Encryption is the act of encoding messages so that others cannot understand it unless they know the decryption mechanism (the "key").
One of the earliest known uses of cryptology was employed by Julius Caesar [1]. He made messages secret by shifting each letter three letters forward in the alphabet(sending the last three letters of the alphabet to the first three). For instance, using this scheme the letter B is sent to E and the letter X is sent to A.
