e2encrypt by Karlo

A browser extension that encrypts and decrypts messages client side wherever you already talk: Instant messaging, email and social media. It has no idea where it's running, and doesn't need to. No extension network requests of any kind.

Features:
- Works everywhere already, on purpose. No per-site integration, no plugin for your chat app; paste ciphertext anywhere, it's just text.
- No account, no server. Peers exchange public keys directly with each other; there's nothing in between to trust or breach.
- Group chat, built on the same mechanism as a 1:1 message — you decide exactly who you write to.
- Fingerprint verification — catch a substituted key before you trust it.
Identity backup, offered once at creation, and then non-recoverable.
- Per-site auto-decrypt, opt-in, always re-lockable with one click.
- Zero telemetry. Nothing phones anywhere, ever
