The Eleventh Circuit of the US Court of Appeals recently handed down a landmark ruling, establishing a precedent under which the contents of an encrypted hard-drive are protected by the Fifth Amendment s ban on self-incrimination. John Doe is suspected of possession child pornography. The judge compelled Doe to reveal the encryption passes to his hard-drives. When Doe refused, pleading the Fifth, the court held him in civil contempt, and incarcerated him. The court agreed with the EFF, ruling that the act of decrypting data is testimorial.
