This skill implements a simplified version of the Signal Protocol, focusing on robust end-to-end encryption (E2EE) for messaging applications. It covers critical cryptographic components including X3DH key agreement, the Double Ratchet algorithm for continuous key management, and AES-256-GCM for message encryption. The implementation ensures forward secrecy, meaning that compromising a current key does not reveal past messages. Use this when designing, building, or evaluating the security architecture of a messaging service to guarantee that only communicating parties can read the messages.
