关于包的加密，在 Project Settings-Crypto 中有四个选项：

  • bEnablePakIndexEncryption: 加密 Pakindex
  • bEnablePakIniEncryption：加密 pak 中的 ini
  • bEnablePakUAssetEncryption：加密 pak 中的 uasset
  • bEnablePakFullAssetEncryption：加密 Pak 中所有的文件

但是除了 bEnablePakIndexEncryption 之外，其他的参数并不是传递给 UnrealPak 的命令行参数，而是生成的 Paklist 中每个文件的参数：

对 paklist 中的对应格式文件添加 -encrypt 参数。

"C:\Users\lipengzha\Documents\UnrealProjects\Blank425\Intermediate\Staging\Blank425.upluginmanifest" "../../../Blank425/Plugins/Blank425.upluginmanifest" -encrypt

当开启了 bEnablePakIniEncryption，就会对当前 Paklist 中的 ini 文件添加-encrypt 参数。
