Easy to follow tutorial for encrypting your PCK file

pablo_adf · April 20, 2025, 9:48pm

So I’ve been trying this with 4.3 and I’ve run into several issues:

ld.lld: error: duplicate symbol: PKEY_Device_FriendlyName wwhich is solved by renaming the variable
When exporting the template its as if the set key either in cmd or powershell isn’t read so then the game can’t unencrypt at runtime.

Is there any similar guide? Seems this one is not working for newer builds.

The first issue was a bug in the code, which has been fixed, see:

github.com/godotengine/godot

Unable to build Windows release template (ld.lld: error: duplicate symbol: PKEY_Device_FriendlyName)

As for the second one, I’m not sure what happened, but the guide works even to this day with the newest version of godot, as I’ve had to do it a few days ago.
You need to set the key before you build the release template, then you need to put that same key in Godot’s export window, and making sure you use the template you built, not the official ones.
