During an investigation where one is a suspect or one may have information about a suspect be required to relinquish passwords or keys to personal encrypted data to the authorities? For example maybe someone has in an encrypted container on their personal computer with data used or pertaining to a crime, stolen media, stolen government documents, or data that can be used to solve a crime. The authorities have evidence that is beyond reasonable doubt that the encrypted data contains such files pertaining to the crime. This container may contain other sensitive data that does not pertain to any crime such as ss numbers if that makes a difference. Does that person legally need to relinquish password or keys if asked by authorities?
This question makes me think how secure is an encrypted file in a world run by people? Can the police come in my door, steal my computer and hold me in jail until i give my passwords up?
This question can also pertain to a company and consumer relationship where the company may hold encryption keys to consumers data.
