Hello,
I am going to build an app that will store secured data. It cannot be just a data on cloud but it should be, first, encrypted and secondly, not easily accessible.
I was thinking about using a high level encryption for a data stored on a separated server. But the problem is that if it is accessible easily from the app it will be useless.
I am thinking about using a usb as a "key". Something like that is also used in crypto wallet I think.
Is it possible to use a usb key ? If yes how will it work ? The connection between the client and the server should also be secured (maybe it is the case already).
Do you have any other better ideas ?
I am thinking about using supabase but why not firebase. Local storage could also be a solution.
