The Mathematical expression of the encryption and decryption process of a Caesar cipher algorithm is expressed in equations 1 and 2 respectively. c=Ep, k                                                                                         (1) p=Dc,k                                                                                         (2) Draw the flowchart of a Ceasar Cipher cryptosystem. Write a Pseudocode to implement your flowchart in (a

Question 2: Encoding Cryptography is the study of trying to create secure information by obscuring the original message. One simple encryption method is to substitute letters from the original message with other letters. To make it harder to decrypt the hidden message, we may also remove clues such as the length of the words in the message and any punctuation or capitalization. Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: • Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included in the encrypted message at all. • The encrypted message will only contain uppercase letters. • Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet. In other words, A or a will become z, B or b will become Y, C or c will become x, .., z or z will become A. • The encrypted message will…

****NEEDS TO BE WRITTEN IN PYTHON****   Use the strategy of the decimal to binary conversion implemented in Project 4, and the bit shift left operation defined in Project 5 to code a new encryption algorithm. The algorithm should Add 1 to each character’s numeric ASCII value. Convert it to a bit string. Shift the bits of this string one place to the left. A single-space character in the encrypted string separates the resulting bit strings.

Python Programming

please code in python Implement an encryption function that tests that input 0xADE1 yields ciphertext (188, 153). You may hard-code these values for testing. Do NOT use ANY string/character manipulation or arithmetic functions to implement your solution.
