How to create a protected file

6 views (last 30 days)
I'm currently building a log in app in appdesigner and i need to manage users and passwords within the app, I already found a way to hash the passwords , I just want to know if is there some way to create a file where the hashes are stored in a secure form? like a read only file or a protected file that can not be modified.
I would appreciate your help and thanks in advance.

Not really.
You can embed a SoC kind of computer within a tamper-resistant covering that would be likely to break with all of the common methods of removing the covering. You know the kind, ultra hard resin infused with metal flakes designed to scatter x-rays and ruin MRI. I really don't know the current technologies.
