GLOME - Generic Low-Overhead Message Exchange

GLOME is a lightweight message authentication protocol based on X25519 keys and HMAC-SHA256. See https://github.com/google/glome for details on the protocol, usage patterns and implementations in other languages.

The Rust implementation of GLOME works with its own [PrivateKey] and [PublicKey] traits to support more than one backing cryptography crate. It aims to provide implementations for the crates most commonly used, which can be activated with the corresponding crate feature. The default and recommended setting is to use [x25519_dalek]. Implementations should be verified with the test vectors in the tests module.
