How Does Work?
Key Exchange
On every new connection between our server and your device, encryption keys are exchanged with crystal-kyber-1024 post-quantum cryptographic key exchange mechanism
Message Encryption
After that, all information in-between is encrypted with another quantum resistant XChaCha20-Poly1305 cryptography
End-to-End Encryption
When you start a one-to-one or a group chat with anyone, another key is exchanged on top, but this time between yours and the other person's device. All the sent messages in the chat get automatically encrypted with the new End-To-End key
Password Protection
Every message's encryption key can be modified by a password. You can even use different passwords for every new message. Passwords can be 32 characters long.

We use post-quantum encryption with Kyber1024 for key exchange and XChaCha20-Poly1305 for message encryption. Both are resistant to attacks from quantum computers.
Only the people who you add or approve as contacts.
No, we have implemented measures to prevent screenshots and screen recordings within the app to protect your privacy.
No you can only send messages, voice messages, photos and files. We do not support voice or video calls yet but maybe we will in the future.
We envision evercrypted as a secure communication tool for legal and meaningful conversations. We don't want evercrypted to be used for illegal purposes and recorded video messages could potentially be misused in certain contexts. Also every file sent through evercrypted can be of maximum 50 MB in size for this reason.
