libatbus-protocol-crypto

What problem does it solve?

Enables secure transport for libatbus by providing a robust cryptographic handshake (ECDH), algorithm negotiation, encryption of messages, and authenticated access token handling, ensuring trusted node communication.

Core Features & Use Cases

• End-to-end crypto handshake using X25519 and HKDF-SHA256 key derivation
• Protobuf-based message framing with optional compression and encryption
• Token-based authentication and signing for access control
• Testing patterns and cross-language vector support for crypto flows
• Configurable crypto and compression policies for runtime reloading

Quick Start

Instantiate two nodes, perform an X25519 handshake, and securely exchange a test message.
