Enigma M4 Breaker with GPU acceleration released on GitHub

The EnigmaM4Breaker repository is authored by Vladimir Cicovic and hosted on GitHub. It provides code that leverages GPU processing to attack the Enigma M4 cipher. The implementation targets the historical four‑rotor Enigma machine used by the German navy. GPU acceleration is intended to speed up key‑search operations compared with CPU‑only methods. The project includes build instructions and sample data for testing. Users can compile the code with standard CUDA toolchains. The repository serves researchers interested in cryptanalysis and historical cipher recreation. No warranty is offered, and the code is released under an open‑source license.
