v1.0.0 – Post-Quantum Secure Channel (Kyber512 + AEAD)

Initial Stable Release – v1.0.0

This release marks the first stable API for QuantumCryptLib.

QuantumCryptLib provides a post-quantum secure communication building block
using Kyber512 (NIST-selected KEM) for key establishment and
AEAD (ChaCha20-Poly1305) for authenticated encryption.

Features

• Stable Kyber512 KEM API
• Shared secret establishment
• AEAD-based data encryption
• End-to-end secure channel example
• Integration tests covering multiple handshake cycles
• Rust 2021 edition

Cryptographic Design

Kyber is used only for key encapsulation, not for direct data encryption.
Application data is protected using AEAD, following industry best practices
for post-quantum migration.

API Stability

The public API introduced in v1.0.0 is considered stable.
Future v1.x releases will be backward compatible.

Planned Enhancements

• HKDF-based key derivation
• Hybrid classical + post-quantum mode
• Secret zeroization
• no_std support
