Verschlüsselte Dateien sehen wie folgt aus:

Im M2 Client werden die Python files in dieser verschlüsselten Form im Speicher abgelegt und dann bei Bedarf, wenn das Script aufgerufen wird z.B., wieder entschlüsselt.

Zur Verschlüsselung der Dateien habe ich eine Konsolenanwendung, welche nach dem erfolgreichen Verschlüsseln den generierten Schlüssel und IV fertig für Copy/Paste ausgibt.

Code

!!!Copy your key and Initialization Vector!!!
std::string base16Key = "7F7C4F8D6ECBD51E66978B9BACE0CDB4C8F9D86FF5EBF78D71828267F923E53E";
std::string base16IV = "ADF8CAB62A245425F46DDB8230D6D8C4";

Die beiden Strings müssen dann im EterPackManager Header ausgetauscht werden. Siehe dazu den Client Source.

Die Anwendung zum Verschlüsseln Bitte melden Sie sich an, um diesen Link zu sehen. Beachtet die Readme Datei.

Für die Entschlüsselung lasse ich euch den Code hier im Spoiler.
