hello-world

Basic "Hello, World!" Sample

In this example we encode Hello, World! string using enigma machine.

before encoding process, we have to generate rotor data and feed them to the enigma machine.

We prepare another simple program called rotor_data.c that compiles from Makefile and generates three randomly rotors for each individual langauge sequences.

rotor_data.c

Is responsible to generate rotors data.

This program uses enigma_rotor_random libenigma api to generate random rotor data using en.h language pack which is used for English.

for each individual sequence located there, it generates three rotors (By default, Configurable through Makefile). for English language pack there are three sequences. so:

• Alphabet (3 Rotors)
• Digits (3 Rotors)
• Punctuations (3 Rotors)

Then "serializes" rotors data to ./rotors.dat file (By default, Configurable through Makefile) and Done!

main.c

The logic of example is located in here.

This program first deserializes rotors data from ./rotors.dat file and then instantiate a enigma engine and feeds the language and rotors stuff to engine and encodes Hello, World! string.

The output of this program is just encoded form of Hello, World! string with ./rotors.dat rotors data.

Building

Before building the examples, you have to make sure that you already builded the libenigma or installed.

If you didn't, go to project root directory and run:

$ make build-lib

After building come back here and run:

$ make
$ make run # Runs ./rotors_data && ./main
