This is both a more convenient and more secure method of user authentication than traditional username. With this method, your SSH-keys are used to identify a user logging into an SSH server through public-key cryptography and challenge-response authentication.
Now the process of adding your passphrase to the Keychain and retrieving it is automated whenever you use ssh or your ssh key is used for authentication. SSH-keys are a means of identifying a user within the SSH protocol (used by SFTP). On Mac, add the following to the file ~/.ssh/config (you may need to create this file).Īlso make sure to properly set the permissions for this file: chmod 600 ~/.ssh/config Examples of SSH agents include Pageant (puTTY/Windows), Keychain (Mac), and ssh-agent (Linux & Mac). You can think of this as being similar to a "password manager" as you would use for a web browser. You need to enter your passphrase once to unlock your key, but after unlocking your key it will authorize multiple SSH connections when you use an SSH agent to temporarily retain your credentials. SSH into the RCE ( ssh or open a Terminal via an NX session.Ĭat ~/id_rsa.pub > ~/.ssh/authorized_keysĮxit the RCE and log in via SSH or PuTTY, and you no longer need to type your password. FileZilla, WinSCP).Ĭomplete the "On the RCE" steps below to authorize the new key. Upload your public key to the RCE using SFTP (e.g. You can save it in the same location as the public key. Specify a Key passphrase and repeat it under Confirm passphrase.Ĭlick on Save public key and save it as id_rsa.pub.Ĭlick on Save private key and save it as id_rsa. Under Key comment, enter your email address. Generate entropy/randomness by moving the mouse around as instructed. Select SSH-2 RSA under Type of key to generate and specify 4096 as the Number of bits in a generated key. Scp ~/.ssh/id_rsa.pub the "On the RCE" steps below to authorize the new key. Upload the public key file ~/.ssh/id_rsa.pub to the RCE using an SFTP client like Filezilla, or run: The keys are created in ~/.ssh/ (inside your home directory). Use a passphrase for appropriate security.
