To compel the production of a password, law enforcement needs to have a certain amount of information in hand before it can ask courts to hit uncooperative criminal suspects with contempt charges. > The Appeals Court decision raised an interesting point about device encryption. Without decryption, the alleged criminal evidence is nothing more than a scramble of bits and bytes of no use to anyone. With the correct password in place, the data is reintegrated into something usable -- which turns the production of a password into a testimonial act.
