WebEven if an adversary doesn't know a piece of ciphertext has been enciphered with the Atbash cipher, they can still break it by assuming it is a substitution cipher and determining the key using hill-climbing. The Atbash cipher is also an Affine cipher with a=25 and b = 25, so breaking it as an affine cipher also works.
