Re: Genshin Impact Full release .blk Encryption

Post by yummmy »

I have a decent bit of experience bypassing hardware implemented encryption keys, but I have a lot to learn on the software front.

Definitely interested in decrypting GE client, and I can help create a clientside "server" for UDP handling.

If anyone can point me in the right direction to get a foothold on the XOR decryption, that would be great.

I am concerned that mihoyo might patch the game in a way that prevents future content updates from being accessible to an offline client (especially if this gets a significant amount of traction), but I guess we worry about that once we get there.

It says it right there "please make sure that the asset_index and blocks folders are in the same directory"

You need a file called asset_Index and it needs to be in the same folder that your blocks folder is in. Do not put it in the blocks folder

I think no emulator support for genshin cause 64bit requirement, even if it said 64bit version of nox,bluestack etc, cause native bridge(libhoudini) to emulate 64bit games already old and not compatible

People have already made some basic mods for the game, texture changes and such, just last night literally everyone on that mod circle got banned for 3 days, seems like miHoYo is aware of the current solution to soft modify the game, maybe in a near future they will find a better way.

Anyways I keep cheering you all to decrypt the current release files, I am hoping to get some new textures and models, got to the point where the characters I am looking for are not in the CBT2 files and it seems like I am gonna have to wait :cry:

I have unreleased character models from CBT 2 Like Ayaka, Yaoyao, Zhongli, and more unreleased characters in obj.
Do you mind if i join the discord server? we could find the xor key if we can bypass the anti cheat program they implement.

Hello, have you tried checking/loading the "blocks_export" folder in Asset Studio?

For all those interested in the discord, we are just looking at people with advanced (and I mean serious) skills in reverse engineering and decrypting right now.
Just dont want to attract too much attention with this as of now..
So please PM me if you think you can help, we are hitting some serious walls.

Dont worry, we'll let all of you know when we get a breakthrough !
