Kompilieren mit Schlüssel zur Skript-Verschlüsselung¶
The export dialog gives you the option to encrypt your scripts with a 256-bit AES key when releasing your project. This will make sure your scripts are not stored in plain text and can not easily be ripped by some script kiddie.
Of course, the key needs to be stored in the binary, but if it's compiled, optimized and without symbols, it would take some effort to find it.
For this to work, you need to build the export templates from source, with that same key.
Warnung
This will not work if you use official, precompiled export templates. It is absolutely required to compile your own export templates to use PCK encryption.
Schritt für Schritt¶
Generate a 256-bit AES key in hexadecimal format. You can use the aes-256-cbc variant from this service.
Alternatively, you can generate it yourself using OpenSSL command-line tools:
openssl rand -hex 32 > godot.gdkey
The output in
godot.gdkey
should be similar to:# NOTE: Do not use the key below! Generate your own key instead. aeb1bc56aaf580cc31784e9c41551e9ed976ecba10d315db591e749f3f64890f
Sie können den Schlüssel generieren, ohne die Ausgabe in eine Datei umzuleiten, aber auf diese Weise können Sie das Risiko, den Schlüssel preiszugeben, minimieren.
Set this key as environment variable in the console that you will use to compile Godot, like this:
export SCRIPT_AES256_ENCRYPTION_KEY="your_generated_key"
set SCRIPT_AES256_ENCRYPTION_KEY=your_generated_key
$env:SCRIPT_AES256_ENCRYPTION_KEY="your_generated_key"
Compile Godot export templates and set them as custom export templates in the export preset options.
Set the encryption key in the Script tab of the export preset:
Exportieren Sie das Projekt. Das Spiel sollte jetzt mit verschlüsselten Skripten laufen.
Fehlerbeseitigung¶
If you get an error like below, it means the key wasn't properly included in your Godot build. Godot is encrypting the scripts during export, but can't read them at runtime.
