Using Python, how would I alter the functions for atbash_encrypt() and atbash_decrypt(crypto) so that they'll be able to work with ab.atbash_encrypt('HELLO') and ab.atbash_decrypt('SVOOL')?

Please help me solve this with python. Add your code. In order to have have the decimals correct, make sure you are running the following command in numpy:np.set_printoptions(precision=7, suppress=True, linewidth=100) The expected output is: 1.5549999999999995

Answer these questions with Python expressions. 'Supercalifragilisticexpialidocious' has how many letters? Is 'ice' a substring of 'Supercalifragilisticexpialidocious'? Supercalifragilisticexpialidocious, Honorificabilitudinitatibus, or Bababadalgharaghtakamminarronnkonn—which is longest? Which composer is first in the dictionary: Berlioz, Borodin, Brian, Bartok, Bellini, Buxtehude, or Bernstein. Last one?

Please visit https://en.wikipedia.org/wiki/Caesar_cipher. You will be writing code that encrpyts and decrypts using this method. Specifically, you'll be writing functions: E,(1) (z+ n) mod 27 D„(1) (1- n) mod 27 On the Wiki page, the modulus (%) is 26, but we're using 27-why? We are adding an extra symbol { for space. Please visit https://en.wikipedia.org/wiki/ASCII. If you look at the printable ASCII characters, you'll notice that { (hex value 7A) follows z. Thus we can easily extend our cypher to include this symbol for space. Let's see how. 1 sentence "this is a secret message about the class" sentence sentence. replace (" ", "{") 3 print (_sentence) 4 es - 5 for i in sentence: es - encrypt (i, 5) 7 print (es) 6 8. 9 ds - 10 for i in es : 11 ds - decrypt(i, 5) 12 13 O_sentence ds. replace ("{", " ") 14 print (o_sentence) has output 1 this {is{a{secret{message{about {the{class 2 ymnxenxefexjhwjyerjxxfljefgtzyeymjchqfxx this is a secret message about the class In this cypher we are...

A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right. For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation. Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input. • The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position. • The script shiftRight performs the inverse operation. • Each script prints the resulting string. An example of shiftLeft.py input and output is shown below: Enter a string of bits: Hello world! ello world!H An example of shiftRight,py input and output is shown below: Enter a string of bits: Hello world! !Hello world

Write a python program to validate whether a JSON is valid or not. Don't take response from server since it is always correct Make 2 JSON's, 1 --> Correct & 2 ---> In Correct

Let's say that an AES-128 key was 00 00 00 01 00 00 00 02 00 00 00 03 00 00 00 04. (It's a bad key because it's not random, but we'll use it in this problem anyway.) This is used as "round key 0" what are the first four bytes in "round key 1"? Write each using exactly two hex digits (using lower-case hex for a-f).

This question does not require you to run any R code. But suppose you did run the command sd(rpois(n, lambda)) where λ=(1+1)/2 and n was set to be an extremely large number. What answer would you expect? Give your answer as a decimal to two decimal places.

USING KEIL PLEASE.. Ciphers use many bitwise operations for cryptography. Write an ARM assembly program to use ciphers. See the steps below to implement the cipher. In this program, you will implement a "Symmetric Encryption". Create three variables, Plaintext, Key, and Cipher (5 Points) For encryption, design a key value, assign the last nonzero number of your student ID (#900 number) in a variable called "Key" (5 Points) For example: if your 900 number is 90012450. Assign 5 to the variable Key and use it as the Key for encryption. Use this link for the Links to an external site.video to understand Symmetric Key Cryptography and implement that for encryption and decryption. For the variable Plaintext, assign any four-letter word. Encrypt the plaintext using the value in Key and store the encrypted text in the variable Cipher. Test the encryption by decrypting and storing the decrypted text into register R5. Provide comments to each statement
