The US Constitution has a right against self-incrimination to put a stop to forced confessions (like through torture). But revealing a password cannot possibly be a confession, because all it can do is reveal further evidence. I suspect at some point US courts will rule that being compelled to hand over a password is not 'self incrimination' for the same reason that being compelled to let police search your property isn't. The abuses that rule was put in place to stop just wouldn't apply so interpreted the constitution in that way doesn't make much sense. (and the UK has no equivalent rule against self incrimination ... not sure any country does actually)
