Even if law enforcement can get a warrant, unless there’s a backdoor in the encryption then the data stays private. That’s the whole point of encryption.

The fundamental problem is law enforcement feeling entitled to snoop on private communications with a warrant vs the inherent security flaw with making a backdoor in encrypted communications. The backdoor will eventually get exploited, either by reverse engineering/tinkering or someone leaking keys, and then encryption becomes useless. The only way encryption works is if the data can only be decrypted by one key.

Anyone else remember when TSA published a picture of the master key set for TSA approved luggage locks and people had modeled and printed replicas within hours?
