Caesar Cipher Disk

A simple Caesar cipher disk with different alphabets (latin, greek...).

This is a very simple Caesar cipher disk. You can turn both wheels individually (or not). You can lock screen orientation, keep screen on, turn on vibrations and play a sound. You can reverse the selected alphabet ("atbash style").

You can choose between :

* latin alphabet,

* hebrew alphabet,

* russian alphabet,

* greek alphabet,

* Eldar Futhark Runes (not supported on some versions of Android !),

* Union Cipher Disk used during the Civil War,

* Alberti Cipher Disk,

* Diana Cipher Disk (Diana Cryptosystem used during Vietnam War : http://www.blogbyben.com/2014/12/trigraphs-diana-pads-and-zombies.html - http://www.creativecrafthouse.com/index.php?main_page=product_info&cPath=143&products_id=1076),

* Vigenère Cipher Disk,

* Beaufort Cipher Disk,

* Custom Cipher Disk - limited to 60 characters per wheel. You can manage 10 custom disks.

You can create a printable version of the current disk, stored in a PDF file (inside the folder "CAESAR_CIPHER_DISK" of the application storage). A simple file viewer can be used to view a PDF file with your favorite PDF viewer or to delete (by a long click) the PDF files.

Note for the Union disk : a long click on the Reset button changes its default configuration.
