Please write functions to decrypt both the shift (Caesar) and linear ciphers. Also, answer the questions in Python and show how it typed and ran inside the client. The def is what to start with 1) Write a function called decrypt that accepts three numbers (c, m, and k) and returns the corresponding plaintext (p) value as a number. You can assume the modulus (n) is 256. You will need to compute the multiplicative inverse of m mod 256 to...
