ARCHERGATE / SDK

Machine-bound keys for Unity assets and tools.

Archergate links directly into your native plugin or wraps your managed assembly. Keys bind to the machine on first activation. No user accounts. No Unity Asset Store dependency.

The problem with Unity asset distribution

The Unity Asset Store terms allow buyers to use assets on any project they own, but redistribution is prohibited. In practice, enforcement is your responsibility. Buyers share .unitypackage files in Discord servers. Cracked shader packs circulate on forums. Without machine binding, the only thing stopping redistribution is an honor system.

Archergate adds hardware-level enforcement. A license key activated on machine A cannot be used on machine B. The fingerprint is derived from CPU identity and OS installation ID — stable across reboots, unique per hardware configuration.

Integration options

Unity does not support native code in every context, but there are two clean paths depending on what you are shipping:

// Place archergate_license.dll (Win) or libarchergate_license.dylib (Mac) in Assets/Plugins/
using System.Runtime.InteropServices;

public static class LicenseGate
{
    [DllImport("archergate_license")]
    static extern System.IntPtr ag_license_new(string apiKey, string appId);

    [DllImport("archergate_license")]
    static extern int ag_license_validate(System.IntPtr client, string key);

    [DllImport("archergate_license")]
    static extern void ag_license_free(System.IntPtr client);

    public static bool Validate(string licenseKey)
    {
        var client = ag_license_new("your-api-key", "com.you.toolname");
        int rc = ag_license_validate(client, licenseKey);
        ag_license_free(client);
        return rc == 0;
    }
}

[InitializeOnLoad]
public static class ToolLicenseCheck
{
    static ToolLicenseCheck()
    {
        string key = EditorPrefs.GetString("MyTool_LicenseKey", "");
        if (!LicenseGate.Validate(key))
        {
            EditorUtility.DisplayDialog(
                "License Required",
                "Enter a valid license key to use this tool.",
                "OK"
            );
            // Open license entry window
            LicenseWindow.ShowWindow();
        }
    }
}

What ships in the SDK

Header and download

The archergate_license.h header and pre-built binaries are available on GitHub Releases. No build system required — link the library, include the header, call three functions.
