For the usual reasons we want to cache certain resources browser side, e.g. list of products bought in the past.
This list is confidential in my case, and I want to mitigate the case where an attacker get physical access to the (os password locked) machine or to the hard drive.
Are there standard strategies/JS libs/browser support for such scenarios? It seems browsers in general will cache files in an unprotected way (not encrypted essentially).
