First cool thing that everybody knows already: Mac OSX is based on Unix so you get ssh out of the box. Second cool thing you may not know: OS X 10.5 actually also comes with an ssh key agent (ssh-agent). That means that, without any additional softwar. Creating a SSH Public Key on OSX¶. You generate an SSH key through Mac OS X by using the Terminal application. Once you upload a valid public SSH key, Gerrit can authenticate you based on this key. When you generate your keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your server. To generate SSH keys in Mac OS X, follow these steps: Enter the following command in the Terminal window. Ssh-keygen -t rsa This starts the key generation process.

Course details
Secure Shell (SSH) offers a safe way to communicate with a server and to connect to systems remotely. Consequently, SSH is a vital skill for anyone who works in IT. In this short course, Scott Simpson explains what SSH is and shows how to connect to an SSH server from different operating systems. He also demonstrates how to transfer files via SSH File Transfer Protocol (SFTP) and secure copy (SCP), and how to set up your own SSH server on Linux and Mac OS X.

“- To generate a key pair on a Mac or Linux machine, in the terminal I'll write ssh-keygen -t rsa to specify the RSA encryption algorithm type. RSA is a widely used encryption algorithm. This will start up an interactive series of prompts asking you where you want to store the key. In this case, I'll leave it as the default. You could rename the key if you anticipate having many different keys. I'll press enter to accept this recommendation. The next option is whether to set a pass phrase. This might seem a little counter intuitive, given that we're using a key to avoid using a password for the log in, but this is the pass phrase to unlock the key, not to log directly into the remote server. Keys are great but if your private key gets stolen, anyone with that file will be able to log into that server as you. Setting a password on the key helps makes it harder for an attacker to do this. Every time you need to unlock the key to use it, you'll need to type the password, so make it…
