Implementing End-to-End Encryption for Messaging Overview End-to-end encryption (E2EE) ensures that only the communicating parties can read messages, with no intermediary (including the server) able to decrypt them. This skill implements a simplified version of the Signal Protocol's Double Ratchet algorithm, using X25519 for key exchange, HKDF for key derivation, and AES-256-GCM for message encryption. When to Use - When deploying or configuring implementing end to end encryption for messaging capabilities in your environment - When establishing security controls aligned to compliance require…
