DRGSS: .net RPG Maker XP/VX Encrypter/Decrypter

[vgvgf]

After this joke [April Fools] RPG Maker XP/VX Decrypter, I said at this comment that I would make a real Decrypter.

So, I have done one, in c#.net. It alows batch proccessing and other features. I have also made an encrypter, it seems to work, but I haven't tested it much yet.

---> Download v1.1C - Cool Music Version <---


---> Download v1.1 <---


You will need .net framework 3.5 for running it.

Special Thanks to leexuany, for his WX RGSSAD, the base for this project.

Nice, any source release?

EDIT:


It works pretty well, theres only one problem. With your RMXP Project file creator, its an unreadable format for RMXP, so everytime i decrypt something i have had to move a project file over to fix this. Just letting you know :grin:

No music :sad:

Good work vgvgf's. I wasn't sure whether you were serious or not.
I haven't tested it, but I have full confidence that it works ^^
I look forward to a version with music.

There are so many Decrypters but still not a single Encrypter to protect your projects ;(

I have uploaded the sources

I fixed that, thanks for reporting it.

Hehe, at first I posted that without thinking to create this, but after a while I decided to do it.


And, I have finished the c00l music version!
You will not only be able to decrypt rgssad and rgss2a files, but also to hear some cool music that will make you happier!

Why the HELL would ANYONE except rip-off artists be excited about this? You just tore away the last shreds of protection we had against piracy from lazy dumbasses and now NO ONE in their right minds would ever try to put out a custom game. I sure hope you are satisfied with yourself, saboteur!!!

Rico, chill.

What if you lost your game in a crash and had to start again from a different, older, distribution? I'm not sure if RMXP uses passwords to encode the data, but if it does, it obviously doesn't matter in this case.

Besides, they obviously never had that great of protection anyway.

If a real rip-off artist wanted to, they would just ask their cracker buddy to break the encryption for them.

 

[Glitchfinder]

Not only that, but there were already two partial decrypters out there.

Anyway, this is really cool. *downloads before vgvgf removes from the internet*

Ok just an idea, but could prove useful.

Any way of changing the Magickey for a project to be encrypted with a diffrent key? that way stoping decryptors from using this without the key. Why? the answer is simple.

It will allow the orignal creator to only extract it, other than the talented people who know how to do it, but still it will hinder script kiddies.And will act against other decryptors, basicly minimzing the use of this program for theft...

You know that there was a decryptor for RMXP/RMVX games since lot time ago, don't you? I have posted about it at 19-12-2008, long time ago, and lots of games are still being created. viewtopic.php?f=6&t=59983

What do you mean with that? I'm not planing to remove this from the internet. Just curious :P

The problem is that the 0xDEADCAFE key is stored in the RGSS dll. If you encrypt the files with another key, you have to modify the RGSS dll too, so it can read the data. But if the key is in the dll, anyone with a hex editor can find it and just use it for decrypting.
Maybe if the dll is encrypted after modifing the key, it would be harder to find, and that could stop lot of people.
I will see what can I do.

 

[Alexander Morou]

Yes, basically the problem lies in the fact that the program uses a hard-coded encoding system with a singular magic-key. They didn't include the option of using a different key. You'd have to hack the system yourself in order to use a different key, which would require, in itself, a different program to encode the data with the new key (unless RGSS.dll does both encoding and decoding, then just changing the library you use to encode and distributing that same library with your game should be enough).

You still run into the same issue that this points out: anyone with enough knowledge can obtain whatever key you use, even if you encrypt the dll. Because in the end, it's all about the method itself. The encryption method used by RMXP isn't very good, which is why it's so easy to reverse.

lol, man, even I'm not that upset about it XD.

Obviously I'm not thrilled about this, but like you said it's not the first one. At least this one apparently has some music for you to listen to XD

The reason I say that is because, after several exhaustive searches, I have concluded that the only way to get a copy of the other two decrypters is to ask the creator, or get it from someone else. None of the links worked, including ones on the Web Archive.

 

[vgvgf]

@Alexander, that's right. It seems Enterbrain made it difficult to the users to protect their games.

@DeM0nFiRe, haha, the c00l music makes it much better :biggrin:

@Glitchfinder, one of the decryptors is WX RGSSAD for leexuany, which I posted here: viewtopic.php?f=6&t=59983
Both links still work. But what about the other decryptor you mentioned?

It's been well over a year since the last time I did one of those searches, so I can't remember the name. But I seem to remember two different decrypters having been created, then removed by the creator after people continued to demand they be taken offline because they didn't want their projects decrypted. I'm pretty sure the last time I searches was before that post was made, actually.

awesome, now I gotta find a second encrypter to make sure people wont steal my resources. :blush:

Problem is, you'd still end up using an RPG-Maker Game.exe and RGSS.dll, unless someone decides to fully remake it... oh wait.

Anyway, until such a time exists where a better encryption algorithm is available to RPG Maker XP/VX users, you're pretty much just out of luck. Since using a second encryption method would render the files useless to RPG Maker XP without some script that's easily attainable (with this method) that handles the decryption algorithm.

 

[valdred]

which makes it even more unethical to create this application :|:

 

[vgvgf]

I have added .rgssad/.rgss2a encryption to the project I have updated the links in the first post, including the sources.

Btw, I don't recommend using the C00l Music version for encryption of projects. Decryption is cooler than encryption, so the music should be reserved only for decrypting projects.

Oh, ok so now that the entire safety net for non-lazy creative people is destroyed, you're giving us band-aid to fix it? Oh boy be still my heart I can hardly hold back my enthusiasm. If I ever found the slimy sonuvabeech what broke Enterbrain's encryption I'd beat 'em with a baseball bat. Cracking a protection system "just because I can" is about as lame as you can get.
