Suggest a cipher

There are many more codes and ciphers we could add. If you use one that is not here yet, tell us the name and, if you can, a link to a description of how it works. The most requested ones move to the front of the queue.

Report a mistake

If a chart or translation looks wrong, please include the exact input and what you expected. Precise reports get fixed fastest, and everyone benefits.
