## Project history and usage

MFCUK, the MiFare Classic Universal toolKit, is an nfc-tools project for MIFARE Classic security research. Its README identifies the main tool as a Mifare Classic DarkSide key recovery tool, previously known as zv_mf_dark_side, and lists a bibliography of MIFARE Classic cryptanalysis work from the late 2000s. The AUTHORS file names Andrei Costin as author, with Romuald Conty contributing libnfc ports and the Nethemba Core Team contributing core autoconf/automake/configure and packaging work.

### Project history

The project occupies a narrow but recognizable place in the NFC research toolchain: it combines libnfc-compatible readers, crapto1-related cryptanalytic code, and MIFARE Classic attack demonstrations in a command-line package. The README credits researchers, Proxmark/libnfc contributors, and the Nethemba team, and it explicitly points to MFOC as the earlier open-source GPL nested-authentication key recovery implementation.

### How it is used

In practice, MFCUK is used by security researchers and NFC auditors working with owned or authorized MIFARE Classic tags. It is packaged in Homebrew, Debian/Ubuntu, and Nix as a specialist CLI rather than a general NFC SDK; it sits beside libnfc, MFOC, Proxmark-oriented tooling, and other MIFARE Classic analysis utilities.
