The ultimate app for cryptographers!

Gordian lets you make your own secret codes by using a combination of different codes and ciphers. You can use these codes to send secret emails and text messages to your friends, or to keep your own information safe from prying eyes.

Gordian currently lets you mix and match the following codes:
+ Atbash Cipher
+ Base64*
+ Binary*
+ Caesar Cipher
+ Hexadecimal*
+ Keyword Cipher
+ Morse Code*
+ Reverse Code
+ Transposition*
+ Vigenere Cipher*

* Pro version only.

By combining multiple codes together, you can create extremely strong codes that are very difficult for even the experts to crack!
