- Feb 14, 2018 vigenere-cipher. A python code that performs a Vigenere cipher. Do both encryption of a plain text or decryption for a cipher text. In Vigenere cipher the key used in encryption or decryption is a single word and the message contains characters only.
- As far as OOP languages go, Python has a very weak sense of encapsulation. The only thing we do have are putting a single in front of a method or variable name, to signal that it is an internal variable/method and should not be used unless within the class itself and maybe derived classes.

I am trying to code in python using a caesar and a vigenere cipher so the user can pick which one they want to use and encrypt or decrypt. I have coded the caesar but really struggling with the vigenere can anyone please help as im lost with this.

I think there are limitations here with lower case and capital letters. You'd need to check for I wrote one that handles all default ASCII characters (95): For example: |

It's just the return text, that one by one figures out the proper character to return given the key. It's been a while since I wrote this snippet but if it can find a match of an ascii character, itll convert that, else it will leave it alone. |
