Attributes¶
- enigma.enigma.ROTOR_LEN¶
- class enigma.enigma.Enigma¶
An Enigma machine.
- press_key(self, letter_input)¶
Press a key on the machine.
- Parameters
letter_input (str) – the key pressed
- Returns
the letter bulb that lights up
- Return type
str
- step_rotors(self)¶
Step rotors forward.
Step first rotor, turning over rotors 2 and 3 if required.
- class enigma.enigma.Rotor(wiring, turnover_notch_letter)¶
A single rotor for scrambling an input pin to a different output.
- wire_up(self, output_letter_order)¶
Wire up the rotor.
Create a dict to implement the input/output wiring of the rotor pins. For example: “0”: “7”, “1”: “17”, “2”: “2” :param output_letter_order: order of the 26 output pins :type output_letter_order: str
- step(self)¶
Advance the rotor by one.
- trace(self, input_pin_pos0)¶
Trace an input pin through the rotor to an output pin.
- Parameters
input_pin_pos0 (int) – input pin from the previous component (machine or previous rotor) relative to position 0 of the rotor
- Returns
output pin relative to position 0 of rotor
- Return type
int
