Lets say you have a private/public key pair that you use to login to your server via SSH and you lose the public key, either it was deleted or corrupt and you don’t want to have to regenerate a new pair what options do you have? In this post I will demonstrate how to regenerate a public key from the corresponding private key that you still have.

Command Breakdown:
‘ssh-keygen -y’ : tells the prorgram ssh-keygen to output a public key Windows xp installation id key generator.
‘-f user@myserver.key’: references the key file user@myserver.key to generate the public key from
‘> authorized_keys’: instead of printing the output to the console redirect the output (public key) to a file named ‘authorized_keys’
Copy public key to your server
Now we will need to take our authorized_keys file and store it on the server, if we can currently login via SSH to our server we can use rsync over ssh to securely copy the public key to the server, Although this key is displayed to anyone who attempts to login to your server it is smart to use SSH or another secure method to copy it up to the server to ensure that the key is not tampered with while it is being transmitted.
