Lizenzierung in Jeder Sprache

Die Auris Licensing API ist eine Standard-REST/JSON-API. Du brauchst kein SDK — jede Sprache, die einen HTTP-POST senden und JSON parsen kann, kann Lizenzen validieren, Geräte aktivieren und Features steuern.

Wenn du JavaScript/TypeScript verwendest, nutze stattdessen das @auris/js SDK — es verwaltet Offline-Fallback und Widerrufs-Caching automatisch.

Der Einzige Endpoint, Den Du Brauchst

POST https://your-auris-domain/api/licensing/validate


// Request
{
  "key": "VIG-A8BC-D3EF-G4HJ-K5LM"
}
 
// Response (valid)
{
  "valid": true,
  "features": ["threat-intel", "vuln-scan"],
  "seats": { "used": 1, "max": 5 },
  "expiresAt": "2027-03-15T00:00:00Z"
}
 
// Response (invalid)
{
  "valid": false,
  "reason": "EXPIRED"
}

Header: Content-Type: application/json und x-tenant: your-tenant (optional, Standard ist altovar).

Kein Bearer-Token erforderlich. Dies ist ein öffentlicher Endpoint.

Sprachbeispiele

C#

C# (.NET)


using System.Net.Http;
using System.Text;
using System.Text.Json;
 
public record LicenseResult(bool Valid, string? Reason, string[]? Features, DateTime? ExpiresAt);
 
public class AurisLicense
{
    private static readonly HttpClient _http = new();
    private readonly string _baseUrl;
    private readonly string _tenant;
 
    public AurisLicense(string domain, string tenant = "altovar")
    {
        _baseUrl = $"https://{domain}";
        _tenant = tenant;
    }
 
    public async Task<LicenseResult> ValidateAsync(string key)
    {
        var request = new HttpRequestMessage(HttpMethod.Post, $"{_baseUrl}/api/licensing/validate")
        {
            Content = new StringContent(
                JsonSerializer.Serialize(new { key }),

Verwendung:

// Validate
var result = await license.ValidateAsync("VIG-A8BC-D3EF-G4HJ-K5LM");
if (result.Valid)

}
 
// Activate device
await license.ActivateAsync("VIG-A8BC-D3EF-G4HJ-K5LM", GetMachineId(), Environment.MachineName);
 
// Feature gating
if (result.Features?.Contains("threat-intel") == true)
{
    // Enable threat intel module
}

curl

Zum Testen oder für Shell-Skripte:


# Validate
curl -s -X POST https://auth.yourdomain.com/api/licensing/validate \
  -H "Content-Type: application/json" \
  -H "x-tenant: altovar" \
  -d '{"key": "VIG-A8BC-D3EF-G4HJ-K5LM"}' | jq
 
# Activate device
curl -s -X POST https://auth.yourdomain.com/api/licensing/activate \
  -H "Content-Type: application/json" \
  -H "x-tenant: altovar" \
  -d '{"key": "VIG-A8BC-D3EF-G4HJ-K5LM", "fingerprint": "abc123", "name": "Dev Machine"}'
 
# Deactivate device
curl -s -X POST https://auth.yourdomain.com/api/licensing/deactivate \
  -H "Content-Type: application/json" \
  -H "x-tenant: altovar" \
  -d '{"key": "VIG-A8BC-D3EF-G4HJ-K5LM", "fingerprint": "abc123"}'

Offline-Validierung (JWT)

Wenn ein Schlüssel ausgestellt wird, enthält er ein jwtToken — ein signiertes JWT mit den Berechtigungen. Für die Offline-Validierung ohne SDK dekodiere den JWT-Payload (base64url) und prüfe:

Ablauf: Der exp-Claim (Unix-Zeitstempel) muss in der Zukunft liegen
Widerruf: Rufe periodisch /api/licensing/revocation-list ab und prüfe, ob die jti des JWT in der Widerrufsliste steht
Berechtigungen: auris_lic.features, auris_lic.seats.max, auris_lic.devices.max


// JWT payload (decoded)
{
  "jti": "key_abc123",
  "iss": "auris",
  "sub": "VIG-A8BC-D3EF-G4HJ-K5LM",
  "exp": 1804723200,
  "auris_lic": {
    "features": ["threat-intel", "vuln-scan"],
    "seats": { "max": 5 },
    "devices": { "max": 3 }
  }
}

Für eine vollständige Offline-Validierung mit Signaturprüfung verwende den öffentlichen Auris-Schlüssel von /.well-known/jwks.json. Die meisten Sprachen haben JWT-Bibliotheken (z.B. System.IdentityModel.Tokens.Jwt für C#, Crate jsonwebtoken für Rust, golang-jwt für Go).

Geräte-Fingerprinting

Für gerätebasierte Lizenzierung erstelle eine stabile Maschinenkennung:

Sprache	Methode
C#	`System.Management` → `Win32_ComputerSystemProduct.UUID` oder `Environment.MachineName`
Rust	Crate `machine-uid` oder `/etc/machine-id` unter Linux
C/C++	`/etc/machine-id` (Linux), `IOPlatformUUID` (macOS), Registry `MachineGuid` (Windows)
Go	`github.com/denisbrodbeck/machineid`
Python	`uuid.getnode()` oder `platform.node()`
Java	`InetAddress.getLocalHost().getHostName()` + MAC-Adresse

Der Fingerprint muss lediglich ein stabiler, für die Maschine eindeutiger String sein. Sende ihn an activate und deactivate.

Zusammenfassung

Das Muster ist in jeder Sprache gleich:


1. POST /api/licensing/validate  {"key": "..."}  → {valid, features, seats, ...}
2. POST /api/licensing/activate  {"key": "...", "fingerprint": "..."}  → 200 OK
3. POST /api/licensing/deactivate  {"key": "...", "fingerprint": "..."}  → 200 OK

Drei Endpoints. Kein SDK erforderlich. Kein API-Key. Kein Bearer-Token. Nur HTTP + JSON.
