Asgard.Heimdall.JwtSigning

Lightweight JWT signing for small Asgard-based projects.

This package is for projects that use the Asgard framework but do not want to hand-build JWT claims. It signs access tokens that follow the Asgard identity claim contract from Asgard.Abstractions.Identity.

What It Does

  • Issues JWT access tokens with Asgard-compatible claims.
  • Uses AsgardClaimTypes from Asgard.Abstractions.
  • Supports user tokens and backend service tokens.
  • Supports RSA signing and symmetric signing.
  • Produces JWKS metadata for the current signing key.

What It Does Not Decide

The application still owns its own identity logic:

  • login endpoint
  • password or external credential validation
  • role and permission lookup
  • refresh token behavior
  • token revocation or blacklist behavior
  • tenant-specific key storage or rotation

Those can be implemented by the application when needed. This package only prevents every small project from reimplementing the Asgard JWT shape by hand.

Basic Usage

var issuer = new AsgardJwtIssuer(new AsgardJwtSigningOptions
{
    Issuer = "https://auth.example.com",
    Audience = "asgard-api",
    KeyId = "main-key",
    RsaPrivateKeyPem = privateKeyPem,
    RsaPublicKeyPem = publicKeyPem
});

var token = issuer.Issue(new AsgardJwtSubject
{
    Subject = user.Id,
    UserId = user.Id,
    TenantId = tenantId,
    Roles = roles,
    Permissions = permissions,
    Scope = ["api"],
    UserMetadatas = userMetadatas,
    TenantMetadata = tenantMetadata
});

Backend Service Token

var token = issuer.Issue(new AsgardJwtSubject
{
    Subject = "orders-worker",
    ClientId = "orders-worker",
    TokenType = AsgardJwtConstants.BackendServiceTokenType,
    Scope = ["jobs.execute"]
});

Backend service tokens must include client_id and must not include user_id.
