I share this guide with you to be able to use the Smart Crypt Decrypt code that is used to decrypt the client's files (utx, ukx and u).
The programs that you will need is Microsoft Visual Studio (in my case I will use the 2013 version, you can use other versions) and CFF Explorer.
Microsoft Visual Studio 2013: https://www.youtube.com/watch?v=VWYLqKtAXzU
CFF Explorer: https://ntcore.com/?page_id=388

Smart Crypt Decryptor Code: https://pastebin.com/Shgmywrs
Once they have these programs installed, let's continue.
First of all we open the Microsoft Visual Studio and let's FILE> New> Project or in another faster way  Ctrl + Shift + N It will show us the following We

select Visual C ++ thenWin32 Console Application and we end withOK the name is put or not, the only thing it will do is give a name to the solution, that is, if you put "juanito" when compiling the DLL it will have a name of "juanito.dll"

Then another window does not appear we give Next we select DLL and we mark Empty project and Finish

It should show us the following:

We right click on Header Files> Add> New item ...
Another window appears, with two optionsC ++ File (.cpp) and Header File (.h) select C ++ File and then OK] in this case the name is also optional to add, we are not creating a NASA program to worry about references and / or names.
We copy the code that you leave above https://pastebin.com/Shgmywrs and save it (it is also optional, I usually do it)
Once done, with Ctrl + Shift + B we compile the project
We should get the following message
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
That says everything went well.
We go to where the projects are saved by default, in my case:
c: \ users \ user \ documents \ visual studio 2013 \ Projects
inside a folder was created with the default name or the one that we add in my case is ConsoleApplication1  we go inside and then to the Debug folder and our DLL  ConsoleApplication1.dll should be We copy and paste it into the system and we are done with this.
Then we go to l2.exe(before we make a copy of the exe) right click, and if they installed the CFF Explorer, Open With CFF Explorer should appear and if not, they go to the program and open it from there.
They go to the Import Adder part then Add and we look for the dll that we create and copy into the system. Once the DLL has been added, the following appears: We

select _DllMain @ 12 >> Import By Name and then Rebuild Import Table . There is no sign saying Import Table correctly rebuilt. and we finish saving the l2.exe with the changes made. Then it is only to open the L2 and within the system "Interface.decrypted.u" will be created
for you. To be able to decrypt other files (ukx or utx) you will have to change something in the code and it is the following

  

appLoadFileToArray(TArray, L"..\\System\\Interface.u", *((int *)GetProcAddress(GetModuleHandleA("Core.dll"), "?GFileManager@@3PAVFFileManager@@A")));
appSaveArrayToFile(TArray, L"..\\System\\Interface.decrypted.u", *((int *)GetProcAddress(GetModuleHandleA("Core.dll"), "?GFileManager@@3PAVFFileManager@@A")));

 

for example, if you want to decrypt a texture, copy the .utx into the system, changing the extension to .u (I think it's not necessary, but never try) and in the code change the following:

  

appLoadFileToArray(TArray, L"..\\System\\Textura_que_quiero_desencryptar.u", *((int *)GetProcAddress(GetModuleHandleA("Core.dll"), "?GFileManager@@3PAVFFileManager@@A")));
[background=#2a2e31]appSaveArrayToFile(TArray, L"..\\System\\Textura_que_quiero_desencryptar.decrypted.u", *((int *)GetProcAddress(GetModuleHandleA("Core.dll"), "?GFileManager@@3PAVFFileManager@@A")));

 

compile the dll again and copy it into the system and voila, open l2 and create the Texture_que_want_desencryptar.decrypted.u then with the umodel you can extract the textures.

 

Decryptor for * u files encrypted by Smart Crypt of early revisions.
By default, for Interface.u, however, using the source below and the C / C ++ compiler,
you can use this method for other files as well.

 

 

  • Place decrypt files in the System folder
  • Place encrypted files in the System folder ( interface.u )
  • Run L2.exe
    Now there are decrypted files in the System folder ( Interface.decrypted.u )

}
bool dumped = false;
void StartCheck()
{
// wait until WinDrv is loaded just so we know everything we need is initialized correctly
if (GetModuleHandleA("WinDrv.dll") != NULL) {
if (!dumped) {

dumped = true;
}
}
}

It's not entirely clear what the files in the archive with a password are for?

 

probably in order to support the forum - buy vip status from maxtor / celestine

and then you will be able to see the password from the author of the topic in this topic.

      Skins for H5

      By NoJobRob · Posted

      You can find some H5 skins shared in old L2 modding Discords, but most of the higher‑quality ones are either paid or come bundled with full client edits. I usually mix in commissioned work and whatever I can patch myself. On a side note, I fund a lot of these commissions by selling off game items through instant sell cs2 skins, which has been a quick way for me to get some cash for projects.

      There is no need for gRPC in this case, even tho originally it was gRPC based but since we don't need it to be bi-directional, we switched to simple http requests for the web calls and SSEs for the data streamed from the server. There are distributed locks in place to precent race conditions between actions that can happen between multiple web instances and the server.   Local models can also be slow depending on the model, and most external models can actually be faster than local ones if you use Flash 2.5 or something along those lines. I am running on 512GB of Unified Memory on my Mac Studio M3 Ultra so the speed of the local model for a small model is pretty good but I tested it with Gemini too and it works equally as fast and in some cases faster. The way it works is that I'm using pgvector (one of the benefits of moving to Postgres) to search the data and see what the player can see etc and there is some batching of the next few actions for 2-4 seconds for the user until the next LLM request fires. The batching also includes branching on logic so if they for example fall under some HP they will move to kiting instead of attacking or maybe they heal etc.   Everything is authed and permission-based. The server and the backend of the frontend have secure communication between them, either with a symmetric key (not recommended for production) or a certificate (the recommended way), so there is no worry. It's all tied to the account's access level, etc., so nobody can make an action that they normally wouldn't be allowed to do. Even the MCP is token-based, and there are prompt injection protections in place. The MCP is audited, and every mutation needs confirmation. The admin area is only accessible to the admin account anyway so normal users can't access it.
