MIFARE is a series of integrated circuit (IC) chips used in contactless smart cards and .The MFRC522 is a highly integrated reader/writer IC for contactless communication at 13.56 .Encryption keys prevent data from being emitted until the MIFARE card and card reader .
The main goal. The goal here is to cover the process of cloning and editing .Due to some weaknesses in MIFARE Classic, you can retrieve all the keys (A and B) of a tag .The MIFARE® Classic family is the most widely used contactless smart card ICs operating in the 13.56 MHz fre-quency range with read/write capability and ISO/IEC 14443 A compliance. Smart cards based on MIFARE® Classic ICs are a commonly known solution in various applications such as: Access Control. Public Transportation. Electronic Toll Collection
TL;DR - It is a brute-force list of known keys for MiFare Classic tags used when trying to read those tags. You can add your own entries using the “Detect Reader” function of the Flipper in conjunction with the “Mfkey32” tool on the Flipper mobile app. I bought a lot of blank RFID Mifare 4k tags. Their default Authentication KEY A and KEY B is FF FF FF FF FF FF. Now I want to change them to something else. I'm using APDU structure. I'm sending commands like this and it works well: byte[] baData = { .Everyone who creates applications for the card has access to the UID. The Card Serial Number is specific to the application loaded on to the card. It can only be accessed by that application via an encryption key. If the card had several applications loaded on to it (unlikely but possible), then each could have a different CSN.
Mfkey32v2 calculates Mifare Classic Sector keys from encrypted nonces collected by emulating the initial card and recording the interaction between the emulated card and the respective reader. While performing authentication, the reader will send "nonces" to .
MIFARE uid vs serial number
MIFARE is a series of integrated circuit (IC) chips used in contactless smart cards and proximity cards. The brand includes proprietary solutions based on various levels of the ISO/IEC 14443 Type-A 13.56 MHz contactless smart card standard.Each sector of a MIFARE Classic card has two authentication keys: key A and key B. These two keys together with access conditions are stored in the last block of each sector (the so-called sector trailer).The MFRC522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz. The MFRC522 reader supports ISO/IEC 14443 A/MIFARE mode. The MFRC522’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A/MIFARE cards and transponders without additional active circuitry.Encryption keys prevent data from being emitted until the MIFARE card and card reader mutually authenticate each other. It’s also an RFID card because of its frequency of 13.56 MHz. MIFARE cards have three main differences from a standard proximity card: The frequency of a MIFARE card is 13.56 MHz. A standard 1386 proximity card is 125kHz.
The main goal. The goal here is to cover the process of cloning and editing RFID tags. MIFARE Classic ones especially, which are still widely used nowadays despite the many hacks found throughout the last few years. This is not intended to teach you all about RFID, NFC, and MIFARE hacking. So, before we jump in let’s learn some basics.The MIFARE® Classic family is the most widely used contactless smart card ICs operating in the 13.56 MHz fre-quency range with read/write capability and ISO/IEC 14443 A compliance.
