Warning: There are no guarantees for the security of these implementations. Use at your own risk.

Cryptographic functions implemented in Rust, with a simple API.

Currently contains: * HMAC with SHA2(256, 384, 512). * HKDF with the above HMAC options.

Usage

Include it in your Cargo.toml file: [dependencies] orion = ">=0.2.0" Use it like this: ``` extern crate orion use orion::{default, util};

// HMAC-SHA512 let key = util::genrandkey(64); let msg = "Some message.".as_bytes();

let expectedhmac = default::hmac(&key, msg); // Verifying an HMAC-SHA512 asserteq!(default::hmacvalidate(&expectedhmac, &key, &msg), true);

// HKDF-HMAC-SHA512 let salt = util::genrandkey(64); let data = "Some data.".asbytes(); let info = "Some info.".asbytes();

let hkdf = default::hkdf(&salt, data, info, 64); ```
