Hey John, i think the python script you were struggling with was because it wasn't casting to lower case, which i THINK is what the top commenter was saying.

Hi, is that a way to decypher vigenere without a knowing key?

Algorithm comment

I implemented a one myself but it didn't work. browsed the web and copy pasted multiple codes and they didn't work too! asked chatgpt for different implementations and it didn't work too.. what's wrong? I'm a beginner and I don't want to use ord()/chr() I prefer indices

It hurt my soul every time he pronounced Vigenere as "Veneer" or Kasiski as "Kasenky" lol
