Atbash Cipher

Encode and decode the Atbash cipher, which mirrors the alphabet so A becomes Z, B becomes Y, and so on. Atbash is symmetric, so the same action encodes and decodes. Letters keep their case and other characters are preserved.

Built for atbash cipher workflows and closely related tasks like atbash decoder.

How it works

  • Type or paste the text you want to convert.
  • Each letter is mapped to its mirror position: A↔Z, B↔Y, C↔X, and so on.
  • Run the tool again on the output to decode it back to the original.

FAQ

What is the Atbash cipher?

Atbash is a substitution cipher that reverses the alphabet, mapping A to Z, B to Y, C to X, and so on. It is one of the oldest known ciphers.

How do I decode Atbash?

Run the encoded text through the tool again. Atbash is symmetric, so encoding and decoding are the same operation.

How is Atbash different from a Caesar cipher?

A Caesar cipher shifts letters by a fixed amount, while Atbash mirrors the alphabet. Atbash has no shift value to choose.
