Read the contents of the tag using the libnfc standard tool nfc-mfclassic, using the generated keys, saving it into kanan-dump.mfd. eml2mfd.py kanan-keys.eml kanan-keys.mfd Save that to kanan-keys.eml and convert it to a MIFARE Dump file using eml2mfd.py./infsha.py 045d60ba4f4880 -eml > kanan-keys.eml That is the same key A (also B), plus the UID, written "in place", where they'd be in a hexadecimal dump of the tag. The sample algorithm implementation can output a hexadecimal, Proxmark emulator format (EML), which we can convert./infsha.py 045d60ba4f4880 -eml To use this key with the libnfc MIFARE tools, it needs to be in a MIFARE Dump format. Reading the data from an Infinity NFC toy That is the key A used for all five sectors, necessary to read or write the Infinity NFC toy, generated algorithmically, instead of sniffing.
Generating the keys for an Infinity NFC toy The UID of this figure is 04 5d 60 ba 4f 48 80. NFC device: SCM Micro / SC元711-NFC&RW openedĪn ATQA of 00 44 with an SAK of 09 means a Disney Infinity NFC toy. (This is the same as for any MIFARE tag.) nfc-list Here's the output of the libnfc standard tool, nfc-list, when run against the "Kanan Jarrus" figure used in the demo. You may also want the emlinsert.py Python 2 program, which makes it easier to create the file necessary to write custom data to an NFC tag, listed at the bottom of this page. Download the eml2mfd.py and mfd2eml.py programs from the MIFARE Classic Tool source control so we can convert data back and forth. We'll be working in hexadecimal, which is easier for people to read, but the tools use the "MIFARE Dump" format. You'll need the infsha.py Python 2 program, which is an example implementation of the key generation algorithm, listed in New interoperability for Disney Infinity NFC toys. You'll also need a libnfc-supported NFC reader. Mac users may be able to use macports or homebrew, or compile it natively. Linux users should be able to install it using their package manager. Consider writing your own data only to toys you no longer wish to use with the game.
