Using SSH Keys for Secure Access

Understanding the creation and exchange of SSH keys is a key concept to grasp as a System Administrator. In this lab, we will generate keys on two systems using the ssh-keygen utility and learn how to exchange and verify the keys with a remote system, using `ssh-copy-id` and associated key files on each. At the end of this lab, we will understand how to create secure keys for remote access, how to exchange them, and where to store them on each system involved in the chain.

Generate a New SSH Key Pair for cloud_user on server1
Using the ssh-keygen command, create a new key pair for the cloud_user user on server1:
```
ssh-keygen
```
Challenge

Copy the SSH Key from server1 to server2
Using the ssh-copy-id command, transfer the public key to the remote user's account:
```
ssh-copy-id cloud_user@server2
```
Challenge

Log into server2 with SSH
If the previous step was done correctly, we should be able to log into server2 without using a password:
```
ssh cloud_user@server2
```
Challenge
