I have been looking into vpn (virtual private network). And I wanted to know more about the theory, how does it work really:
- what does it do with the packages?
- why is it secure? (or why can it be unsecure)
- how does it work on the internet?
- how can it simulate you're coming from another country?
It feels so mainstream nowadays (sole available directly from the browser), that I wanted to understand better what happens when you use one.
