sorry for the noob question, but I'm struggling to understand how they work.
So far, I've managed to create a id_rsa and id_rsa.pub file, I assume id_rsa.pub is the public key.
I should also mention I am using the hosting services 'OVH'. I have added the public key to the 'My SSH Keys' section.
The thing I can't grasp is how do I use it? Do I need to add the public key to my local windows machine for it to use it?
