It's been two years since the FBI and Apple got into a giant fight over encryption following the San Bernardino shooting, when the government had the shooter's iPhone, but not the password needed to unlock it, so it asked Apple to create a way inside.

What's most surprising is how little has changed since then. The encryption debate remains unsettled, with tech companies largely opposed and some law enforcement agencies still making the case to have a backdoor.

The case for strong encryption: Those partial to the tech companies' arguments will note that cyberattacks and hacking incidents have become even more common, with encryption serving as a valuable way to protect individuals' personal information.

The case for backdoors: Criminals are doing bad stuff and when devices are strongly encrypted they can do it in what amounts to the perfect dark alley, completely hidden from public view.

What's next: The issue could well come up again, with deputy attorney general Rod Rosenstein a passionate voice for what he calls “responsible encryption” — that is, encryption necessary to protect consumers’ information balanced with the ability of law enforcement to access that information with a court order.

Critics warn that such tools will inevitably fall into the hands of both hackers and repressive governments.

Dig deeper: Here's a Time magazine story from March 2016 that took a deep dive into the issue and included an interview with, among others, Apple CEO Tim Cook.
