This is my second encoder, after a while. This one works on the Vigenere Code or Cipher. Basically, type in a password in the blue letters. Then, click the '...... Mode' Button to change it to Encode or Decode Mode. Then, click Ready to start. Then you can just type what you want to code, and the code will be shown on the screen. The left button is backspace. You can also click 'Stop.' Have fun coding! ~Abrulz
