Does anyone have knowledge how to deobfuscate these game files? Or maybe even create programs for the purpose of extracting "coded" archives? The reason why I ask is because, lately ive been playing this game "Don't Starve Together", and they have locked a lot of content out from from offline lan gameplay. I cant play that much online due to limited broadband, and I can't mod it in either due to they having their own encryption on some of their files.

The files are ".dyn" and its their own created "archive" extension. I heard ONE guy at the forum bragged how easy he cracked this and made a simple C program in 60 minutes to deobfuscate the archive (a .dyn file decompiler). He is the only one who have created such a tool. However he refuses to share this program, which is all in his right of course since he made it.

No one else have been able to do this, but I ask, how can it be done? Where can I ask, if you can't answer in this subreddit? And most of all could anyone please do it for me and send?

This is ONE of the files from the game: https://www.mediafire.com/file/8b9eqdpes6gr32s/wortox.dyn/file
