  • dmamakas2000/cryptanalysis-python

    In this project, we experiment with the use of diverse cryptographic algorithms. First, we attempt to encrypt a plaintext message using the Vigenère Algorithm and a fixed-length encryption key. Afterward, we experiment with the decryption of the produced cipher using Kasiski's Method, as well as the Index of Coincidence statistical test.
