Module @libp2p/pnet

Example

import { createLibp2p } from 'libp2p'
import { preSharedKey, generateKey } from '@libp2p/pnet'

// Create a Uint8Array and write the swarm key to it
const swarmKey = new Uint8Array(95)
generateKey(swarmKey)

const node = await createLibp2p({
  // ...other options
  connectionProtector: preSharedKey({
    psk: swarmKey
  })
})
Copy

Private Shared Keys

Private Shared Keys are expected to be in the following format:

PSK Generation

A utility method has been created to generate a key for your private network. You can use one of the methods below to generate your key.

From a module using libp2p

If you have a module locally that depends on libp2p, you can run the following from that project, assuming the node_modules are installed.

node -e "import('@libp2p/pnet').then(({ generateKey }) => generateKey(process.stdout))" > swarm.key
Copy

Programmatically

import fs from 'fs'
import { generateKey } from '@libp2p/pnet'

const swarmKey = new Uint8Array(95)
generateKey(swarmKey)

fs.writeFileSync('swarm.key', swarmKey)
Copy
