Mifare Classic Tool 2.3.1 Jun 2026

If the keys match, the app decodes the sectors and presents a hexadecimal view of the card. Users can save this layout as a .mct or .bin dump file. Step 3: Cloning and the "Magic Card" Limitation

You need the right hardware to use this app. Not every phone will work. : Your phone must have an active NFC chip.

MIFARE Classic Tool provides a comprehensive suite of features for managing and interacting with RFID tags:

The application features a dedicated key file manager. Users can create, edit, and save dictionaries of known keys (e.g., standard factory default keys like FFFFFFFFFFFF or A0A1A2A3A4A5 ).

The Mifare Classic 1K tag contains 16 sectors, each divided into 4 blocks. The final block of each sector is the "Sector Trailer," which stores two keys (Key A and Key B) and Access Conditions (ACLs). The security of the card relies on the proprietary Crypto1 stream cipher. mifare classic tool 2.3.1

: It includes tools to decode and encode value blocks used for credits or counters. Analysis Tools : Features include a

: Users can read tag data using "key files" or dictionaries to authenticate against different sectors. The app displays this information in various formats, such as highlighted hex or 7-Bit US-ASCII. Tag Cloning

Compatibility

: Allows you to scan and display the complete contents of an RFID tag, provided you possess the required authentication keys. If the keys match, the app decodes the

MCT allows users to perform various tasks that standard NFC apps cannot, provided they have the correct encryption keys for the target tag:

: It supports "dump-wise" writing to create clones of existing tags.

This tool allows you to analyze the access control bytes in the trailer block of each sector. It decodes which keys (A or B) are needed to read or write to specific blocks within a sector, and it can encode new permissions if you need to modify the access rights. 4. BCC Calculator (Block 0 Customization)

: Contrast two tag configurations line by line. Core Features of Version 2.3.1 Not every phone will work

: The app can interface with external NFC readers like the ACR 122U . Technical Limitations & Security While robust, the tool has several specific constraints: MIFARE Classic Tool - Apps on Google Play

MCT本身并不具备暴力破解或密码学漏洞攻击（如Darkside攻击）能力，因为它基于手机NFC的效率无法满足高强度计算的需求。但是，它拥有极其高效的系统。 MCT以文件的方式管理密钥库。用户可以通过“字典攻击”的方法读取卡片：将一系列已知的默认密钥（如 FFFFFFFFFFFF 、 A0A1A2A3A4A5 等）、泄露的常用密钥或通过外部工具（如MFOC）破解的密钥，编制成一个文件（.keys）。当读取卡片时，MCT会遍历这个字典，尝试使用每一个密钥去认证卡片中的扇区。一旦匹配成功，MCT就会利用该密钥解密并读出该扇区的数据，或者利用已知的A密钥去配合读取B密钥。

It provides tools to decode/encode Access Conditions and Value Blocks .

Block 0 of Sector 0 contains the Unique Identifier (UID) and manufacturer data. On original cards, this block is permanently locked at the factory.

The tool acts as a portable reader/writer that allows users to: Read and Write
