MFCUK - MiFare Classic Universal toolKit

Toolkit containing samples and various tools based on and around libnfc and crapto1, with emphasis on Mifare Classic NXP/Philips RFID cards.

Special emphasis of the toolkit is on the following:

mifare classic weakness demonstration/exploitation
demonstrate use of libnfc (and ACR122 readers)
demonstrate use of Crapto1 implementation to confirm internal workings and to verify theoretical/practical weaknesses/attacks

Wishlist for next version:

~~integrate with mifarecrack (proxmark3 sniffed-logs parser-decrypter) (short-term)~~
write proper proxmark3 parser (c for internal calls and py for external calls)
integrate with MFOC (medium-term)
integrate with crapto1 3.2
~~create initial fingerprint design&implementation. card fingerprinting based on: known plain-text in specific blocks, range of UIDs, etc. (short-term)~~
more templates to add (short-term)
summarize decoding info and implement custom decoders (short-medium-term)
implement "wiser" template data-structure and appropriate binary data similarity algotihms (medium-term)
have command-line (silent+interactive) and GUI (QT-based?) (long-term)

More of research type long-term activity (any volunteers :)?):

go deeper into how UID/block/keys/Nt/Nr relate so that we choose Nt and Nr with shortest crack time (long-term)
research on how to shorten time in case prefix of the keys or any part of the keys are known
many cards from same issuer might have known plaintext in specific blocks - can this be exploited to speed-up first key recovery and then use optimized darkside/nested to get whole card (medium-term)

IMPORTANT NOTICE - would greatly appreciate if someone can donate (even used, smashed, but still programmable) things below:

either Nokia 6131 either Nokia 6212
iCarte for iPhone

These things are aimed to research, implement the 100% software emulation of Mifare Classic Cards (including UID) and release it open-source under GPL.

Please contact zveriu through my zveriu's blog regarding donations.
