This Essay considers whether the government can force a person to decrypt his computer. The only courts to consider the issue limited their analyses to rote application of predigital doctrine and dicta. This is a mistake; courts should instead aim to maintain the ex ante equilibrium of privacy and government power. This approach—seeking equilibrium—was just endorsed by the Supreme Court in Riley v. California, a recent Fourth Amendment case. Yet Riley’s rationale also extends to the Fifth Amendment’s Self-Incrimination Clause, and maintaining equilibrium there requires permitting forced decryption. Because current doctrine can be interpreted as allowing forced decryption, courts should adopt that interpretation.
