In many research works, there has been an orientation to studying anddeveloping many of the applications of public-key cryptography to secure thedata while transmitting in the systems, In this paper we present an approach toencrypt and decrypt the message text according to the ASCII(American StandardCode for Information Interchange) and RSA algorithm by converting the messagetext into binary representation and dividing this representation to bytes(8s of0s and 1s) and applying a bijective function between the group of those bytesand the group of characters of ASCII and then using this mechanism to becompatible with using RSA algorithm, finally, Java application was built toapply this approach directly.
