On July 23, in a keynote address at the International Conference on Cyber Security at Fordham University, US Attorney General William Barr took up a banner that the Justice Department and Federal Bureau of Investigation have been waving for over a decade: the call for what former FBI director James Comey had referred to as a "golden key."

Citing the threat posed by violent criminals using encryption to hide their activities from law enforcement, Barr said that information security "should not come at the expense of making us more vulnerable in the real world." He claimed that this is what is happening today.
