Wintrust DLL when building from source (lemmy.ml)

Hello, I've built GenP from source and was able to obtain the dependencies (UPX, AutoIt) from official sources for security reasons. The wintrust DLL is a dependency I could not obtain myself.

The file needs to be unmodified and original. I've googled the hashes (wintrust.dll - 1b3bf770d4f59ca883391321a21923ae) and could not find mentions of this version. My Windows 11 installation comes with its own version (in System32) but the file size is quite different and it's obviously a much newer version.

Thanks!

As an additional data point, I’ve also verified this by patching a current Windows 11 wintrust.dll (v10.0.26100.7705 - 531KB) using the same script that was originally tested against the provided wintrust.dll (v10.0.19041.630 - 374KB).

In this case, the patch applied cleanly, the expected byte changes were made, and behaviour was consistent.

This confirms that using a wintrust.dll from a legitimate Windows installation generally works in practice even when versions differ, while the provided DLL remains the known and tested baseline.
