Dammit
Doesn't encrypt, mostly because 2 years behind bars just for losing/forgetting the key is much too harsh.
Also knowing my bad luck with computers I'd end up locking myself out of the data because its hard enough to remember a 22 digit alphanumeric let alone a 4096 bit D-H key.
Just gotta make that data quantum proof already :-)
That said, what if the incriminating data they "found" was planted, and the individuals involved just appeared to cooperate, leaking just enough information to sound convincing?
