High Quality Content by WIKIPEDIA articles! Dvorak encoding is a type of encoding based on the differences in layout of a QWERTY keyboard and a Dvorak keyboard. There are two main variations: One is achieved by typing in the Dvorak layout on a QWERTY keyboard, and the other is similarly achieved by typing in the QWERTY layout on a Dvorak keyboard. This effectively makes Dvorak encoding into a monoalphabetic substitution cipher like ROT13 and the Caesar Cipher, since each one character translates to one other character in a consistent pattern.
