Question: PYTHON The transposition cipher can be generalized to any number of rails. Write a function to implement a three-rail fence cipher that takes every third

PYTHON

  1. The transposition cipher can be generalized to any number of rails. Write a function to implement a three-rail fence cipher that takes every third character and puts it on one of the three rails. Test your algorithm with two sample input as shown below.

2. Write the substitutionDecrypt method. Test your algorithm as shown below. Your code should work for any key.

Sample output using testKey1 (zyxwvutsrqponmlkjihgfedcba) and cipherText message ('gsv jfrxp yildm ulc') from substitution.py file
