Generate SSH key to access private repositories

Generate a SSH key

On your terminal (from your personnal computer or from the cluster), type:

ssh-keygen

This will create a folder in your home directory called .ssh containing a file named id_rsa.pub.

Add this public key on your Github account

• Copy the full line starting from “ssh-rsa…” in .ssh/id_rsa.pub.
• In Github, got to Settings, SSH and GPG keys. Then click on New SSH key. Give it a name and paste the line ssh-rsa.... Then click on Add SSH key.

You’re done!

You can make several SSH keys from your different devices, or you can use the same one for all. It that case you have to copy your .ssh folder into the home directory of the other devices (for instance on the HPC clusters).
