idb-cache: IndexedDB-based encrypted caching library; can be used for TanStack Query persister storage

[aaronshaf]

Unencrypted IndexedDB file storage has a few problems. From a 2014 paper:

"While the browser can delete IndexedDB files stored on the local filesystem, they can be retrieved by Encase. Unfortunately, the retrieved data is in an unencrypted format, and given the nature of the data held within the IndexedDB API, a potential security issue exists."
— Stefan Kimak, Jeremy Ellman, Christopher Laing, "Some Potential Issues with the Security of HTML5 IndexedDB", IET Systems Safety and Cybersecurity Conference 2014.

It is also an issue in the scenario of multiple people sharing the same device and browser.

idb-cache is an IndexedDB-based caching library with encryption and chunked storage, designed for performance and security.

It implements the AsyncStorage interface. Hence, it can be used for TanStack Query persister storage.

I am still kicking the tires. But I'd love your feedback.
