Majik Message is a private post-quantum secure messaging platform that demonstrates the power of the Majik Key. Majik Message uses cryptographic identity instead of emails or phone numbers. Accounts are derived from a 12-word seed phrase, generating X25519 and ML-KEM-768 post-quantum keypairs. Messages are encrypted end-to-end with hybrid cryptography (ML-KEM-768 + X25519 + AES-256-GCM) and private keys secured via Argon2id. Offline, users can encrypt/decrypt portable ~*$MJKMSG: strings for any channel. Real-time chats support expiring messages, groups up to 25, GIFs, and emoji reactions. Threads provide tamper-proof, auditable chains with collaborative deletion. Multi-account and cross-platform support includes a Chrome extension and local contact directory. Ideal for professionals and privacy-conscious users needing mathematically guaranteed security.
