You can get a dump for testing from this link: https://github.com/zhovner/mfdread/raw/master/dump.mfd
This page hosts a formal specification of Mifare Classic RFID tag dump using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
All parsing code for Java generated by Kaitai Struct depends on the Java runtime library. You have to install it before you can parse data.
The Java runtime library is published in the Maven Central Repository. Refer to the artifact page for instructions how to add it into your project with the build tool that you use.
Parse a local file and get structure in memory:
MifareClassic data = MifareClassic.fromFile("path/to/local/file.mfd");
Or parse structure from a byte array:
byte[] someArray = new byte[] { ... };
MifareClassic data = new MifareClassic(new ByteBufferKaitaiStream(someArray));
After that, one can get various attributes from the structure by invoking getter methods like:
data.sectors() // => get sectors
// This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild
