I searched around but couldn't understand what this means: 'Many applications (and all Flask applications by default) will even used cookies with a MAC to store your session information so that you can pass state between independent workers without requiring a single database operation.' <-- what is MAC and how is it used?
The fifth amendment defense was overturned in the Boucher case because: "A District Court judge agreed with the government, holding that, given Boucher's initial cooperation in showing some of the content of his computer to border agents, producing the complete contents would not constitute self-incrimination." [1]. Without Boucher having given up the names and titles of his files, it is entirely reasonable to expect that the fifth amendment would hold when testimony is asked without knowing what is inside the encrypted space.
5th amendment is the right against self-incrimination. The response could provide self-incriminating evidence of an illegal act punishable by fines, penalties or forfeiture. Giving a password to your encrypted database could easily be interpreted as testifying against yourself as defined in the 5th amendment.
