July 2015.

It implements the following three algorithmic variants:

• Argon2d: maximizes resistance to GPU cracking attacks
• Argon2i: optimized to resist side-channel attacks
• Argon2id: (default) hybrid version combining both Argon2i and Argon2d

Support is provided for embedded (i.e. no_std) environments, including ones without alloc support.

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.
