FHE is interesting: https://en.m.wikipedia.org/wiki/Homomorphic_encryption

Sure, but how does it help in this specific scenario?

Can't you just run the program inside a VM of some sort and encrypt the whole image that way? I guess during runtime the contents in RAM won't be encrypted, but when the image gets saved back to disk, it should be. e.g. in Parallels, they have built-in AES-based password VM encryption: https://kb.parallels.com/8832 Or in VirtualBox: https://docs.oracle.com/en/virtualization/virtualbox/6.0/adm...

I think a sandbox should be sufficient.

Is there readily available software for that?

The building blocks are there AFAICT, but I’m not sure I would say they’re neatly productized.
