# cvpn
A simple vpn written in C
[](https://forthebadge.com)
# Features:
- this is a cli vpn like openvpn
- Runs on TCP. Works pretty much everywhere, including on public WiFi where only TCP/443 is open or reliable.
- Uses only modern cryptography, with formally verified implementations.
- Small and constant memory footprint. Doesn't perform any heap memory allocations.
- Small (~25 KB), with an equally small and readable code base. No external dependencies.
- Works on Linux, macOS
- Doesn't leak between reconnects if the network doesn't change. Blocks IPv6 on the client to prevent IPv6 leaks.
