Veil

Veil adds end-to-end encryption to any web messenger — WhatsApp Web, Telegram Web, Facebook Messenger, or any chat that runs in your browser. The platform never sees your messages. Only encrypted text leaves your browser. HOW IT WORKS 1. One person clicks "Start Session" and an invite code is sent through the chat 2. The other person opens Veil, and the extension automatically detects the invite and replies 3. Both sides derive a shared secret — every message is now encrypted with AES-256-GCM before it enters the chat No extra apps. No sign-ups. Just install and go. SECURITY • Fresh ECDH P-256 key pairs generated per session • Shared secrets derived with HKDF • Messages encrypted with AES-256-GCM • Session fingerprint for manual verification • In-band and server-based verification to detect man-in-the-middle attacks • End-session signal wipes all keys on both sides simultaneously PRIVACY • No accounts — no email, no phone number, nothing • Keys exist in RAM only (chrome.storage.session) — close the browser and they're gone • No analytics, no telemetry, no data collection of any kind • Fully open source: https://github.com/KianAttar/veil WHAT VEIL CANNOT PROTECT Veil encrypts message content in transit and at rest on the platform's servers. It cannot protect against: • Device-level compromise (malware, spyware, keyloggers) • Physical access to an unlocked device • Metadata (who you talk to, when, how often) • Screenshots or screen recording SETUP First time on a site, click "Set up for this site" to teach Veil where the input box and send button are. After that, encryption is automatic. Supports English and Persian (فارسی). Website: https://veil.kiancode.dev Source: https://github.com/KianAttar/veil Support: support@kiancode.dev
