Cross.Identity

A .NET identity and authentication library: configurable scenarios (registration, sign-in, password recovery, token issuance and refresh), JWT, Argon2, email/SMS verification, and a process engine with JSON-defined flows.

Features

  • Process Engine — runs scenarios (flows) from JSON definitions with sequential steps.
  • Flows — registration, password/code sign-in, forgot password, token, refresh token, get user, request and verify codes (email/SMS).
  • JWT — issue and validate access/refresh tokens, configurable claims and lifetimes.
  • Security — password hashing (Argon2), one-time codes, phone normalization.
  • Channels — email and SMS (code delivery via Cross.Messaging).
  • External OAuth — Google, Microsoft, GitHub, Apple; OAuth state in the database (auth.ExternalLoginStates), multi-instance without sticky sessions.
  • Forms — declarative field definitions and validation rules (equal, requiredIf, atLeastOneRequired, etc.).
  • Licensing (JWT) — Peshkov license key check on the first flow call; without a key in dev/test, execution continues with a warning in logs.

Requirements

  • .NET 8.0

Usage

  1. Registration in the application (ASP.NET Core):
services.AddCrossIdentity(configuration);
// Registers: IFlowExecutor, StepRegistry, all IStepFactory, UserService, CodeService, JwtTokenService,
// LicenseAccessor, LicenseValidator, ILicenseProductInfo, definition providers (files + embedded), forms, etc.

License key (optional) — CrossIdentity section in configuration or the CrossIdentity__LicenseKey environment variable:

{
  "CrossIdentity": {
    "LicenseKey": "<license key here>"
  }
}

Validation runs automatically on the first call to IFlowExecutor.ExecuteAsync — no extra code required. Keys: peshkov.biz.

Behavior:

Scenario Result
Key not set LogCritical, flow runs (dev/test)
Invalid JWT LogError, flow runs
Expired / wrong product type LogError + LogCritical, flow runs
Valid key LogInformation with edition and expiration date
  1. Running a scenario — in a controller or minimal API, pass the request body as a dictionary and call:
var result = await _flowExecutor.ExecuteAsync(
    input: requestBodyAsDictionary,
    flow: "license",           // e.g. license, game, shop, edoctors
    operation: FlowOperationEnum.Token,
    cancellationToken);
// result.Data — dictionary of fields from the collectResult step (e.g. access_token, refresh_token, LastCode).
  1. Flow definitions — JSON in ProcessEngine/Definitions/Flows/ (and optionally from the file system). File names: {flow}.{Operation}.json (e.g. license.Token.json, game.Register.json). See FLOWS.md for detailed flow and step documentation.

Dependencies (NuGet)

  • Cross.ErrorHandlers
  • Cross.Headers
  • Cross.Messaging
  • Cross.PepperVault

Build and tests

dotnet build
dotnet test

Tests

Categories (NUnit)

Constants — Cross.Identity.Tests.Common.TestCategory, attributes: [Category(TestCategory.UNIT)], [Category(TestCategory.INTEGRATION)], [Category(TestCategory.FUNCTIONAL)].

Category Purpose
UNIT Mocks, single component, no InMemory EF
INTEGRATION EFTestsBase (InMemory EF + real services), RunFlowCommandHandlerTestsBase / Identity/FlowTests (end-to-end process engine)
FUNCTIONAL Reserved (E2E / TestServer / external dependencies), not used yet

Run examples:

dotnet test --filter "Category=Unit"
dotnet test --filter "Category=Integration"

Method naming

Given_When_Then convention:

  • Given — context/preconditions.
  • When — action.
  • Then — expected result.

Example: ExistingUser_RequestCode_SendsCodeAndReturnsLastCode.

Layout: Cross.Identity.Tests/Identity/ — FlowTests (integration), StepTests and StepFactoryTests (unit); Services/ — unit or integration depending on the base class (EFTestsBase → integration).

ToDo

  • Migrate from System.IdentityModel.Tokens.Jwt to Microsoft.IdentityModel.JsonWebTokens
