Lib.rs

A hybrid post-quantum end-to-end encryption implementation using Securo:
HKDF-SHA256 hybrid key derivation from X25519 + Kyber-1024, SalsaBox (XSalsa20-Poly1305) bootstrap encryption, ChaCha20-Poly1305 session AEAD, Ed25519 signatures, Certificate (TLS 1.3) pinning (SPKI based), replay protection.

Server and Client included using Actix & Diesel Frameworks

Prelude

Read Securoserv and Securoclient for exact implementation of Securo.

Read this Example of Implementation 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.
