KeywordDescription
no(Optional) Removes the peer public key from the VPN.
idThe VPN identifier. Must be a number in the range 0-1022 or the keyword "auto".
keyThe peer's public key
## 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. ## Examples ``` vpn peer auto public-key 7cNt7EEQVVWVWh+63xY5+dU7uDGZk2IRKENcchJPuS0= ``` ## Related Commands --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.islandrouter.com/island-router-cli-2.3.2/commands/vpn-peer/vpn-peer-public-key.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
