Can anyone recognize this coding?

Can anyone recognize this coding?
Or is it encrypted with some program? If anyone knows, please help in deciphering OTC files

its encrypted to protect the lua files from thiefs like you make your own.

So the cipher knows only who encrypted it? Well, that is nothing we can do. I just wanted to know how I can make my own client for classictibia.com. Namely, when I enter all the data, I do not want to display the character list. Stops on the window connecting to the server.

ok technically if there is modules that are vanilla ( 1:1 otc and are encrypted) you can pretty much compare it and find encryption key within seconds and then decrypt all of the files but thats all you gonna hear from me.

I will not play with it This server also uses a regular client converted to version 772. But I can not connect using the standard OTClient. Maybe you know what I need to have to connect via standard OTClient?

1 check with ollydbg the Pushes

Change tibia client version [7.72]

Requirements: Tibia Client 7.72 OllyDBG Decimal to Hexadecimal Converter 1.- Open OllyDbg -> File -> Open -> search Tibia.exe: press ALT + E and we will open a window Executable Modules, that window will cliick to Tibia.exe as is shown in the following image: In the next window right...

otland.net

and make OTC report as exact same version the other thing is something like this might give you idea when i try to connect with classic tibia client to my server:
