Today, I got link to the site that allow us to unwrap PL/SQL code with online service (thanks Jože!). If you’re not familiar with PL/SQL unwrapping I would recommend Pete Finnigan famous BlackHat convention 2006 presentation, where he showed the principles to unwrap PL/SQL code. At first, I hesitated to publish link to the site, but when I saw that Google is returning link as a second hit I changed my mind:).
