Vigenere Cipher With Arduino

Few years ago, Digital Fortress by Dan Brown caught my attention and one particular thing stuck on my mind. Kryptos, the sculpture by Jim Sanborn which consists of ciphered text of which the first two parts are encrypted by Vigenre cipher. I started tapping into cryptography and found out how much fun it is (Dan Brown’s fans will sure understand). This program allows you to encrypt/decrypt text using a keyword.”
