How can each free VPN config file be a different SHA 256 hash?
1. I downloaded this free VanwaTech-Free-OpenVPN.ovpn config file.
https://vanwa.tech/download-free-openvpn-config
2. I ran a SHA 256 hash on that file.
3. Seconds later I downloaded the file again.
4. But it has a different hash (otherwise it looks the same).
How can that be?
Why?

Yes, they are different files. Their **"shadows" don't match.

If you have DOS, do a FC (file compare).
If Linux, a diff.

Trackers. Unique_ID.

It's "free" for a reason.

**"shadow" is the word of the day. And yesterday. I have Shit

The site generates a new key and certificate for each configuration

requested. This is to make middlemen attack more difficult, because the
encryption key is not fixed. IOTW, the longer a VPN configuration is used,
the higher the chances middlemen attacks will succeed.
