Cryptographic algorithms in pure Rust.

The main interface to these crates is the RustCrypto traits.

All crates are no-std compatible.

Minimum Rust version: 1.31.

[1] SIMD is available for builds with target-cpu/target-feature configured, but runtime CPU detection is not yet supported.

Many of the crates in this project include optimized SIMD implementations, enabled by default on x86-64 by the "simd" feature. The fastest implementation available for your hardware will be automatically selected at runtime, except in no-std builds.

For other hardware platforms, e.g. ARM: an alternative, portable SIMD backend based on the packed_simd crate is available for recent nightly Rust; you can enable it as "packed_simd".

If you'd prefer to minimize usage of unsafe code: disable the "simd" feature to switch to a generic implementation.
