The Atbash Cipher (originally used to encrypt the Hebrew alphabet), simply reverses the plaintext alphabet to create the ciphertext alphabet. That is, the first letter of the alphabet is encrypted to the last letter of the alphabet, the second letter to the penultimate letter and so forth.

With this cipher, we simply take the alphabet and map it to its reverse. So when the Atbash cipher is used in English, A becomes Z, B becomes Y, and C becomes X.

Decode this name below written in Atbash Cipher. Use the space below to map the Atbash Cipher before answering the question.
