VRChat added VRCA (?maybe VRCW too) protection

[avatarofcorn]

It's added for VRCW as well. I heard about it and went on the mad scramble to back up memorable worlds from the early days and they're all scrambled. I have a feeling they only did this so people can't "port" user-made worlds to other social VR platforms since VRChat has gone down the shitter. They don't care one bit about their users and their concerns with "avatar ripping".

If there is a will there is always a way please don't lose hope

[trejectt]

Vrchat now uses AES-GCM encryption. The only way to get any type of unencrypted vrca or vrcw is with a modded client. Otherwise dump the game and get the decryption method. And boom. But the method is lazy and there are ways around this. Cannot say more right now.

[Reym]

@trejectt dumping the game and get the encryption?, that actually could work, problem is gonna take very long to locate where the encryption are, and if it an encryption we need a key

[sas909]

@trejectt Why are you so sure it's AES encryption?

[chocolate]

I usually used loadbundle, and I was hoping that at least this would become usable. But if encryption measures have been implemented, there’s almost no chance it will work in the future.

@trejectt Yep, saw one video where client user was able to extract avtr file w/o encryption. And from other source I found out that it is indeed client-sided. Files on VRC servers are still un-encrypted, and encrypted locally. So if anyone have a backup of previous VRC client version, they can still load and rip. Or wait for someone to decompile VRC and make another tool...

@avatarofcorn I heard personally they did it because they've started a partnership with Booth, but unsure how true that really is. At least the community had time, but I fear vrchat is certainly gonna turn into Pokechat for vrca's.

[trejectt]

@Real-Visitor I havent found a version that lets you play. i have all the way back to last year. all force to update

[chocolate]

I downgraded VRChat, but I can’t launch it because a warning message says, "Please update."

[NonckUnck]

@chocolate yeah it only worked for a few hrs into the next day.(28th) i helped someone figured it out

[Reym]

@Real-Visitor what if the connection download is intercepted? what would happen?

[DrKWolf]

Can someone help me on DM for getting an avatar? i still have the ID of it.
extracting vrca from cache doesn't work anymore, and assetripper can't load assets folder and shows unity version as 0.0.0a0

@Hardware98 It was clear as day what the outcome would have been when EAC was rammed down everyone's throats to the protest of nearly forty thousand downvotes on the Canny. Didn't take long for them to charge for what mods and other social VR platforms do for free. Notice how development time now is spent on monetization, instead of fixing bugs and improving the existing system. I suppose the massive layoffs last year were to remove staff members who gave half a damn about the community. The rest aren't talking but you can figure it out from how angry Merlin got. (For those who don't recognize this name, he's the guy who brought us UdonSharp and was hired to overhaul the broken Udon system when he was suddenly fired.)

@Reym Try setting up a transparent MITM proxy with a self-signed TLS cert. Your mileage might vary, given the ring-0 rootkit on the machine.

[Reym]

@avatarofcorn ring-0?

["'Real' Visitor"]

@Reym Client users can still take pure VRCA files, due to them not being encrypted server side

[gameboydsps]

I know nothing, but I have noticed that while the Avatar is in use a __lock file is created in that path. I cannot do anything with this file, but when unloaded it disappears.

[Greg77]

So once the file on the cache is encrypted there is no way to revert it?

[Linze]

@Real-Visitor Is that possible to intercept pure vrca and transmit it to another folder after it has been downloaded instantly?

[Linze]

@Real-Visitor Do oculus ver or non steam version have same encryption?
