About

https://travis-ci.org/mvk/sshadder.svg?branch=master

ssh keys manager for multiple password protected keys. Stop adding them manually.

What it does

Defines key bundles and allows adding all of keys in the bundle to a running ssh-agent

What it does not

  • aims at command line only, no graphic desktop/dependency. no DBus (no need)
  • does not compete with full-on private keys managers like Seahorse
  • ssh-agent management. You run it, and have SSH_AUTH_SOCK properly pointing to the desired SSH Agent process

Installation

Run in virtualenv:

pip install sshadder

NOTE: The crypto path is not yet vetted, so do not install this system-wide just yet. Honestly :)

Usage

Prerequisites:

Running and visible ssh-agent

Normally:

Run:

sshadder

Please refer to --help, which shows default locations it’s looking for the JSON files.

Initialization:

Run:

sshadder -i

The text will guide you to give a master password (not saved anywhere), and then iterate over

  • key file path
  • key password

When you’re ready, choose ‘s’ option to save and quit.

What is actually happening

Given config file .sshagent.json and master password, the utility adds all the ssh key files using their passwords JSON file keeps the key passwords encrypted using simple-crypt package. Each password is encrypted and then encoded using Base64 and added to the key item. The text file is kept as it is now - text file.

Not sure how REALLY safe it is, but it is safer than plain text shell scripts.

Current known security problems

As long as pexpect.spawn() is used here, it means if your system is compromised and rogue user can access your /proc, they probably can see the passwords passed to ssh-agent in clear text. If this is VERY unsafe for you, please send a patch/pull request :)

Contributing

Patches/pull/feature requests are welcome to improve the code/fix bugs. Note I’m quite a busy person, so if you can fix/add it - send me a patch/pull-request.
