Mirror A-Z text with the Atbash cipher while keeping numbers, spaces and punctuation in place.
This browser-side translator applies the Atbash mirror alphabet to pasted text. It is useful for puzzle checks, classroom examples and quick verification of simple substitution messages.
How it works
Atbash maps A to Z, B to Y, C to X and continues through the alphabet. The same operation encodes and decodes because the mapping is symmetrical.
Scope
The tool preserves spaces, punctuation and digits. It is a historical puzzle cipher, not protection for sensitive information.
