How does a VPN work?
A VPN creates an encrypted tunnel between your device and a server, and routes your internet traffic through it. Your data travels inside that tunnel, so it can’t be read or traced back to you on the way. Here’s what actually happens under the hood — explained clearly, without the jargon.
Step 1 — the encrypted tunnel
When you connect, your device and the VPN server perform a handshake and agree on secret encryption keys. From that moment, everything leaving your device is encrypted with AES-256 before it hits the network, and is only decrypted at the server. To anyone in between, it’s meaningless noise.
Step 2 — routing through the server
Your encrypted traffic reaches the VPN server, which decrypts it and forwards it to its destination on the internet. Replies come back to the server, get encrypted, and travel back through the tunnel to you.
Step 3 — IP masking
Because your traffic exits from the VPN server, websites and services see the server’s IP address instead of yours. That masks your identity and approximate location, and breaks the link between your activity and your real connection.
Protocols — how the tunnel is built
The protocol is the rulebook for the tunnel. Each has trade-offs, and VPNTYPE supports them all so you can pick the right tool:
- WireGuard — modern, very fast and lean; the default for most users
- OpenVPN — battle-tested and highly compatible
- Shadowsocks, VLESS, VMESS, V2RAY, XRAY — obfuscated, for restrictive networks
Why AES-256
AES-256 is a symmetric cipher trusted by governments and banks worldwide. Brute-forcing it is computationally infeasible with current technology — which is why “military-grade” is more than marketing here.
Frequently asked questions
What is the safest protocol?
WireGuard and OpenVPN are both strong. WireGuard is faster and leaner for most users; OpenVPN and obfuscated protocols help on restrictive networks.
Is AES-256 secure?
Yes — it’s the encryption standard used by governments and banks worldwide and is considered infeasible to brute-force.
Does the VPN see my traffic?
Traffic is decrypted at the server to reach the internet, which is why a strict no-logs policy matters — VPNTYPE doesn’t record it.
What happens if the connection drops?
With a kill switch enabled, all traffic is blocked until the tunnel is back, so nothing leaks outside it.
