Comment Re:Encryption will be banned.. (Score 1) 92
It is not enforceable in the abstract sense - people can write their own encryption software at any time of course.
But it is very enforceable in the practical sense for about 99% of the population. First, the number of people who can write secure encryption apps is small. Even using standard algorithms and toolkits it is very difficult to implement securely end to end, especially if you have to assume your adversary has physical access to the device (i.e. a phone confiscated in an arrest). I don't find it at all unlikely that with a phone in their possession the police were able to break this particular app.
Distribution of the app is the more practical challenge. Get secure encryption banned/regulated, and it disappears from the Google and Apple app stores, disappears from github and other repositories, etc. That alone makes it inaccessible to anyone that isn't working hard to get it, since you need to jailbreak a phone and find something on the dark web. Not an effective deterrent to someone willing to put in the time and effort, but it ups the degree of difficulty significantly, and a bunch of the people who need that level of security will never take the time to track it down.
