question about encryption


Recommended Posts


just installed umurmur on my synology NAS, works fine.

There's just something caught my eyes I don't understand:

When connected to my server with my iPhone and the phone is locked, I get a push message from the Mumble app and I'm able to read the content.

By comparison to Threema, why/how is this possible? Threema (end to end encrypted mobile messenger) says, those previews are not technically feasible because of the encryption and the IOS restrictions.

Would be nice if someone can explain me the difference :-)

Mumble is still connected to the server in the background. It handles all notifications locally.

Other apps presumably have to use push notifications (which go through Apple) to do the same. And they don't want to compromise their security by handing your encrypted messages to Apple, unencrypted.
