Tool usage guide
The Atbash Cipher tool allows you to instantly encode or decode text by applying the classic Atbash substitution method, which maps the first letter of the alphabet to the last, the second to the second-to-last, and so on.
Background
Designing a mystery game where players must find a hidden location.
Problem
Need to obscure the word 'SECRET' so players have to solve a cipher to find it.
How to use
Enter 'SECRET' into the input field and select 'Encode'.
Outcome
The tool outputs 'HVXIVG', which serves as the encrypted clue for the players.
Background
Found a note written in a simple substitution format during a research project.
Problem
The text 'Gsv jfrxp yrown' is unreadable and needs to be converted back to plain English.
How to use
Paste 'Gsv jfrxp yrown' into the input field and select 'Decode'.
Outcome
The tool reveals the original text: 'The quick brown'.
It is a monoalphabetic substitution cipher originally used to encode the Hebrew alphabet, where the first letter is swapped with the last, the second with the second-to-last, and so on.
No. The Atbash cipher is a simple substitution method and is not suitable for protecting sensitive or private information.
The Atbash cipher typically only affects letters of the alphabet; numbers and special characters usually remain unchanged.
Yes, the tool maintains the casing of your original input while applying the substitution.
You can attempt to, but the result will likely be nonsensical as the tool strictly follows the Atbash reversal logic.
