It is suggested that Caesar might have encrypted his correspondence replacing each letter in the plain text by a letter some fixed number of positions down the alphabet. However, this method is not very safe. When trying to decrypt such a message you can look for the most frequent letter in the text which is more often than not allocated to the letter “e”. Have a try! Encoding: - Click on “Text input” - Enter your plain text and click the return key - Choose the shift (click on the blue arrows or on the arrow keys) - Click on “Encode” Decoding: - Click on “Text input” - Enter the encoded text and click the return key - Choose yourself the shift ( click on the blue arrows or on the arrow keys) or click on Caesar to let him do it for you! After having analyzed the frequency of the letters in the text, he will let you know the most promising alphabet shift. - Click on “Decode” - If it doesn't work the first time, click on “Caesar” again for a further recommendation.
