Sharing public keys

To be able to login into our shared server, you need to share your PUBLIC key publicly - which is paired with your PRIVATE key saved locally on your computer (which you never share with anyone, and can be additionally password-protected). 

Your PUBLIC key can be shared via our pad: https://pads.ccc.de/servlab

To create the keypair, you can use Linux-based ssh-keygen or other solutions. More on ssh-keygen use is available here.
