That's how long it took the FBI to find a way into a San Bernardino shooter's iPhone and successfully exploit it without Apple's help. So while that particular case appears to be over, the encryption war is not. If anything, it is more urgent than ever.

The standoff over Syed Rizwan Farook's iPhone 5C didn't set any legal precedents, but it reminded anyone with the slightest interest in the encryption debate that the stakes are real, and immediate. More importantly, it pushed the issue into the mainstream, making it abundantly clear to everyone that their phones and other devices can provide tremendous privacy.

Almost everyone knows about encryption now. And everyone's moving quickly to shape its future.
