It simply substitutes letters by shifting by a fixed number that you specify between 1 & 25.To send a secret message start by typing or pasting a message into the "Input" field. Then enter a digit between 1 & 25 in the "Key" field and hit "Encrypt." The encrypted message will appear in the "Output" field. From there you can send the encrypted message via Email, iMessage/Text, Twitter, or Facebook status! The key can be sent with the message in a simple format, C15. The "C" stands for Caesar, and the 15 is the shift key of 15. You also have to option of not sending the key with the message for more security.When you receive an encrypted message, copy and paste it into the top "Input" field, enter the key between 1 & 25, press the "Decrypt" button and your secret message will be decrypted for you to read!Somebody who doesn't know the secret number of shifts can decipher this message, but it's very time consuming.Note 1: Only letters from "A" to "Z" are supported.Note 2: This is an text encryption app, but this app should not be used to cipher any company or government secrets.Note 3: iOS 5+ only (sorry iOS 4)
