We know that Lavabit was forced to shut its doors after NSA whistleblower Edward Snowden blew the lid on the NSA PRISM system, but now it looks like more of the story is finally leaking out, and it's quite bad.
According to court documents acquired by Wired, the FBI had served Lavabit with an order requiring it to hand over Snowden's encryption keys, helping the FBI install a device that would collect metadata from Snowden's e-mail connections. Lavabit refused, but did at one stage provide SSL keys to the FBI, printing them on 11 pages of 4pt type.
This eventuated in Lavabit being threatened with criminal contempt charges and fines. Lavabit's founder, Ladar Levison decided to close up shop after this, as you can imagine. This news helps us better understand why Lavabit decided to go dark, but what I don't understand is that Snowden revealed the NSA's PRISM system captured virtually everything, so why couldn't it use its own system to their advantage?
