11 hours ago
- Claim a universal handle to link socials and share public keys; private keys stay device-local.
- Post-quantum encryption (X25519, ML-KEM-768, XChaCha20-Poly1305) secures messages across existing apps.
- Two usage modes: handle-based (auto key discovery) or anonymous (manual invite trading).
- Ekko operates as a layer on top of messengers like Instagram, WhatsApp, Telegram; no new app required.
- Private key never leaves the device; only public keys are published via Ekko.
- Start using in browser, with keyboard integration planned next.
- Open source code ensures basic functionality remains free forever.
