CryptBaseBypass

The project creates a dynamic linked library that proxies the original CryptBase.dll and manually loads the BCrypt.dll. After that the original BCryptVerifySignature method can be hooked, allowing us to bypass the check.

Having the proxy CryptBase.dll in the root directory is often enough for using the bypass (e.g. for Frostbite games).

Build in Debug mode to enable a console window for more verbose logs for whats currently happening.

The default output folder is called Artifacts.

MinHook

The library MinHook is used for hooking the function.
