What encryption protocol does EXTRA SAFE use?

Asymmetric E2EE with device-generated key pairs. Applied by default to all message types – not optional, nor configurable.

EXTRA SAFE uses asymmetric (public-key) cryptography. Each user has a key pair – a public key and a private key – generated locally on their device at account creation. Messages are encrypted with the recipient's public key and can only be decrypted with the corresponding private key, which never leaves their device.

This model means the encryption isn't something you turn on. It's the architecture. Every message, voice note, and file goes through the same process automatically.
