The Vigenère Autokey Cipher is a more secure variant of the ordinary Vigenère cipher. It encrypt the first letters in the same way as an ordinary Vigenère cipher, but after all letters in the key have been used it doesn't repeat the sequence. Instead it begins using letters from the plaintext as key.

Hi @jmeline, I would like to take in charge this task!

Could you prepare/suggest a test class to help check out the implementation works correctly?

Thank you

@jmeline this has been resolved in #41, I think we can close this
