thats my friends personal model and there not giving that one out

If anyone can find the VRCA or original model of https://vrchat.com/home/avatar/avtr_e3f4aa12-2144-4d4d-b56c-c8f8507aa680 I'll be incredibly grateful, since the original is lost media to my knowledge.

Is there any lurkers here willing to get some VRCAs for me w/o me needing to add them on discord through this sites message function or something? if so DM me
-
I'd like a few worlds ripped if ripping worlds is still possible. Tried the old way of getting it via cache, no dice

@agent287 I just need like 3, I really don't feel like getting my discord logged. If anyone's willing to offer here that'd be dope.

I been wondering that too. Even if some methods are being kept hidden, has decrypting become possible or is everyone just doing the "rip before decryption"?
-
@Alisan People are hiding behind paid for services.

I was able to get unencrypted vrcw files but only through a very buggy method (no avatar loading(I wish brother)). This confirms at least for me that NO SERVER SIDE ENCRYPTION is happening.
@Daito1234 what buggy method?
-
Still waiting for answers about the buggy method. Also, encrypted files do nothing but cause problems in VRChat.

Adding this in a second comment but just an observation. When you start up VRChat.exe and you try to load the Public avatars it still fetches them online. It still creates a __data file in your cache folder, yet the unencrypt vrca's for them are in C:\Program Files (x86)\Steam\steamapps\common\VRChat\VRChat_Data\StreamingAssets\Avatars
This has been there before the encryption update. I thought they were there cause the game devs just wanted people to have models that they can use when theyre testing out stuff in the game running it directly from the exe.
Yet it still makes server requests to download them and encrypt them when theyre unencrypted and just sitting their on your PC? The game also does not use PhotonEncryptorPlugin.dll running from the exe, looking at procmon, but only calls GameAssembly.dll
Just kinda weird idk, why download the files from a server if theyre already on your PC? Why still encrypt them?

@Linze i don't think so, just off a glance it doesn't import any crypto libraries. after some further investigation its definitely just for encoding media stuff.
i have a full dma set up and i could get started poking around the game to try to find something useful, but i figured id look around here first. i mean if i can just grab vrca's from memory that would be pretty sick. it seems like most of the stuff from gameassembly is encrypted but i have found a few things like the avatarmanager and the player objects, im just not sure what to make of it all. if anyone has any advice of what to be looking for that would be great.

here my research i been doing so far
so every unencrypted file of vrca or vrcw they contain unityFS version like this
UnityFS 5.x.x 2022.3.22f1
while encrypted or game contains
UnityFS 5.x.x 2022.3.22f1-DWR
i do not know what DWR for but it could be a clue, every unencrypted today contain like BuildPlayer-(world name here).sharedAssets and for avatar file they contain CAB-(number letters here), which readable in assetripper
while encrypted has none and has bunch of @@@@@@@@@@ spam at the end of every vrca-vrcw file, i look dll files, inspecting any clue i found they use AES-CBC-GCM-SHA256 kind of encryption in game dll, try to look into game data so far i only been looking into the GameAssembly.dll and PhotonEncryptorPlugin.dll and other dll i may forgot when looking into thempost mentions of game encrypt in unity
https://discussions.unity.com/t/how-would-you-secure-an-encryption-key-in-the-client/640245/36document of encryption
https://docs.unity3d.com/Packages/[email protected]/manual/encrypt-a-model.htmlidea i have are either the assets being streamed in something in our machine or they are stored somewhere as .sharedAssets, i am not sure if this will help someone in the future of getting unencrypted file including private avatar, hope it helps
I'm bad at understanding english word
I fix .vrca/.vrcw stuff for free and for fun! Depending on file, every outcome and vary might be different than the original avatar has due to the toggles and much more, send me a pm if you need an avi that need to fix or cracking a password locked avatar or send me .vrca file or through my pms and i will extract/fix them for you!
request is semi-open, only on unencrypted __data file aka .vrca or .vrcw
