Criminals will always be able to easily encrypt messages, unless math is banned. Is the government going to ban every language that has simple encryption libraries? You can easily create your own private keys and encrypt your own messages with a few lines of Python code, and no one can break it. I don't think this is about child porn or terrorists at all. They're only the usual justification for wanting to snoop on everyone.
