Suppose I have a SSH keys pair, but I’ve deleted the public key. I have the private key only. How can I regenerate public key from private key ?
man ssh-keygen says:
-y This option will read a private OpenSSH format file and print an OpenSSH public key to stdout.
The following command will generate a public key for you:
ssh-keygen -f ~/.ssh/id_rsa -y > ~/.ssh/id_rsa.pub
