A systematic tour of the Me2eM cryptographic package: HKDF and domain separation, X3DH with mandatory OTK, channels with epoch rotation, envelopes for offline recipients, media encryption and password guard rails.
Step-by-step tutorial: deterministic identity from seed phrase, X3DH channel with offline recipient, per-message encryption with replay protection. Code for all steps — in the article.
A zero-trust-to-server messenger concept: identity without registration, stateless session verification, X3DH chats, epoch rotation of group keys, and the honest price of privacy.
A complete engineering guide to an architecture where the private key is never stored: a deterministic key tree, non-extractable CryptoKey, canonical X3DH.
Install a package, follow the quick start, and verify your first stateless session in minutes.
