Enigma
Description
The Enigma machines were a series of electro-mechanical rotor cipher machines developed and used in the early- to mid-20th century to protect commercial, diplomatic and military communication. Enigma was invented by the German engineer Arthur Scherbius at the end of World War I.
This is a simple Enigma emulator which supports plugboard and rotor files and has a default reflector plugged in. Other components are easily pluggable by defining a new machine model(see Machine.hpp and Enigma.hpp) and new components(see Component.hpp).
Runnning
To run the testsuite:
make test
To run the program:
make
./enigma <plugboard_files> <rotor_files>
The input supported is upper case chars and spaces. To stop the input stream press CTRL + D. The message that you see will be the encoded message.
Configuration files
The configuration files are of 2 types:
- plugboard - the plugboard is made out of consecutive pairs of numbers that describe the plugboard connections
- rotor - the rotor describes the shift for each character
There are sample rotor configuration files in rotors/ and plugboard configuration files in plugboards/.
