Diversification\n\nWriter takes 16-byte 2K3DES master key as command line argument, derives from it \na new key based on UID of the tag, and then writes the new key to the tag. \nIf second argument is provided, then it's used as the current key. \nIf no second argument is provided, then the default key (BREAKMEIFYOUCAN!) is used.\n\nReader takes master key and reads the whole card with derived key.\n\nThis works only for Mifare Ultralight C tags.\n\n## Dependencies\nI use [clausecker/freefare](https://github.com/clausecker/freefare) \nthat supports key diversification and has some ad-hoc fixes to work with latest\n version of [libfreefare](https://github.com/nfc-tools/libfreefare) (as well as some minor bug fixes).\n \nObviously this means that building and installing [libnfc](https://github.com/nfc-tools/libnfc/) and \n[libfreefare](https://github.com/nfc-tools/libfreefare) from \nmaster is needed too. I'd have provided a specific version that's required, but \nfor some reason they have decided \nto not bump the version for the past 4 years despite continuous changes to the API, \nso expect things to be broken.\n\n## Usage\n```\nsh build.sh\noutput/writer 00112233445566778899AABBCCDDEEFF FFEEDDCCBBAA99887766554433221100\noutput/reader 00112233445566778899AABBCCDDEEFF ","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgraynk%2Fdiversify","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgraynk%2Fdiversify","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgraynk%2Fdiversify/lists"}
