NAME

rp — high-level interface to rosenpass

SYNOPSIS

`rp`	[`explain`] [`verbose`] `genkey` `...` \| `pubkey ...` \| `exchange ...`

`rp`	[...] `genkey PRIVATE_KEYS_DIR`

`rp`	[...] `pubkey` `PRIVATE_KEYS_DIR` `PUBLIC_KEYS_DIR`

`rp`	[...] `exchange` `PRIVATE_KEYS_DIR` [dev <device>] [listen <ip>:<port>] [peer PUBLIC_KEYS_DIR [endpoint <ip>:<port>] [persistent-keepalive <interval>] [allowed-ips <ip1>/<cidr1>[,<ip2>/<cidr2>] ...]] ...

DESCRIPTION

The rp program is used to build a VPN with WireGuard and Rosenpass.

The optional [explain] and [verbose] options can be used to obtain further help or to enable a detailed view on the operations, respectively.

COMMANDS

genkey PRIVATE_KEYS_DIR: Creates a new directory with appropriate permissions and generates all the necessary private keys required for a peer to participate in a rosenpass connection.
pubkey PRIVATE_KEYS_DIR PUBLIC_KEYS_DIR: Creates a fresh directory at PUBLIC_KEYS_DIR, which contains the extracted public keys from the private keys generated by genkey and located inside PRIVATE_KEYS_DIR.
exchange PRIVATE_KEYS_DIR [dev <device>] [listen <ip>:<port>] [PEERS]: Starts the VPN on interface device, listening on the provided IP and port combination, allowing connections from PEERS.

EXIT STATUS

The rp utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

In this example, we will assume that the server has an interface bound to 192.168.0.1, that accepts incoming connections on port 9999/UDP for Rosenpass and port 10000/UDP for WireGuard.

To create a VPN connection, start by generating secret keys on both hosts.

rp genkey server.rosenpass-secret
rp genkey client.rosenpass-secret

Extract the public keys:

rp pubkey server.rosenpass-secret server.rosenpass-public
rp pubkey client.rosenpass-secret client.rosenpass-public

Copy the "-public" directories to the other peers and then start the VPN. On the server:

sudo rp exchange server.rosenpass-secret dev rosenpass0 listen 192.168.0.1:9999 \
    peer client.rosenpass-public allowed-ips fe80::/64

On the client:

sudo rp exchange client.rosenpass-secret dev rosenpass 0 \
    peer server.rosenpass-public endpoint 192.168.0.1:9999 allowed-ips fe80::/64

Assign IP addresses:

sudo ip a add fe80::1/64 dev rosenpass0 # Server
sudo ip a add fe80::2/64 dev rosenpass0 # Client

Test the connection by pinging the server on the client machine:

ping fe80::1%rosenpass0 # Client

You can watch how rosenpass replaces the WireGuard PSK with the following:

watch -n 0.2 'wg show all; wg show all preshared-keys'
