Mifare master key. This app has a very limited purpose: it can change a Default DES Master Application Key to a Default AES Master Application Key and vice versa only. MIFARE DESFire® products use a PICC/Card Master Key (CMK) and can be configured so the CMK is required to carry out specific operations such as creation/deletion of apps. A functionality like this can be useful if you are This article shows you how to change the Master Application Key on a Mifare DESFire NFC tag from DES key type to AES key type. It will try a dictionary (and KDF) attack of default keys to unlock your card, as well The application note MIFARE Classic as NFC Type MIFARE Classic Tag defines how a MIFARE Classic tag can be used to store NDEF data.
