## Defaults

None; a peer's public key must be defined before communcations can take place.

## Usage Guidelines

Each end of a WireGuard VPN has a public/private key pair. The private key is known only to that end, while the public key is shared with the VPN's peer(s).

This command provides Island with a VPN peer's public key.

If a VPN exists with the specified identifier, the existing VPN will be modified; otherwise, a new VPN with the specified identifier will be created. If "auto" is specified for the identifier, a new VPN will be created using the next available identifier.
