bitbeam

A 1-1 end-to-end encrypted internet pipe powered by Bitswarm and Noise

npm install @web4/bitbeam

Usage

const Bitbeam = require('@web4/bitbeam')

// 'neznr3z3j44l7q7sgynbzpdrdlpausurbpcmqvwupmuoidolbopa' is 32-byte unique passphrase
// to find the other side of your pipe.
// once the other peer is discovered it is used to derive a noise keypair as well.
const beam = new Bitbeam('neznr3z3j44l7q7sgynbzpdrdlpausurbpcmqvwupmuoidolbopa')

// to generate a passphrase, leave the constructor empty and bitbeam will generate one for you
// const beam = new Bitbeam()
// beam.key // <-- your passphrase

// make a little chat app
process.stdin.pipe(beam).pipe(process.stdout)

CLI

Part of the BitWeb CLI

Provided here as a standalone CLI as well.

First install it

npm install -g @web4/bitbeam

Then on one machine run

echo 'hello world' | bitbeam

This will generate a phrase, eg "neznr3z3j44l7q7sgynbzpdrdlpausurbpcmqvwupmuoidolbopa". Then on another machine run

# will print "hello world"
bitbeam neznr3z3j44l7q7sgynbzpdrdlpausurbpcmqvwupmuoidolbopa

That's it! Happy piping.

API

const stream = new Bitbeam([key][, options])

Make a new Bitbeam duplex stream.

Will auto connect to another peer using the same key with an end to end encrypted tunnel.

When the other peer writes it's emitted as data on this stream.

Likewise when you write to this stream it's emitted as data on the other peers stream.

If you do not pass a key into the constructor (the passphrase), one will be generated and put on stream.key.

options include:

• dht: A DHT instance. Defaults to a new instance.

stream.key

The passphrase used by the stream for connection.
