The first letter is replaced with the last letter, the second with the second-last, and so on. The Atbash Cipher simply reverses the plaintext alphabet to create the ciphertext alphabet. The simplest example of this is the Atbash or reverse-alphabet cipher. The Atbash cipher was originally made to work with the Hebrew alphabet, but can be modified to work with any alphabet with a limited amount of characters. A keyword is used as the key, and it determines the letter matchings of the cipher alphabet to the plain alphabet. Episode 20 is trickier as it uses a combined cipher, requiring you first to use the A1Z26 cipher, then the Atbash cipher, and finally the Caesar cipher … – user4581301 Apr 24 '19 at 17:20. endstream endobj 15 0 obj <> endobj 16 0 obj <> endobj 17 0 obj <>stream Atbash is an ancient type of cryptography that was originally used to encode the Hebrew language by transposing certain letters. To use Atbash, you simply reverse the alphabet, so A encodes to Z, B to Y and so on. It is the simplest cipher because it only allows one possible way to decode a word. Like A = Z, B = Y, C = X? This is why we wanted to give exercism users the option of making their solutions public. For example, using the English alphabet (ABCDEFGHIJKLMNOPQRSTUVWXYZ) and its reverse (ZYXWVUTSRQPONMLKJIHGFEDCBA), let’s encrypt the message “Attack at noon”.

New coders may receive an assignment that involves creating an atbash cipher writing program. I use your code but create a dictionary where each name has a value that is equal to what Atbash would convert it to. Because reversing the alphabet twice will get you actual alphabet, you can encipher and decipher a message using the exact same algorithm. Here is the English version of the atbash cipher, using the same right-to-left ordering (since the code transposition does not depend on how the cipher is displayed here). The result will appear below. The Atbash cipher is also an Affine cipher with a=25 and b = 25, so breaking it as an affine cipher also works. A becomes Z, B becomes Y, C becomes X, and so on.
