You can either crack it yourself or you can buy from me.
How to crack it:
Three jars are decrypted from native code and main loader class takes control.
The java loader starts decrypting the crypted jar in relative path:
./internal/libs/SQLib.jar
and one of the interesting steps for us is the checkLicense one
CheckLicense
private void checkLicense() {
try {
SQApp.Log.debug("Verifying license.");
Brokers.init();
SQApp.Log.debug("Verifying license. Step 2");
final SQLicenser instance = SQLicenser.getInstance();
instance.setLicenceFilePath(MainApp.getDataPath() + "licenceFile.lic");
SQApp.Log.debug("Verifying license. Step 3");
try {
if (instance.licenseFileExists()) {
SQApp.Log.debug("Verifying license. Step 4");
instance.verifyLicenseFromFile();
}
}
catch (Exception ex) {
LicenseDialog.getInstance().setLicense(instance.getLastCheckedLicenseCode());
LicenseDialog.getInstance().setError(ex.getMessage());
SQApp.Log.error("License verification failed. Exc. ", (Throwable)ex);
}
LicenseDb.init(SQStructure.INTERNAL_DIR_PATH);
if (this.isRunInConsole()) {
SQApp.Log.debug("Verifying license. Step 5 CLI");
if (!SQLicenser.getInstance().verified()) {
SQApp.Log.debug("Verifying license. Step 6 CLI");
final String license = LicenseDb.getLicense();
if (license != null && !license.isEmpty()) {
SQApp.Log.debug("Verifying license. Step 7 CLI");
instance.verifyLicenseOnline(license);
}
}
}
else {
SQApp.Log.debug("Verifying license. Step 5");
while (BrowserGUI.getInstance() == null) {
SQApp.Log.info("Waiting for internal browser initialization");
Thread.sleep(500L);
}
SQApp.Log.info("License dialog initing");
BrowserGUI.getInstance().showLicenseLoadingScreen();
final String license2 = LicenseDb.getLicense();
if (license2 != null && !license2.isEmpty()) {
LicenseDialog.getInstance().setLicense(license2);
}
SQApp.Log.debug("Verifying license. Step 6");
if (!SQLicenser.getInstance().verified()) {
SQApp.Log.debug("Verifying license. Step 7");
BrowserGUI.getInstance().loadLicenseDialogForm();
SQApp.Log.debug("Verifying license. Step 8");
if (instance.isItTrial() || instance.isItPartnerTrial() || instance.isItFullMbg()) {
LicenseDb.setLicense(instance.getLicenseCode());
}
else {
LicenseDb.setLicense("");
}
}
}
if (!SQLicenser.getInstance().verified()) {
SQApp.Log.info("Missing license.");
MainApp.exitJVM();
}
SQApp.Log.debug("License was successfully verified.");
}
catch (Exception ex2) {
SQApp.Log.error("Failed to check license. Exc. ", (Throwable)ex2);
MainApp.exitJVM();
}
}You can start tracing from here to follow what’s happening:
String references are not easy to deal with because of the way Go arranges them (i.e. concatenated in blocks).
