Hypershell

A command-line interface for generating and connecting to peer-to-peer, end-to-end encrypted shells.

Installation

Install with npm:
npm install -g hypershell

Basic usage

Create a P2P shell server.
hypershell-server [options]
options include:

-f <filename>

~/.hypershell/peer
--firewall <filename>
List of allowed public keys.

hypershell [options] <server public key>
options include:

Setup

First, create a key with the default filename:
hypershell-keygen
Client
Now, you can connect to servers (provided they allow your public key):
hypershell <server public key>
Server
To create a server:
hypershell-server
~/.hypershell/firewall will be automatically created as an empty file. That means all connections are denied by default.
You can allow public keys in real time by adding them to the firewall list.

Known peers

There will be a file named ~/.hypershell/known_peers.
Add named peers to the file, for example:
# <name> <public key>
home cdb7b7774c3d90547ce2038b51367dc4c96c42abf7c2e794bb5eb036ec7793cd
Utilize hypershell home to eliminate the need for constantly providing the full public key.

Multiple keys

To have multiple servers, you need multiple keys.
Generate another key:
hypershell-keygen -f ~/.hypershell/my-server
Create a new shell server:
hypershell-server -f ~/.hypershell/my-server --firewall ~/.hypershell/my-server-firewall
The client also accepts -f if required.
