Creating and Accessing Encoded, User-facing Containers?

[aaronventure]

I want to allow the user to create their own content with a predefined scheme, and then export the collection of it into a single file which can then be easily distributed and another user can simply point to it and load the content.

The content would be a any combination of

• limited amount of audio samples (probably less than 300 in total)
• arbitrary data files that can be read using the filesystem API
• images

Theoretically this is already possible using ZIP, but I'd like the data to stay in one file on the user's computer and allow the user to provide an encryption key to prevent it being unzipped.

This means that HISE would have to access it using a sort of private key, if the file is encoded using a public key.

How would this play with the audio files? If samplemaps cannot exactly be exported, there'd obviously be a metadata file that would help the plugin recreate the sample map upon loading the file itself.

I'm aware that the expansion system might offer these things, but from what I gather, it can only be created from within HISE, not from an exported plugin i.e. using the API. Is this correct?
