Vigenere Cipher Machine

This was my entry for the #WeeklyChallenge Secret Agent.
It can encrypt and decrypt messages, letter by letter.
It uses Vigenère Cipher algorithm with the key "STID". This method of cryptography depends hardly on the position of the character on the message, so if you miss type, you have to start the transcription all over again.

Controls:
- Top seat camera
- 9 to swap between encrypt (arrow pointing right) and decrypt (arrow pointing left) modes. It doesn't matter which mode the machine is on, your input will always be on the left display, and so the output'll be in the right one.
- 0 to reset the machine. It works if it bugs (top red lights behaviour will let you know when errors have ocurred). Remember to reset the machine everytime you're working with a new message, or if you misstype a character.
- All characters work as inputs for the machine, with the exception of B, C, F and R, due to them being reserved words for the game. They are substituted for B = 1, C = 2, F = 3, R = 4.
- Leftcontrol to clean up, dont let any evidence for your enemies ;)

Example: Decrypted message => Trailmakers is awesome
Encrypted message => LKILDFINWKA LK TEHKHUH
