One of the nasty coercive laws of the last few years has just taken a beating:
A Yank federal appeals court has ruled that being forced to decrypt your stuff is unconstitutional. Good for the J. Doe in question, who relied on TrueCrypt which is a pretty nice tool (open-source - but badly licenced, multi-platform, and it does plausible deniability).
The actual text of the ruling is also pretty interesting in its argumentation.
Now if only the powers that be in this place would scrap the Cybercrime Act 2001 No. 161, items 12 and 28...
