GrayMint.Authorization

Modular B2B Authorization Framework for .NET Applications

GrayMint.Authorization provides a flexible, multi-tenant-compatible B2B authorization framework for .NET apps. It enables role-based and resource-based access control, ideal for enterprise platforms, SaaS systems, and microservices.

🔧 Features

• Role-based and resource-based authorization
• Multi-tenant (B2B) ready
• Modular service registration and layering
• Microservice-compatible with extensible providers
• EF Core-based persistence support
• Built-in controllers and services for quick bootstrap

📦 Installation

Install the packages from nuget.org:

dotnet add package GrayMint.Authorization

🚀 Getting Started

1. Configure App Settings

• Issuer: The issuer of the tokens.
• Audience: The audience of the tokens.
• Secret: The secret key for token generation.
• Secrets: List of additional secret keys.
• CacheTimeout: The cache timeout duration.
• AllowUserSelfRegister: Boolean flag to allow or disallow user self-registration.
• AllowUserApiKey: Boolean flag to allow or disallow user API keys.
• AllowRefreshToken: Boolean flag to allow or disallow refresh tokens.
• SignInRedirectUrl: The URL to redirect to after sign-in.
• OpenIdProviders: List of OpenID providers with their respective configurations.

2. Service Registration (from Sample Web API)

var builder = WebApplication.CreateBuilder(args);
var services = builder.Services;

// Load options
var appOptions = builder.Configuration.GetSection("App").Get<AppOptions>();
services.Configure<AppOptions>(builder.Configuration.GetSection("App"));

// Register shared services and Swagger
services
    .AddGrayMintCommonServices();

// Register Authorization and Roles
builder.AddGrayMintCommonAuthorizationForApp(
    GmRole.GetAll(typeof(Roles)),
    options => options.UseSqlServer(builder.Configuration.GetConnectionString("AppDatabase")));

// Optional: Register Resource Provider
if (appOptions.UseResourceProvider)
    services.AddGrayMintResourceProvider(
        new ResourceProviderOptions(),
        options => options.UseSqlServer(builder.Configuration.GetConnectionString("AppDatabase")));

// Add EF Core & domain services
services.AddDbContext<AppDbContext>(options =>
    options.UseSqlServer(builder.Configuration.GetConnectionString("AppDatabase")));
services.AddItemServices();

3. Middleware & Execution

var webApp = builder.Build();
webApp.UseGrayMintCommonServices();
await webApp.UseGrayMinCommonAuthorizationForApp();
await webApp.Services.UseGrayMintDatabaseCommand<AppDbContext>(args);

if (appOptions.UseResourceProvider)
    await webApp.Services.UseGrayMintResourceProvider();

await GrayMintApp.RunAsync(webApp, args);

🧪 Permission Check Example

    [HttpGet("itemId/by-role")]
    [Authorize("DefaultPolicy", Roles = ["SystemAdmin", "SystemReader"])
    public Task<Item> GetByRole(int appId, int itemId)
    {
        return itemService.Get(appId, itemId);
    }

    [HttpPost("by-permission")]
    [AuthorizeAppIdPermission(Permissions.AppWrite)]
    public Task<Item> CreateByPermission(int appId, ItemCreateRequest? createRequest = null)
    {
        return itemService.Create(appId, createRequest);
    }

🧩 Extending

Implement custom providers:

• IRoleProvider
• IUserProvider
• IResourceProvider

These interfaces allow full control over how roles, users, and resources are managed.

🏗 Repo layout & CI

• src/ — the packable libraries; one shared version and package metadata via src/Directory.Build.props. pub/PubVersion.json is the version source of truth.
• tests/ — test suites and sample hosts. Never packed.
• .github/workflows/ — thin wrappers over the reusable CI in GrayMint.Common: every push to main builds, tests, bumps the version, and publishes to nuget.org; a daily job (02:30 UTC, right after GrayMint.Common's own update) upgrades all NuGet dependencies and republishes when tests pass. Nothing ships when tests fail.

Build locally:

dotnet build GrayMint.Authorization.slnx
dotnet test GrayMint.Authorization.slnx
