Public Key

Whenever the client gets a request like studio.ashx or connects to a server, that request or connection utilizes the already patched public key inside the client binary.

Tutorial

To patch the public key, follow these steps (a modern one for rbxsig2 and above + mobile will be made later)

• Download RBXSigTools
• Open RBXSigTools, that'll generate PublicKey.pem, PublicKeyBlob.txt and PrivateKeyBlob.txt and note that the private key should never be given out as that'll be used by the server to sign studio.ashx and join.ashx
• Open HxD
• Drag or open up your RobloxPlayerBeta.exe (or RobloxApp.exe) binary
• Hit CTRL+F on your keyboard
• In the text box put in bgiaa and click OK
• Select the entirety of the public key (until you reach the dots) and paste in your new one
• Save the patched binary via clicking CTRL+S
