[Cryptography] Ex-CIA Joshua Schulte Describes His Data/Crypto Hiding Prowess

[John Young]

Can't find it now but I recall NSA dissolving remains of 
disintegrated disks in an acid pool until only a soft pudding is 
left. This done to reduce chances of meticulous reassembly or 
recovering data from hard fragments.

Sounds comparable to incinerating into ashes, unless ashes (or 
smoke/vapor) can be mined for data.

Side question: are cloud server facilities designed as SCIFs?

Schulte trial testimony describes the CIA building where he worked to 
be constructed of several layers of SCIF vaults, deeper the layer 
stronger the protection, physical and electronic. That building has 
been publicly identified as adjoining CIA University, nearby Dulles Airport.
