![]() ![]() This function creates an array of rotor positions to use in enigma encryption/decryption. The only difference with getRotorArr is that this function uses the inverse of the reflector. This function creates an array of rotor objects in the order they need to be performed for enigma decryption. The returned value is an array of rotor objects in the order they need to be performed. plugboard - A rotor object that is the plugboard to be used.reflector - A rotor object that is the reflector to be used.rotors - The array of rotors to be used.This function creates an array of rotor objects in the order they need to be performed for enigma encryption. The returned value is the incremented array. pos - An array of integers that is the rotor position array to be incremented.This function increments a rotor positions array. This function creates an identity rotor object (it creates a rotor that does not change any letter). The returned value is a rotor object that is the plugboard created. in_str - This string contains space separated pairs of letters to be swapped by the plugboard being created.This function takes a string containing pairs of characters to be swapped by a plugboard and create a plugboard from this. The returned value is an array of integers representing the permutation. in_str - The string representing the permutation to be created.It then constructs an array of the relative ordinal values of each letter before and after the permutation. It does this by checking that the lowercase string is 26 characters long and contains letter. This function turns a string representing the result of a permutation on the alphabet into that permutation for use in constructing rotors. _str_ - This method returns a string that is the alphabet 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' under the permutation of this rotor in position 0.inverse - This method creates a rotor object that is the inverse of this one.With the parameters letters are given as integers with 'A' as 0, 'B' as 1, 'C' as 2, etc. permute - This method performs the permutation of the rotor on a given character (given as an integer) with the given rotor position which is also given as an integer.It instantiates an object of the class and stores permutation as an attribute. _init_ - This method takes a single parameter permutation (an array integers that stores the relative changes of different characters under the permutation).This class is to implement the rotors and permutations (plugboard and reflector) used by Enigma. To implement Enigma within python, we have put together a tutorial to talk you though how to code an Enigma function: ![]()
