This encryption method was physically unhackable: If anyone tried to force the container open, the information inside would self-destruct.ĭa Vinci rigged this by writing his message on a papyrus scroll, and rolling it around a delicate glass vial filled with vinegar. Once a message was "encrypted" inside the container only an individual with the correct password could open it. The dials have to be rotated to a proper sequence, spelling out the password, for the cylinder to slide apart.
