Heimdallr

finding public ssh keys with ease

This tool is intended to get developers public keys

• via a limited ssh-server on the local host (which can be accessed by ssh-copy-id)
• or by fetching them from github, were the developers may've left them.

Getting Started

These instructions will get you a copy of the project running on your local machine, for development and testing purposes.

See deployment for notes on how to install the project on your system.

Prerequisites

• gcc or another compiler
• libcurl to fetch api responses
• libssh to run the ssh-server
• json-c in order to interprete api responses
• openssl for generating ssh keys

Optional

• cmocka for make check

Compiling

A step by step series of examples that tells you, how to get a development env running.

clone this repo

git clone https://github.com/AiyionPrime/heimdallr.git

cd into the project and build it

cd heimdallr
make

Take a look at eg. my pubkey(s), by calling heimdallr with the user flag

./heimdallr -u aiyionprime

Alternatively start a ssh-server (eg. on port 1234), which others can fill with pubkeys via ssh-copy-id:

./heimdallr -p 1234

Your coworkers can then use ssh-copy-id like they would do with ordinary ssh-servers:

ssh-copy-id -p 1234 <the-ip-of-your-device>

Hint: You can list your current IPs with

hostname -i

Deployment

From source

Deploying this on a live system can be done by running the build steps followed by

sudo make install

Using homebrew

brew install aiyionprime/tools/heimdallr

Using the arch user repository

yaourt -S heimdallr

If you like this tool, don't forget to vote for it, so others can find it, too!

Alternatively: Install the latest development release

yaourt -S heimdallr-git

Contributing

We're open for ideas improving the workflow of sharing ssh public keys, so if you've got a good one, feel free to contact me about it.

Testing

In order to run the small amount of available unittests, run

make check

in the source directory.

The expected output is something like: [==========] Running n test(s). ... [ PASSED ] n test(s).
