//! A usable pure-Rust cryptography library.
//!
//! ## Authenticated secret-key encryption
//! [`orion::aead`] offers authenticated secret-key encryption using
//! XChaCha20Poly1305.
//!
//! ## Password hashing and verification
//! [`orion::pwhash`] offers password hashing and verification using Argon2i.
//!
//! ## Key derivation
//! [`orion::kdf`] offers key derivation using Argon2i.
//!
//! ## Message authentication
//! [`orion::auth`] offers message authentication and verification using BLAKE2b.
//!
//! ## Hashing
//! [`orion::hash`] offers hashing using BLAKE2b.
//!
//! ### A note on `no_std`:
//! When orion is used in a `no_std` context, the high-level API is not available, since it relies on access to the systems random number generator.
//!
//! More information about orion is available in the [wiki](https://github.com/brycx/orion/wiki).
