Cipher devices or machines have commonly been used to encipher and decipher messages. The first cipher device appears to have been employed by the ancient Greeks around 400 BC for secret communications between military commanders. ... Advances in radio communications and electromechanical technology in the 1920s brought about a revolution in cryptodevices -- the development of the rotor cipher machine. ... Since the early 1970s, cryptologists have adapted major developments in microcircuitry and computer technology to create new, highly sophisticated forms of cryptodevices and cryptosystems ....  1, record 3, English, - cipher%20device

According to Bengt Beckman the worlds first cryptomachine was swedish... The machine, called in 18th century swedish: "Chiffre-Machinen", consisted of 57 wheels mounted on a common shaft. These wheels were housed in an oblong cylinder. On half of the circumference of each wheel, the normal ordered alphabet was engraved, and on the other half numbers between 0 and 99 were likewise engraved, but in mixed order, with each of the 57 wheels having their own mixed sequence. On one side, along the length of the cylinder, was a slot wide enough to allow one letterposition of all the 57 wheels to be seen, and on the opposite side a similar slot allowed a row of 57 figures to show themselves.  2, record 5, English, - ciphering%20machine
