# WireGuard Cryptographic VPN Tunnels

Configures WireGuard VPN interfaces (wg0): Curve25519 public/private keypairs, AllowedIPs routing, persistent keepalives through NATs, and kernel-space WireGuard network security.

## When to Invoke
Invoke this skill whenever you need to:
- setup wireguard vpn
- generate wireguard keypair
- configure wg0.conf

## Execution SOP & Rules
1. Generate keypairs with wg genkey | tee privatekey | wg pubkey > publickey.
2. Configure /etc/wireguard/wg0.conf with [Interface] and [Peer] blocks.
3. Set PersistentKeepalive = 25 on peers behind NAT routers to maintain connection state.
4. Enable and start the tunnel using systemctl enable --now wg-quick@wg0.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
