Understanding VRChat Cache Encryption
-
What's the chances they change the encryption scheme once a noob friendly tool is available. And honestly how much farther can they go to try and secure the files.(I can think of a few ways) If EAC is anything like the other anticheats out there once a hash for a tool is identified it can just refuse to run while that known exe is in the process list. The way we got around that with VAC back in the day was loading another processes suspended, carving it out with RunPE. Then connecting to a randomised port that acted as a serial on another device to hook and read remotely.

You're exactly right about the caching behavior when EAC is disabled. That's precisely why this "base version" I'm releasing at 50 upvotes will only work for avatars you own or the public official ones. It strictly requires VRChat to be launched with EAC disabled.As for your method, hooking CreateCached_Injected to null the key is a classic way to stop the encryption from happening. But my tool takes a different route. Instead of preventing the cache encryption from the start, I hook directly into... well, let's just say I dynamically dump the live keys straight from memory as the game naturally decrypts the blocks.
I'm still holding onto the advanced version that safely extracts keys while the game is running normally with EAC fully loaded. I want to see the feedback on the base version first before deciding if I'll ever release the full bypass.
Let's hit that 50 upvotes goal first and I'll drop the base version

can you release the version with bypass and make it paid

I honestly don't really want to deal with setting up a login system or anti-crack protections. My current idea is to either just release it completely for free, or maybe set a donation goal and drop it once that's met.Plus, everyone here on Ripper shares everything anyway. Rather than waiting for someone else to inevitably leak it, I figure it's probably better to just release it myself directly. But anyway, I'll wait and see the feedback first. Who knows, if I just drop the base version, someone else might pick it up, improve on the rest, and share it anyway

can some one rip these avatar's for me? https://vrchat.com/home/avatar/avtr_723045f0-c464-4f06-be83-8b20052a27ef https://vrchat.com/home/avatar/avtr_88236f61-fcd8-42ee-8e14-2462a602dd73 https://vrchat.com/home/avatar/avtr_fd3ed848-0268-40ad-b92f-22470498485b i would love if some one could

@pendatron thank you for the explanation. How does one inject / hook to VRC without setting off EAC? I've been reluctant to do anything related to messing with the process itself.
-
interesting way of getting something patched, might as well just tell the vrchat developers how you bypass encryption
-
Only a few upvotes left before the public drop. Here's a little teaser for the ones waiting: https://streamable.com/37nx1q I might drop the full Source Code or the EAC Fully-Loaded bypass later. Still deciding how many upvotes those two are worth. Also, is dropping a donation link against the rules here?

I mean, I could try to buy the full version. Maybe.

bump, i would like the full version, since i wnna grab models the og creators stop their downloads years ago and my friend's drive got corrupted

I'm not going to teach you how to use it, good luck with that.
Next: 150 upvotes for the full source code and a study guide on how it works under the hood
@daswdas I have been trying to use asset ripper it just doesn't work. I have read your big post about ripping avatars. I think a lot people just don't know how to help someone on here. Should I ask you like a 100 questions to figure out what you need help with. It's challenging enough to learn unity and blender. I think people on here should say how you can help instead of complaining about no one doing it. I'm trying to find some ripper software that actually works so I can upload this avatar to one person on this website and for me to have the files to make this avatar so much better than it is.
