## 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**

This crate provides the **cryptographic Impl** for an authentication and communication system.
It implements a hybrid classical-post-quantum key exchange protocol, session encryption, and certificate pinning to establish secure, authenticated connections between client and server.
