Minecraft Marketplace Contents Decryptor

I cracked the DRM used by the Minecraft Marketplace, and wrote a tool to decrypt & crack any premium worlds, skins, resource pack or persona contents in C#

Here is my source code to this tool:

"Version2" entitlements

Hello~ it seems as of 1.19, mojang changed the entitlement files that your contain pack's Content Keys

they added some extra encryption to it

the Entitlement Files now contain the header "Version2" and then a base64 string, decoding that string is an encrypted version of what was there in 1.18, and also what is there if you connected directly to the API and requested your inventory.

The encryption works as follows

1- locate the options.txt file; usually its at
%LOCALAPPDATA%/packages/Microsoft.MinecraftUWP_8wekyb3d8bbwe/LocalState/games/com.mojang/minecraftpe/options.txt

read the "last_title_account_id" for example; 1D05A92F556ACCD5
append last_title_account_id to itself, resulting in 1D05A92F556ACCD51D05A92F556ACCD5
then XOR that with the constant "X(nG*ejm&E8)m+8c;-SkLTjF)*QdN6_Y"

the result of that XOR is the aes-128-cfb key required to decrypt the entitlement buffer, then you just read it the same way as before

which i dont think i actually explained earlier, if you want more details,
read the code

here is an updated verison to do all the new stuff they added:

Version 2 encryption

Hello,

Is it normal that their encryption is that way that bad?

I successfully unciphered content with an old version and your message tips. But recursive path direction no longer work. I had to pass path manually.

J'attends que mon compte soit validé pour pouvoir essayer Mc tool, j'ai acheté un pack sur le marketplace avec un overworld cubemap à l'interieur qui m'intéresse vraiment, un des plus réaliste à ce jour pour la version Bedrock de Minecraft ! J'ai hâte de pouvoir le décrypter et pouvoir l'intégrer à mon pack personnel
