# 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.
|
|
|
|
