In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can read it. Encryption does not of itself prevent interception, but denies the message content to the interceptor. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, large computational resources and skill are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
The purpose of encryption is, to ensure that only somebody who is qualified to access data (e.g. a text message or a file) will be able to read it, using the decryption key.
Somebody who is not qualified to access the information can be excluded from doing that, because he does not have the required decryption key. Without it, it's impossible to read the encrypted information.
Encrypt is a television movie that premiered June 14, 2003 on the Sci-Fi Channel. Set in the year 2068, the Earth's surface is in a cataclysmic upheaval, much of it transformed into wasteland by unstoppable storms (the byproduct of the destruction of the ozone layer). It was directed by Oscar Luis Costo.
Plot
A few survivors have dedicated themselves to preserving and protecting what is left of mankind; among these is former Army Captain John Thomas Garth (Grant Show). Approached by Lapierre (Steve Bacic), a former comrade now employed by eco-profiteer Anton Reich (Art Hindle), Garth is made an offer he cannot refuse. In exchange for his father's and other's survival, Reich agrees to lead a small team of mercenaries into the impenetrable Vincent estate to "liberate" the priceless works of art that had been stored there. Accompanied by reconnaissance specialist Fernandez (Naomi Gaskin), sniper King (Matthew G. Taylor), and tech genius Ebershaw (Wayne Ward), Garth must find a way to circumvent Encrypt, the deadly computerized security system surrounding the estate. Other obstacles include the Rook, a killer robot, and Diana (Vivian Wu), the holographic security chief of the estate. With the help of Lapierre, Garth destroys the Rook and discovers that it actually protects a device that can restore the ozone layer. With the help of Diana, Garth triggers it, but presumably dies soon afterwards.
