- Create a program for caesar cipher in which the user enters a string of lowercase alphabets and the shift. The program should display the encoded string in the output. You can use the programming language of your choice but add the output screenshot in the file and test your code for the test case "fzyxtnavhal".Program Specifications: Your task is to write a program that can decrypt a message that has been encoded using a Caesarcipher. Stated another way, you need to find the “shift” for the cipher. Once you have the shift,you know the mapping so you can decrypt the message. the encryption code. use python. def encrypt(text, r): #abcdefghijklmnopqrstuvwxyzresult = ''for i in range(len(text)): # Hello Khoorchar = text[i]if char.isupper():result = result + chr((ord(char) + r - 65 ) % 26 + 65)else:result = result + chr((ord(char) + r - 97) % 26 + 97)return result while True:msg = input("\n\tEnter a String / message e.g. Today is Thursday ")rotation = int(input("\n\tEnter number of rotation e.g. 3 "))print("\n\tOriginal Message is==> ",msg," with rotation ",rotation, " The CypherText ", encrypt(msg,rotation)) No hand written and fast answer with explanationGoal:Experimenting with AES-128 symmetric key cipher. Note:Using Python programming language that provided libraries for AES. Description:PART 1: write a program that uses AES-128 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and the outcome of the decryption, respectively.- To test this program, here's an example of an encrypted message (ciphertext.dat) and its 128-bit secret key (key.dat). PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have the first 96-bits of the 128-bit secret key (last 4 bytes of the secret key are missing!) The program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respectively. The program should print out on standard output the missing 4 bytes of the key in…
- Using matplotlib, a Python program that reads the contents of the file see attached then plots the data as either a line graph or a bar chart. Be sure to display meaningful labels along the X and Y axes, as well as the tick marks. The file contains the average gas price for each week in the year 1994. (There are 52 lines in the file.)

If the strings are not sorted in the file, display the first two strings that are out of order.Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5.

- IN PYTHON: Decrypting with ascii I have a file called 'dict.txt'. This file contains over 50,000 english words. One word from this file is used as a key (we do not know which one of course). Some have capital letters. I have another file called 'decrypt.txt' which is a file containing a string of numbers i must decrypt using a key found in the 'dict.txt'. This 'decrypt.txt' file message has length of 300. My question is, since i do not know which word (from the file with the 50,000+ words) is the key I must use to decrypt the other file, how do I write a function that: loops through all possible keys from 'dict.txt' to find the one that decrypts my file 'decrypt.txt' best? Somehow i must count how many 'words' are actual words to determine which key is best and then print my final decrypted message.Write a python code that reads a file (contents of the file pasted below) and shows the average of all values shown in the last column.
