Answers 'how do you get keys to login elsewhere' — both mechanisms, Signal/WhatsApp style: Server: - migration 0002: key_backups (recovery blobs) + provisions (QR relay), ciphertext only - routes/backup.js: POST/GET /api/backup, /backup/exists; provision new/get/complete - routes/keys.js: POST /api/keys/reset — atomically wipe stale prekeys + install fresh (fixes Bad MAC: restore regenerates prekey IDs that INSERT-OR-IGNORE kept stale) Crypto (crypto.js): - exportIdentityBlob/importIdentityBlob (identity travels only encrypted) - generateRecoveryCode (120-bit Crockford base32) + encrypt/decryptWithCode (PBKDF2 250k) - ephemeral ECDH (P-256) encrypt/decrypt for QR transfer Client (app.js): account-menu 'Set up recovery code' + 'Link a device' (camera scan via BarcodeDetector or paste); auth-screen 'Restore with recovery code' + 'Link from another device' (shows QR + code, polls, restores). Vendored qrcode-generator. All verified live end-to-end (3-process isolated-store integration tests): restore-from-code and QR-link both let a fresh device receive + decrypt messages.
