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. Register IdentityContext in the host application. AddCrossIdentity does not register DbContext.

    IdentityContext attaches ConcurrencyStampInterceptor itself (via OnConfiguring). It rotates ConcurrencyStamp on insert/update through SaveChanges for all IHasConcurrencyStamp entities. Hosts do not need to call AddInterceptors for this.

services.AddDbContext<IdentityContext>(options =>
    options
        // SQL Server:
        .UseSqlServer(connectionString)
        // PostgreSQL: .UseNpgsql(connectionString)
        // MySQL:      .UseMySql(connectionString, ServerVersion.AutoDetect(connectionString))
        // Test:       .UseInMemoryDatabase("…")
        );

Apply the matching DDL under Infrastructure/Scripts (SqlServer, PostgreSQL, or MySQL). The EF model has no provider-specific column types; the host owns the database package and migrations.

Note: bulk updates (ExecuteUpdateAsync / ExecuteDeleteAsync) bypass interceptors; prefer tracked SaveChanges for rows that use ConcurrencyStamp.

  1. Register Cross.Identity services:
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: "main",
    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. main.Token.json, main.Register.json). See FLOWS.md for detailed flow and step documentation.

Cross.Identity: identity and authentication flows, JWT, process engine.

BREAKING: built-in flow rename license → main
- Flow id: ExecuteAsync(..., "main", operation, ...) (was "license").
- Definitions: main.{Operation}.json (was license.{Operation}.json).
- Sample/API path segment: /api/identity/main/{Operation} (was .../license/...).
- Removed demo flows: game.*, shop.*, edoctors.*.

Other breaking (same line)
- GetUser → GetUserId (enum, files, routes).
- collectResult with one field: Data is always an object, not a bare scalar.
- FlowExecutor is internal; use IFlowExecutor.

Licensing
- JWT license validation (Peshkov software) on first IFlowExecutor.ExecuteAsync call.
- Configure via CrossIdentity:LicenseKey in appsettings or CrossIdentity__LicenseKey environment variable.

Also: External OAuth, refresh-token AbsoluteExpiresAt / rotation, DeveloperMode codes.
