Regenerating a lost public OpenSSH key
A lost the public SSH key can be just regenerated if you still have the corresponding private SSH key.
Use the OpenSSH command below to print the public key:
$ ssh-keygen -t dsa -y Enter file in which the key is (/home/username/.ssh/id_dsa): Enter passphrase: ssh-dss (Your key will be shown here)
If you have lost the private key, you will need to generate a new key pair completely.
