A CryptoQuote is a simple substitution code where each letter that appears may stand for a different letter. The substitutions are consistent throughout the puzzle. Punctuation is not translated.
For example: AMXBMAAYQ = ENGINEERS
"In'hn qnno mjbom gqjtl lcby guu ixjom. Lcby Wbylnx Ylgz-Vtel by jfgz. Cn'y g ygbujx, cn'y bo Oni Zjxf. In mnl lcby mtz ugba, in ijo'l cghn goz lxjtqun!"
