1. Decrypt these messages that were encrypted using the Caesar cipher.
a) EOXH MHDQV (BlueJeans)
b) WHVW WRGDB (TEST TODAY)
c) HDW GLP VXP (EAT DIM SUM)!

2. Suppose that the ciphertext DVE CFMV KF NFEUVI,
REU KYRK ZJ KYV JVVU FW JTZVETV was produced by encrypting a plaintext message using a shift
cipher. What is the original plaintext?

3. Encrypt the message GRIZZLY BEARS using blocks
of five letters and the transposition cipher based on the
permutation of {1, 2, 3, 4, 5} with σ(1) = 3, σ(2) = 5,
σ(3) = 1, σ(4) = 2, and σ(5) = 4. For this exercise, use
the letter X as many times as necessary to fill out the final
block of fewer than five letters.

4. Decrypt the message EABW EFRO ATMR ASIN which
is the ciphertext produced by encrypting a plaintext message
using the transposition cipher with blocks of four
