DKNet.EfCore.DataAuthorization

A .NET library for secure, multi-tenant data authorization in Entity Framework Core. Enables automatic filtering of data based on ownership, supports DDD and API scenarios, and is designed for extensibility.

Features

  • Automatic global query filtering based on data ownership keys
  • Interfaces for associating entities with owners (IOwnedBy), providing ownership keys (IDataOwnerProvider), and integrating with DbContext (IDataOwnerDbContext)
  • Extension methods for easy setup via dependency injection (EfCoreDataAuthSetup)
  • Support for multi-tenancy and secure data isolation
  • .NET 9.0 compatible

Installation

Add the NuGet package to your project:

dotnet add package DKNet.EfCore.DataAuthorization

Usage

Register the data authorization provider and setup in your DI container:

using Microsoft.Extensions.DependencyInjection;
using DKNet.EfCore.DataAuthorization;

services.AddAutoDataKeyProvider<MyDbContext, MyOwnerProvider>();

Implement IOwnedBy on your entities:

public class Document : IOwnedBy
{
    public string? OwnedBy { get; private set; }
    public void SetOwnedBy(string ownerKey) => OwnedBy = ownerKey;
}

Implement IDataOwnerProvider to supply ownership keys and accessible keys:

public class MyOwnerProvider : IDataOwnerProvider
{
    public IEnumerable<string> GetAccessibleKeys() => ...; // e.g., from user context
    public string GetOwnershipKey() => ...; // e.g., current user's tenant key
}

API

  • EfCoreDataAuthSetup.AddAutoDataKeyProvider<TDbContext, TProvider>(IServiceCollection): Registers automatic data key management for a DbContext.
  • IOwnedBy: Interface for entities supporting ownership, with methods to get/set the owner key.
  • IDataOwnerProvider: Interface for providing accessible keys and ownership key for new entities.
  • IDataOwnerDbContext: Interface for DbContexts supporting data authorization, exposing accessible keys.
