Creating an SSH Key Using “ssh-keygen” and Connecting to a Remote Server with It

SSH key; It is a key that provides secure password authentication. In cases where the number of connected servers is high and many different passwords are used on each server, the user must use a password manager or remember each password one by one. SSH key is used to facilitate such operations. Once the SSH key is introduced, servers do not request a password. In this article, we will generate SSH Key by using “ssh-keygen”. Then, we will connect to the Rancher server we created in AWS Cloud, by using this SSH key we created. We will do them practically and step by step.

Topics we will cover:

1. What Is The “ssh-keygen”
2. Creating A Key Pair On The Local Machine By Using “ssh-keygen”
3. Copying The Public Key To The Remote Server
4. Connecting To The Remote Server By Using The SSH keys
