A new treaty between the US and UK will require social media companies like Facebook to hand over private messages but, contrary to recent reports, will not break end-to-end encryption or force them to add backdoors to their software.

That’s the upshot of a weekend of frantic commentary and debate over the CLOUD Act, which will likely be signed next month. The legislation is troubling, especially since it will legally require tech companies to hand over messages when requested by the authorities - an approach that has been wildly and consistently abused in the past - but it will not force those companies to provide them in a readable format.
