The best way of exchanging the information is communication, due to this security of communication system become more challenging and typical day by day.Cryptography plays a major role in giving the data security which is transmitted over the internet work.The process of transforming the plain text is called encryption.Plain text is supposed to be the input of every encryption process and the corresponding cipher text is the output, whereas in the process of decryption the situation is opposite.As the process of decryption is converting cipher text in to plane text.This study presents the algorithms based on ASCII values of characteristics in the plane text for the encryption and decryption process.Since this effort has already been done by many researchers, but here we are trying to enhance the security by modifying the previously used string keys for the data encryption and decryption.The algorithm is presented for the symmetric cryptosystem in which same key will be used for the encryption and corresponding decryption process.
