Question: - - - You are given two affine ciphers for which encryption is described by this pair of formulae: y = 5 x + 1

---You are given two affine ciphers for which encryption is described by this pair of formulae: y=5x+12
(mod26)y=11x+23(mod26)
Write down the equivalent single encryption formula when encrypting with the first formula and then
the second formula. It will be in the form y=x+(mod26) where 025.
1) You encrypt messages using the affine function 9x+2mod26. Decrypt the ciphertext GM.
2) You try to encrypt messages using the affine cipher 4x+1mod26. Find two letters that
encrypt to the same ciphertext letter.
