How to set Net Core application or some data inside as non swappable?

Question

I need to store some secure files only in memory without saving on HDD. If I have files as simple byte array it could be saved in pagefile.sys on Windows or swap in Linux.

Even if I encrypt data in memory, that still can get on the hard drive. I don't need security in memory, but I have to be sure that when I turn off my server, nothing is saved on it.

Are there any tools to do this quickly and easily?

Answer 1

There is no way to avoid swapping out programmatically. You can only disable swapping on OS-level, but that will have unpredictable effects.
