Examples

Private Networks with IPFS

Private Shared Keys

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

/key/swarm/psk/1.0.0/
/base16/

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 libp2p-pnet

If you have libp2p locally, you can run the following from the projects root.

node ./src/pnet/key-generator.js > swarm.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 "require('libp2p/src/pnet').generate(process.stdout)" > swarm.key

Programmatically

const writeKey = require('libp2p/src/pnet').generate
const swarmKey = new Uint8Array(95)
writeKey(swarmKey)
fs.writeFileSync('swarm.key', swarmKey)
