Install

npm install libp2p-tls

Usage

const tls = require('libp2p-tls')

API

tag

The current tls tag, usable in multistream.

encrypt(id, key, insecure[, callback])

• id: PeerId - The id of the node.
• key: RSAPrivateKey - The private key of the node.
• insecure: PullStream - The insecure connection.
• callback: Function - Called if an error happens during the initialization.

Returns the insecure connection provided, wrapped with secio. This is a pull-stream.

This module uses pull-streams

We expose a streaming interface based on pull-streams, rather then on the Node.js core streams implementation (aka Node.js streams). pull-streams offers us a better mechanism for error handling and flow control guarantees. If you would like to know more about why we did this, see the discussion at this issue.

You can learn more about pull-streams at:

• The history of Node.js streams, nodebp April 2014
• The history of streams, 2016
• pull-streams, the simple streaming primitive
• pull-streams documentation

Converting pull-streams to Node.js Streams

If you are a Node.js streams user, you can convert a pull-stream to a Node.js stream using the module pull-stream-to-stream, giving you an instance of a Node.js stream that is linked to the pull-stream. For example:

const pullToStream = require('pull-stream-to-stream')

const nodeStreamInstance = pullToStream(pullStreamInstance)
// nodeStreamInstance is an instance of a Node.js Stream

Roadmap

• [ ] Add backwards-compatible tls1.3 support
• [ ] Add a parameter to let the clients choose between ECC and RSA crypto?
• [ ] Add browser support
