GS CrypNTo Club: Probability Everywhere 2 | Vigenère cipher, Kasiski Examination and Alan Turing

This is the second probability everywhere meeting. In this meeting, we reviewed what we have talked about in our previous probability everywhere meeting, we introduced Kasiski examination and Turing's work on incorporating this Vigenère cipher with cryptanalysis and probability theory, and finally we looked at the weaknesses of this examination.
