TqrLabKit.SmartCard.Desfire

A .NET library for working with DESFire smart cards using PC/SC compatible readers. Tested with MIFARE DESFire EV3.

Still under active development, feedback and contributions are welcome.

Install

dotnet add package TqrLabKit.SmartCard.Desfire

Quick usage

Get full example on GitHub

using PCSC;
using PCSC.Iso7816;
using TqrLabKit.SmartCard.Desfire.Commands;

var ctx = ContextFactory.Instance.Establish(SCardScope.System);
var reader = ctx.GetReaders()[0];
using var iso = new IsoReader(ctx, reader, SCardShareMode.Exclusive, SCardProtocol.Any);
var df = new DfCommands(iso);

// Get version, select application
var version = df.GetVersion();
df.SelectApplication(new byte[]{0x00,0x00,0x00});

// Authenticate with one of:
// df.AuthenticateNative(keyNo, keyBytes);
// df.AuthenticateIso(keyNo, keyBytes);
// df.AuthenticateAes(keyNo, keyBytes);

// Change master key:
// df.ChangeMasterKey(authType, sessionKey, newKey[, keyNo]);

Known Issues

  • If the session was established using ISO authentication with a DES/2K3DES key, changing the master key is currently unsupported. Use AuthenticateNative instead.

Roadmap

  • Stabilize public API
  • Add unit/integration tests against mock hardware (yes, the current test is using real hardware)
  • Improve docs and per-key-type examples
  • Add more commands

Note: public API (method signatures, enums) may evolve between minor releases to improve ergonomics.

Contributing

PRs and issues welcome. Keep changes focused and include tests when applicable.
