Mount encrypted pak file at runtime

I have created an encrypted pak file using unrealpak.exe
I am able to extract the contents using the key with unrealpak.

In my game I load content needed from a pak file on the fly, and all seems to be working well with unencrypted paks.

But I am not able to get the encrypted pak file to mount in the game at runtime. I can’t seem to figure out where it wants me to supply the aes key.

it crashes on the PakFile declaration line everytime, complaining of an invalid key

FPakFile PakFile(&PlatformFile, *PakFilename, false);

Can anyone show me where to supply the needed key to mount the pak file?

i tried added keys in various ini files. no go.
i tried added the public definition of AES_KEY in my projects build.cs file. nothing.
i tried the new crypto plugin, and added the key in project settings, no luck.
then i used a generated key from project settings to pak file, still won’t mount.
i looked into these IPlatformCrypto classes but could not seem to get an understanding enough to use them correctly or at all.
any thoughts out there would be much appreciated, thanks!

today I tried using the command line parameter of the FPakPlatformFile->Initialize method… I am not getting anywhere with this problem. I must be doing this very wrong.

for pak files not encrypted I was able to load with the following code:

    IPlatformFile& PlatformFile = FPlatformFileManager::Get().GetPlatformFile();
FPakPlatformFile* PakPlatformFile = new FPakPlatformFile();
PakPlatformFile->Initialize(&PlatformFile, TEXT(""));
const FString PakFilename = "F:/test48.pak";
FPakFile PakFile(&PlatformFile, *PakFilename, false);
const FString MountPoint(FPaths::EngineContentDir());
if (PakPlatformFile->Mount(*PakFilename, 0, *MountPoint)){...}

Has anyone encrypted a pak file and mounted it at runtime?

moved to packaging and deployment in hopes of catching the eye of someone in the know :slight_smile:

moved to c++ for the real experts !
any thoughts would be most appreciated.
