Encryption and the safety code
Messages are encrypted on your device, and only you and the person you write to can read them.
KUVRT checks each contact's keys against its public key list by itself. "Contact info" shows "Checking encryption" at first, then "Encryption verified".
"Encryption not verified" means KUVRT could not confirm their keys recently, often because it was offline. Open the chat with a connection and it checks again.
To be sure, compare the safety code in person: 60 digits.
- Both of you tap the other's name at the top of the chat, then "Safety code".
- Read the digits out, or hold the screens side by side.
- If both show the same code, nobody is in between.
What this cannot do
- A matching code proves nobody is in between. It does not prove who is holding the other phone.
