Block URLs and encrypt hosts file

Question

I am looking to block a few URLs from an android device... however, I would like to take an extra level of security and password protect the hosts file.



I think I can do that with ES File Explorer by the looks of it?

I'm wondering, if I encrypt the hosts file but then uninstall ES File Explorer, will the hosts file stay encrypted?



Or if not, is there another way to achieve this?

Answer

If you encrypt the hosts file, the system won't be able to read the file, so it won't work any more. But there's no need: since you need root access to edit the hosts file anyway, any app that you don't grant root access won't be able to edit the file.
