This cipher is a basic encryptiontechnique that supports encoding and decoding operations on strings.• The encoding operation replaces each character in a string with another charactersome fixed number (shift) of positions down the ASCII table. The string can beencoded using any characters on the ASCII table and no need to use the circular list(where ‘Z’ is followed by ‘A’) image shown below. Your module must have a functionnamed encode() that takes a string and an integer shift (can be positive or negative)as parameters and returns the encoded string using the shift value. This module must Page 3 of 4also have a second function name decode() that takes an encoded string and aninteger shift as parameters and returns the decoded string. The decoding…

This function returns the message concealed in the input string that is the first letter of each word in the string (or char vector) and returns a string that contains the first letter of each word in the input string. >> string = ‘This is the first question of quiz’; >> m = encrypt(string) m = ‘Tittqofe’2. Caesar Cipher Create a function that takes two arguments (text, key) and returns a new encrypted text using the key. For example, if the input is "a" and the key is 1, it should move that letter 1 step in alphabetic order so the output would be "b". Examples: caesar_cipher("hello", 5) "mjqqt" caesar_cipher("hello world", 1)"ifmmp xpsme" caesar_cipher("a", 2)→ "c" Notes: The input is only letters and spaces; no special characters. What is Caesar cipher? Method in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. The method is named after Julius Caesar, who used it in his private correspondence.
