Edit file modules/Licensing/Module.php

In protected function getKeyInfo(), after $this->keyInfo = $oKI->GKI($sKey); add var_export($this->keyInfo); exit;

Add a trial key to data/settings/config.json

Add $this->keyInfo = [...]; in place of your var_export & exit with fixed content.

Enjoy ;)

ps : I wouldn't have bothered to post that if afterlogic had allowed a single or two user with full features by default

I think this is not working anymore in 9.7.1

Maybe a replay attack can be done by replacing KI.php and license file with an old one from : afterlogic/aurora-module-licensing@e30a52f#diff-a8b460e8fea5607a2b05effa9f6512e5271f1e26ca6ab7890c7eab58cfc1e54c

Or someone may develop a replacement from unobfuscated KI.php https://www.unphp.net/

Or create a new generator with a self-generated public/private key pair and replace modules/Licensing/classes/AU80.key

Wasted 2 hours on that, so better save all vectors

ps : If you like their product please send them some money if you are not poor like me :)

Unobfuscate is really just rename variable using hex editor, format the code and debug using xdebug. you just return correct array from KI.php
