How much more efficient is one?
- Encrypt the messageWATCH YOUR STEPby translating the letters into numbers, applying the encryption function f(p) = (−7p+2), and then translatingthe numbers back into lettersTasks: Part A: Develop a UDP/IP server program in java that waits for clients to server. The server responds to the client with one of the following based on client’s request: Export secret key generated using KeyGenerator Export Text and Message Digest Export Text and Digital Signature Send original text for the encrypted text received from client Part B: Develop a UDP/IP client program that make request secret key, Message Digest, Digital Signature and original text by sending the encrypted text to server program developed (in Part A). This program will display the various objects received from server on its console.DES 1. You are a junior IT executive at your department dealing with the DES encryption key. From the random key generator, you are given the secret key (E0E0E0E0F1F1F1F1)hex to encrypt a message. a)What is the output of the key after it is applied with the parity bit drop process box in Figure 1?
