If the users of bitcoin are primarily criminals, that is pretty much what the founders intended. Every middle class man of affairs and business commits three felonies a day. The paper presupposes that criminals are such horrible people that everything they touch turns to shit. My

Truecrypt supports an inner and outer encrypted volume, encryption hidden inside encryption, the intended usage being that you reveal the outer encrypted volume, and refuse to admit the existence of the inner hidden volume. To summarize the judgment: Plausibile deniability, or even not very

Surely the core of the ruling is that no one except the defendant knows for sure whether the key exists, knows whether there is an inner truecrypt volume or not. The cross examination of the forensics witness focused on that point. On 2012-02-25 1:25 PM, d...@geer.org wrote:
