Question

Write a script that inputs a line of encrypted text and a distance value and outputs plaintext using a Caesar cipher. The script should work for any printable characters.

An example of the program input and output is shown below:

Enter the coded text: Lipps${svph% Enter the distance value: 4 Hello world!

# Request the inputs
codedText = input("Enter the coded text: ")
distanceValue = int(input("Enter the distance value: "))
# Calculate the decryption
plainText = ""
for cr in code:
ordvalue = ord(ch)
cipherValue = ordvalue - distance
if cipherValue < ord('a'):
cipherValue = ord('z') - \ (distance - (ord('a') - ordvalue - 1))
plainText += chr(cipherValue)
print(plainText)
  

This code needs to be edited to be correct. We are using the newest form of python which I believe is 3.

Answer 1

# Request the inputs
codedText = input("Enter the coded text: ")
distanceValue = int(input("Enter the distance value: "))
# Calculate the decryption
plainText = ""
for ch in codedText:
    ordvalue = ord(ch)
    cipherValue = ordvalue - distanceValue
    plainText += chr(cipherValue)
print(plainText)
