With a warrant from a judge people should be compelled to provide access to their encrypted files or be in contempt of court with all that entails. Anything else is overreach.
Wonderful idea. All I need to is to create an encrypted file with pedo pictures or terrorist plans or just white noise, send a copy to all my enemies, and tip off the authorities.
Yea that's extra fun if someone else sent it then. Government puts them in jail for not having the encryption key for something someone else encrypted.
