Once you have decrypted_dump.mfd , you open it in a hex editor or a specific decoder tool.
: The primary purpose of these programs is to crack the hexadecimal keys that protect individual sectors of a card. Once the keys are decoded, the user can dump the card's data, modify it (such as changing balance values or access permissions), and write it to a new card.
These tools, often featured on platforms like Smartcard Focus, were widely used in 2021 for reading UID/data from RFID/NFC tags and integrating them into desktop or cloud applications. Key Features of Effective 2021 Smartcard Decoding Software

The Proxmark3 platform, particularly utilizing the Iceman fork firmware and software client, was the gold standard for RFID and contactless smartcard decoding in 2021. The software allowed users to run high-level commands to automatically crack, decode, and clone older generation smartcards, such as MIFARE Classic 1K cards, by exploiting known cryptographic vulnerabilities (like the nested and hardnested attacks).

Most decoding software relies on the API. This standard integration layer allows the software to communicate with any USB or serial smartcard reader natively, regardless of the hardware manufacturer. 2. Protocol Analyzers
