//! A pure-rust implementation of various cryptographic algorithms, which no dependencies
//! and no foreign code (specially C or assembly).
//!
//! Our goals is to support rust cryptography in various constrained environment like embedded devices and web assembly
//!
//! This is a fork of [Rust-Crypto by DaGenix](https://github.com/DaGenix/rust-crypto),
//! which we owe a debt of gratitude for starting some good quality pure rust implementations
//! of various cryptographic algorithms.
//!
//! Notable Differences with the original sources:
//!
//! * Maintained
//! * Extended ED25519 support for extended secret key (64 bytes) support
//! * Proper implementation of ChaChaPoly1305
//! * Many cryptographic algorithms removed: AES, Blowfish, Fortuna, RC4, RIPEMD160, Whirlpool, MD5, SHA1.
//!
//! As with everything cryptographic implementations, please make sure it suits your security requirements,
//! and review and audit before using.
//!
