After a fairly comprehensive search, it would turn out that there is no real and reliable way to hide the code in the Oracle database (i.e. protect the code of routines, functions, packages, and triggers).
Obfuscation (WRAP), although initially promising, turned out to be useless, since UNOO is very easy to obfuscate and return the source (readable) code.
So, before I give up, is there a way supported by Oracle that really hides code? (I mean, besides blocking access using credentials).
