Add Keys to ssh-agent You can use the utility ssh-add to add keys to your local agent. All you’ll have to do is make sure your keys are added to ssh-agent and configure ssh to use forwarding. Obsessing over using the right magic words in your crypto config is at best a waste of time, and risks either making a mistake that reduces security, or more often distracting you from taking care of the things that actually do matter, like managing your key(s) and verifying the host authenticity. On Mac and Linux, SSH agent forwarding is built into ssh, and the ssh-agent process is launched automatically. The OpenSSH developers are pretty cautious - some would say overly so - and the defaults they set are already more than 'strong' enough. See the man page on your system or on the web, and search for existing Qs here or maybe superuser I know I've seen several.Īlthough it should be noted this won't improve security. Although that Q doesn't note that on client side, in /etc/ssh/ssh_config or ~/.ssh/ssh_config, you can configure either a global setting for all 'hosts' (servers), or different settings for different hosts and/or userids using the Host or Match syntax. On the client, server, or both, as described in the Q linked in a comment. You configure the program, not the key, for those elements. While generating the openssh key, how I do I tell what cipher, MAC and key exchange it should use? You can drag this icon to your dock for easy access. Double click on the Terminal application. And you configure or default the algorithms the client's key can use, as well as any non-publickey methods. If you want a powerful SSH client, then XSHELL could be the best bet for you. Step 1: Open Terminal In Finder, open the Applications folder and double click on the Utilities folder. And depending on the server, the client (only!) may use other authentication methods like password (often) or GSS (rarely) instead of (any of) the publickey algorithms.Ĭonversely, on a server, you can generate key(s) for particular algorithms, but in practice most servers automatically generate all key types, and provide whichever one(s) the client(s) request. Thus, on a client, you optionally generate one or more key(s) each using a particular algorithm aka 'type' -t (RSA, DSA - formerly, ECDSA, Ed25519), while you configure or default the algorithm(s) you will accept from the server. And while those three elements are functionally symmetric, authentication can be different for each direction. Open the Terminal App on Your MacBook You can do this by searching terminal using the Spotlight search option of your computer or navigating through Applications > Utilities > Terminal. The keys you manually generate with ssh-keygen (or equivalent) are used for authentication only, and have no effect at all on the three protocol elements you listed. There is a fourth major part of the SSH protocol: authentication. Is there any other important part for configuration in openssh?
