The operation of a cipher code usually depends on a piece of auxiliary information, called a key, or a cryptovariable. The encrypting procedure is varied depending on the key, which changes the detailed operation of the encoding algorithm. A key must be selected before using a cipher to encrypt a message. Without the same key, it should be difficult, if not impossible, to decrypt the resulting coded message into the original message.
This nano program would seem to use complex quantum technology to determine the cryptovariable for any known encoding process.
