PostQuantum.DataProtection.Testing

License: MIT

Test fakes for PostQuantum.DataProtection. Write unit tests against your own code that consumes the PQ data-protection chain, without standing up a real ML-KEM keypair, a real classical KEK, or a real file on disk.

⚠️ Preview (0.1.0-preview.4). Tracks the core PostQuantum.DataProtection preview cadence.

Install

dotnet add package PostQuantum.DataProtection.Testing --prerelease

Use it

using Microsoft.AspNetCore.DataProtection;
using Microsoft.Extensions.DependencyInjection;

[Fact]
public void My_service_protects_and_unprotects_round_trips()
{
    var services = new ServiceCollection();
    services.AddPostQuantumDataProtectionTesting();   // ← the one line
    using ServiceProvider sp = services.BuildServiceProvider();

    IDataProtectionProvider dp = sp.GetRequiredService<IDataProtectionProvider>();
    IDataProtector protector = dp.CreateProtector("my.purpose");

    string protectedToken = protector.Protect("hello");
    string roundtripped = protector.Unprotect(protectedToken);

    Assert.Equal("hello", roundtripped);
}

AddPostQuantumDataProtectionTesting() wires:

  • A LocalContentKeyProvider with a fixed test passphrase at the smallest Argon2id work factor.
  • A FakePostQuantumKeyStore (in-memory, no disk I/O).
  • A PostQuantumKeyManager bound to both.
  • AddDataProtection() configured with the PQ encryptor in Hybrid mode.

The chain generates a fresh ML-KEM-768 keypair on first use, wraps the secret key under the host KEK, and persists everything in memory only. Tests are isolated from each other because the service provider scopes the fakes.

When NOT to use this

  • End-to-end tests of the PQ chain itself. The core repo's tests/PostQuantum.DataProtection.Tests already does that; you don't need to.
  • Tests that pin file-format compatibility. Use FilePostQuantumKeyStore against a temp directory instead.
  • Tests that hit a real cloud Key Vault. Use the real PostQuantum.DataProtection.AzureKeyVault store against a test vault.

The fakes here are for your tests, against your code that consumes the abstraction. They are deliberately tiny and stateless.

0.1.0-preview.4: First public preview. Test fakes for PostQuantum.DataProtection. Ships FakePostQuantumKeyStore (in-memory IPostQuantumKeyStore) and a one-line DI helper (AddPostQuantumDataProtectionTesting) so consumer projects can write unit tests against their own code without standing up a real ML-KEM keypair, a real classical KEK, or a real file on disk.
