I’m working on an Android project in Unreal Engine and want to make sure my Pak files are encrypted before shipping. I’ve already enabled the following settings in Project Settings → Packaging:

Use Pak File

Encrypt Pak Index

Encrypt UAsset Files

Encrypt Ini Files
I’m using the Pak Creator Plugin to generate custom Pak files from selected folders. However, I don’t see any option within the plugin to apply encryption. So I’m wondering:

Does the Pak Creator Plugin automatically use the project’s encryption settings?

If not, is it possible to manually re-encrypt Paks created by the plugin using UnrealPak.exe?

What’s the proper workflow to make sure these custom Paks are securely encrypted and can still be mounted at runtime?

Any guidance or best practices would be greatly appreciated. Thanks in advance!
