Abstract
Information is one of the single most important factor for understanding a situation as well as deciding upon a solution by effectively devising a working method. Thus the magnitude of securely delivering information to the correct individual or organization has always been a prime concern. The field of Cryptography deals with such necessities as to encrypt the information in such a way so that only the intended receiver, equipped with the right armoury, can decipher the message. Here in this paper a method for encrypting character data has been presented whereby the ASCII values of individual character is converted into their Hex values before they are turned into their binary form, and randomly assigned a single digit Odd integer value for a 1 and single digit Even integer value for a 0. Going forward we do some more processing of the data to make it even more secure, these will be discussed in due course. The receiver must possess a valid Image key in order to decrypt the text. This image is generated during encryption from two RGB (Red, Green and Blue) values- having a difference of a random number produced within the range of total length of the plaintext.
