SSH keys are really neat! The DigitalOcean article on How To Set Up SSH Keys does an excellent job on explaining what SSH keys are and how to create them. In short, SSH keys are much more secure than password based authentication. In this post I will cover a few tips that I find myself frequently searching.
Create a 4096 bit SSH key. When creating the key, you can specify a passphrase.
ssh-keygen -t rsa -b 4096
Sometimes you might want to remove the passphrase from an SSH key. The command below will allow you to either remove a passphrase or add one to an existing SSH key.
ssh-keygen -p -f ~/.ssh/id_rsa
ssh-keygen -t ed25519
Sometimes I wrote posts for myself to easily reference and this is one of those times. However, I hope that this article is useful for others.
