Hey! Thanks for the script, how did you obtain the values in secrets.env?

Hey! Thanks for the script, how did you obtain the values in secrets.env?

I extracted them from the Cryptomator APKs using https://decompiler.com and reading sources/org/cryptomator/data/BuildConfig.java for OneDrive keys, and sources/org/cryptomator/presentation/BuildConfig.java for Dropbox and PCloud keys.

Doesn't seem to work anymore, too bad.
Thanks for sharing

Go to : "domain\src\main\java\org\cryptomator\domain\usecases\DoLicenseCheck.java"
Replace the original code with this one :

	public LicenseCheck execute() throws BackendException {
	    return new LicenseCheck() {
	        public String mail() {
	            return "";
	        }
	    };
	}
