Not much to say here other than the title. 

Since forever I've been messaged by people to crack their protected l2j private packs or remove protection from packged features.

It's pretty fun to do those things so I thought I would open a thread.

 

If you have a project or a feature that has any type of protection just message me with the protected project and I will crack it for you for free.

both of these didn't do anything to protect their "license system", i mean not a lot you can do with jars but at least obfuscate names so it takes longer than 10secs to find all "license" occurrences lmao

The lucera uses both obfuscation and string encryption for the licensing system. Even fully obfuscated it would be really easy to crack.

Lucera Latest or an old version?

No idea, the one that the guy posted. Any version is crackable.

license code is 1 class in L2PCInstance, most of which is perfectly readable, string "encryption" in this form is just wasted effort as you can decrypt any value in runtime yourself, and that's if your ever needed to, here its some basic http check, basically you can trash most of it without even reading what it does xD

That's part of it there is another part with SmartGuard as well but yeah it's just fake stuff to make it look like hard work and discourage you. Even if it was fully obfuscated it would still be exactly the same difficutly to crack it though. If you don't believe me just throw any project that you want at me and I'll deal with it.

i know it will be still simple, just breakpoint on http request to their license check endpoint and traceback nop'ing everything on the way.

Java is fucked by design here, my point was they did absolutely 0 effort here :P

 

but i support your topic, L2j was always trash not worth a penny

Even if he will obfuscated? :troll:

 

Just create a topic with guide how decompile and searching a lisence section. And how create fake project for building few changed classes and replacing their from target jar.

 

P.S. For Java exists yGuard obfuscator. This enough for avoid any cracks but need perfect Java knowledge aswell. Ofc for L2J community it's useless.

What you said is actually overkill. You don't even need to do any of that. You just remove the call to the method to begin with and there is no check lol.

You can still crack anything with an obfuscator. yGuard and Proguard will mess the source up but you can still easily find and remove the license code without any effort. Feel free to try me.

Ofc you are right if wasted time less than price. That's the main reason why i stopped develop Universal Login server base on Java language.
