What Is This?

This is an Enigma simulator. In C. So you can throw it into Ghidra and run PCode Emulation on it.

Building

Have GCC. Run make. Defaults to thinking you're on x86 64 bit, but just runs GCC.

If you want to build for a different architecture, make ARCH=aarch64 for instance. Supported architectures are aarch64, x86, armel, and powerpc. The default tools that get used are from Debian's "crossbuild-essential" series, so on Deb/Ubuntu install those with apt install crossbuild-essential-ARCHITECTURE.

Usage

Usage: ./enigma.x64 key rotor\_order swaps enc/dec\_text

	key          - 3 characters, the initial settings on the rotors
	rotor_order  - 3 digits, the rotors to use.  1, 2, 3,
	               and 5 implemented.
	swaps        - An even number of characters, where each
	               pair is swapped on the plugboard.
	enc/dec_text - The text to encode or decode.
