To exchange secret messages between two users, while using the processes of encryption and decryption on the message with the help of a secret key. We will see briefly how the key is being generated. Key will be generated by the process of Diffie-Hellman key exchange algorithm, which does not follow the rules of sharing secret key instead two parties will develop the secret key together while exchanging partial information for key generation. After the generation of secret key, we will use DES (data encryption standard) algorithm for sending the message, while using the public media, i.e., Internet as communication channel and in receiver’s side show that message is well received without any third party alteration and can be decrypted perfectly into originally sent plain text.
