Public key authentication is a way of logging into an SSH/SFTPaccount using a cryptographic key rather than a password. The .pub file is your public key, and the other file is the corresponding private key. Enter an empty password if you want to remove the passphrase. If you have more keys, you must specify which key to use using the -i option to ssh. Then in the Key Generator window, check that the Type of key to generate at the bottom is set to SSH-2 RSA. Ask the end user to provide the public key by typing the following command: cat ~/.ssh/id_rsa.pub Once the key has been copied, it is best to test it: The login should now complete without asking for a password. Steps to setup secure ssh keys: Create the ssh key pair using ssh-keygen command. You need to have the port command installed. When SSH key generation is complete, you see the public key and a few other fields. For example, with SSH keys you can 1.
