## What it is
DSVPN is a dead-simple, single-binary VPN tool written in C that tunnels traffic over TCP with modern, formally verified cryptography. It requires no configuration files or firewall rules—just a shared key and one command on the server and client.

## Use cases
- set up a simple personal vpn server
- secure traffic on untrusted public wifi
- bypass restrictive networks that only allow tcp 443
- create a point-to-point encrypted tunnel between two machines
- replace openvpn/wireguard with a minimal zero-config vpn
- prevent ipv6 leaks when connected to a vpn

## When to choose
- you want a minimal, zero-configuration vpn with a tiny code base
- you need to tunnel through networks where only TCP/443 is open
- you prefer no external dependencies and constant memory usage
- you run Linux, macOS, or a BSD and are comfortable with the command line

## When to avoid
- you need UDP-based performance like WireGuard for high-throughput use
- you need multi-client user management, GUI clients, or mobile apps
- you need advanced features like split tunneling or centralized key management
- you need Windows support
