Complete the caesarCipher function in the editor below.caesarCipher has the following parameter(s):string s: cleartextint k: the alphabet rotation factorReturnsstring: the encrypted stringInput FormatThe first line contains the integer, , the length of the unencrypted string.The second line contains the unencrypted string, .The third line contains , the number of letters to rotate the alphabet by.

Write a Python program to strip a set of characters from a string. Encrypt a given message by “rotating” each letter by a fixed number of places. To rotate a letter means to shift it through the alphabet, wrapping around to the beginning if necessary, so ‘A’ rotated by 3 is ‘D’ and ‘Z’ rotated by 1 is ‘A’. Write a python function called rotate_word() that takes a string and an integer as parameters (to rotate), and returns a new string that contains the letters from the original string rotated by the given number. For example, "cheer" rotated by 7 is "jolly" and "melon" rotated by -10 is "cubed"

What is the ciphertext of "software" using a Caesar cipher?

Single File Programming QuestionProblem StatementGeorge, a secret agent, needs a program to encrypt a character using a shifting method. The program should prompt him to enter an alphabet and a shift amount as register storage class inputs. The encrypted character is obtained by shifting the input alphabet by the specified amount in a circular manner. Uppercase and lowercase letters wrap around, ensuring a seamless shift within the alphabet.Example: If the character 'y' wants to be rotated 6 times, it wraps around the alphabet after reaching 'z'. The shifting process results in the output 'e'.Input format :The input consists of a character c representing the alphabet on which shifting happens and an integer n representing the number of times it has to be shifted, separated by a space.Output format :The output prints the character after shifting the input alphabet (to its right) n times.If c is not an alphabet, the output prints the input character as such without shifting.Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:c should be a valid ASCII character.1 ≤ n ≤ 20Sample test cases :Input 1 :A 1Output 1 :BInput 2 :Z 2Output 2 :BInput 3 :c 4Output 3 :gInput 4 :y 6Output 4 :eInput 5 :# 5Output 5 :#Input 6 :b 20Output 6 :vNote :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.Marks : 10Negative Marks : 0

Alice and Bob want to communicate securely over an insecure channel where Evecould be listening. To ensure their message remains confidential, they decide to usea simple substitution cipher for encryption and decryption, where each letter in thealphabet is shifted by a fixed number of places.For this exercise, use a shift of 3 places to the right (a Caesar Cipher). For example,'A' becomes 'D', 'B' becomes 'E', 'Z' becomes 'C', and so on. Spaces and punctuationare not encoded; they remain unchanged.Alice wants to send the following message to Bob: "HELLO WORLD".a. Encrypt Alice's message using the specified shift. Provide the encrypted text.………………………………………………………………………………………………[1]b. Discuss the security of using the Caesar Cipher for encrypting messages.Consider scenarios where Eve knows or does not know the method ofencryption.……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………[1]

Make a function that encrypts a given input with these steps:Input: "apple"Step 1: Reverse the input: "elppa"Step 2: Replace all vowels using the following chart:a => 0e => 1i => 2o => 2u => 3# "1lpp0"Step 3: Add "vit" to the end of the word: "1lpp0vit"Output: "1lpp0vit"NotesAll inputs are strings, no uppercases and all output must be strings.i/p:bananao/p:0n0n0bvit
