SSH Key Management

With this program you'll be able to add your ssh key through a web-ui.

The keys will be store in a json file.

A small script installed on all hosts will pull the json file and add keys for concerned users.

Note : the json database is only store on the web-ui server.

                         [3]

• [1] - adding the ssh keys to the json database through the web-ui
• [2] - agent ask the master to get the json
• [3] - master send the json and the agent apply all modification itself

⚠️ not for production, use at your own risk ⚠️

Todo List :

• Configuration file for the master
• Simple and fonctionnal web-ui
• Manage key through json
• Possibility to disable key
• Improve security and clean code
• Add possibility to list all the key in the web-ui
• Add possibility to delete the key directly on the web-ui

Prerequisites

# apt-get install jq git php5-fpm nginx

Installation

Master

Create an user who can manage the SSH-Key and specify the home (here /srv/ssh-management) and clone the repo :

# useradd -m -d /srv/ssh-management ssh-management
# cd ~
# git clone https://github.com/ab-a/sshkey.git 
# cp -r sshkey/master/web-ui /srv/ssh-management

Agent

The agent will be run with the user root (or any user with root to have the right to edit all .ssh/auhorized_keys.). Generate an SSH Key and push it to the master server :

# ssh-keygen -t rsa -b 4096

The agent will ask the master, pull and parse the json and set the keys.

The Web-UI

The web-ui allows you to push your SSH key into the json.
