WebApr 11, 2024 · I am trying to solve a substitution cipher with dictionary keys and a rotation shift. For example: keys: 'A':'Z', 'B':'Y', 'C':'X' and so on..... plaintext = AAABBB. cipher text with 0 rotation = ZZZYYY. cipher text with 1 rotation = ZYXVUT. Identical letters are encoded differently because encoder increments the letter by rotation every time ... Web# cipher is an array which we append each encrypted letter inside it: cipher = [] # first we convert matrix(our chipher key) a python array to numpy array : matrix = np.array(matrix) # get the matrix corresponding to our words: result = generate_matrix_word(words) # we multiply our two matrixes (our matrix of words and cipher key) # then we get ...
