An SSH key consists of a pair of files. One is the private key, which you should never give to anyone. No one will ever ask you for it and if so, simply ignore them - they are trying to steal it. The other is the public key. When you generate your keys, you will use ssh-keygen to store the keys in a safe location so you can authenticate with.
Log in with an SSH private key on Linux and macOS
This article demonstrates how to use a private key to log in to a Linux速server by using a private key with a Terminal session on macOS速. However,you can follow the same process to use a private key when using anyterminal software on Linux.
- Jun 17, 2014 Now, let’s create our public/private key-pair. Type “ssh-keygen” into the Terminal and hit enter. At this point you’ll be asked to enter a name for your public/private key-pair. This name can be anything, but for this tutorial, I’ll use my first name with a suffix of rsa.
- SiteGround uses key pairs for SSH authentication purposes, as opposed to plain username and password. More information on SSH keys is available here. You can generate an SSH key pair in Mac OS following these steps.
- Jul 09, 2019 If the Private Key key file is lost, you’ll need to reissue your Certificate. Can I generate a new Private Key for my Certificate if I lose the old one?

- Jun 17, 2014 In the following article, we’re going to run through the process of creating a public/private SSH key-pair in OS X 10.9. Once this is done, we’ll configure our GitHub account to use the public key, create a new repository and finally pull this repository down onto our machine via SSH.

Prerequisites
To complete this process, you need the following software applications:
- SSH client software that is installed on your Linux or macOS operating system by default.
- Your favorite text editor. This example uses the vim text editor.
- Your private key. For more information about generating a key on Linux or macOS, see Connect to a server by using SSH on Linux or Mac OS X.
Log in with a private key
- Using a text editor, create a file in which to store your private key. This example uses the file deployment_key.txt.
- To edit the file in vim, type the following command:
- After the editor starts, press i to turn on insert mode.
- Paste your private key, such as the one in the following image, into the file.Be sure to include the BEGIN and END lines.
- To save your changes, press Esc.
- Type :wq to write the file and return to the command line.
- Run the following command to change the file permissions to 600 to secure the key. You can also set them to 400.This step is required:
- Use the key to log in to the SSH client as shown in the following example, which loads the key in file deployment_key.txt, and logs in as user demo to IP 192.237.248.66:
- When you are prompted to confirm the connection, type yes and then press Enter.
- If your SSH key requires a password, enter it when prompted to complete the connection.
