The Vic cipher was a pencil and paper cipher used by the Soviet spy Reino Häyhänen, codenamed "VICTOR". It has several important integrated components, including mod 10 chain addition, a straddling checkerboard, and a disrupted double transposition. The alphabet it uses consists of 28 characters over 3 rows and 10 columns marked with numerical coordinates. By default, the 28 characters are the standard letters A - Z along with the characters "." and "/". You can customize this below with a keyword or arrange it in a custom order of your choosing. See Wikipedia for more information.
Enter a keyword, phrase or alphabet and the rest will be calculated for you.
Optional: Enter a set of numbers that would be used to over-encrypt/decrypt the code.
