## Prelude

**Read [Securoserv](https://github.com/louislafosse/securo/tree/main/securoserv) and [Securoclient](https://github.com/louislafosse/securo/tree/main/securoclient) for exact implementation of Securo.**

**Read this [Example of Implementation](https://github.com/louislafosse/securo/blob/main/securo/examples/authentication.rs) for a short and easy way to implement Securo.**

This crate provides the **cryptographic impl** for an authentication and communication system.
It implements a hybrid classical-post-quantum key exchange protocol (X25519 + Kyber-1024) with HKDF-SHA256 key derivation, SalsaBox bootstrap channel encryption, ChaCha20-Poly1305 session encryption, and certificate pinning to establish secure, authenticated connections between client and server.
