Defendant must tell government his password

sohp writes: "Over at The Volokh Conspiracy, reports are out that the case of a man who invoked the 5th amendment when asked to supply the password to decrypt his hard drive to allow police to search for child pornography has a new development. A judge has overturned the original magistrate's decision allowing the defense and has ordered Sebastien Boucher to supply the prosecutors with a decrypted hard disk. Note that the order is not that he produce the key — just that he provide an unencrypted copy."
