If you use a passphrase then you will have to enter it each time you use the keys for authentication. When you generate the keys you will be asked for a ‘passphrase’. They will be put in your directory ~/.ssh, though you will probably be asked to approve or change this location. Run the command ssh-keygen from the Terminal.app (macOS) or console (Windows) to generate a public/private pair of keys. The new OpenSSH format ( openssh-key-v1) is only supported for ecdsa and ed25519. OpenSSH private keys of type rsa, dsa, ecdsa and ed25519 (in OpenSSL PEM format) are supported. Private keys containing a DSA or RSA private key in PEM format are supported (look for -BEGIN DSA PRIVATE KEY- or -BEGIN RSA PRIVATE KEY- in the file) and can be configured in the Bookmark or Connection panel. The public key, which is placed on the server you wish to gain access to, usually by the system administrator when your account is set up. Public-key authentication uses two keys:Ī private key that only you have that should be kept in a secure place and protected with a password Public-key authentication allows you to connect to a remote server without sending your password over the Internet. Also when opening a new connection using File → Open Connection…, IdentityFile and User parameters in the OpenSSH user config file are auto completed.ĭefaults write ch.sudo.cyberduck .enable true Resolves Too many authentication failures errors with servers limiting the number of attempted authentication requests.Ī bookmark will update its public key authentication setting from the IdentityFile configuration in ~/.ssh/config. Only try explicitly set private keys to authenticate but not all identities found in SSH agent. PreferredAuthentications to limit authentication methods tried to login. ProxyJump to connect via SSH tunnel through bastion server. Specifies the UNIX-domain socket used to communicate with the authentication agent. IdentityAgent for public key authentication. IdentityFile for public key authentication.

The following configuration options from ~/.ssh/config are supported for SFTP connections: This does not apply to the Mac App Store version which does store key fingerprints in the preferences. Public key fingerprints are checked against and written to ~/ssh/known_hosts when accepted. OpenSSH Configuration Interoperability  Public Key Fingerprints  If you have access to a server using a secure shell ( SSH2), most probably sftp-server is also installed and configured and you can connect using SFTP. All connection profiles are available through the Preferences → Profiles tab.
