About Alberich Companion

Encrypt and decrypt text in seconds – right in the browser, no extra tab. Alberich Companion is the slim add-on to the web app. Select text, open the side panel, or use the context menu – done. Daily keys as JSON, V3 hardened as .alb3cb2 (same as web/Android). Everything stays local on your device. Courier mode: on the online computer, ciphertext only (QR and letters). Encrypt and decrypt stay on the offline device – a content scan sees letter salad. Modern: format-3 monthly sheets (free end rotor, notches on the sheet). Telegram ALBV with a check group at the end (HMAC, not a second message key). Public demo under Info — not for real messages. Modern is an experimental rotor protocol, not an AES replacement. ✅ Modern mode only (full text, automatic message key, format-3 sheet) ✅ Courier on/off: machine or bridge only ✅ Plaintext stays isolated in the extension – with courier on it never touches this window ✅ No tracking, no ads, fully local ✅ Built for everyday use and #ChatcontrolByeBye Simple.
