Frequency Analysis using Quadgram Statistics and Python | The Code Book

Back again with #CipherSaturday Frequency Analysis part 2! In this video, I used quadgram statistics to apply frequency analysis on a given ciphertext and (sometimes) successfully decrypt it. As always, if you have any questions regarding anything in the video, feel free to contact me by any of the avenues below or just leave a comment.
