Yes, and you can break Bob and Cindy's fingers to get their passphrases. That is a very easy step. That is why steganography should be used.  There shouldn't even be an ecrypted text for them to try to decrypt, at least as far as they know. Because once, there is, they can always get the password. The next best thing is is fake encryption or some kind of nested encryption, so that the outer layer decrypts to something plausable but ultimately benign.<p>A password doesn't even fall under 'free speech', so even in a free country like US one can get slapped with 'obstruction of justice' if one doesn't provide a password.   I'll leave it to your imagination to what happens in other, more oppressive countries...
