Loosely translated: The Every Government from A-Z is spying on you.
Oh, dear. Translated as best I can: a VPN (Virtual Private Network) is a system wherein the user "tunnels" through using encryption that is based on a random number generator (in this case), which, if not random or otherwise compromised, allows realtime decryption by a third party who is capturing the packets.
Dang, that isn't much better. Sorry.
I do NOT trust the hardware RNG that many processor types have built in.
Just too tempting for government to bribe or threaten hardware manufacturers into weakening.
I build my own RNG using something like diode noise as a source.
