SSH keys are a way to identify trusted computers, without involving passwords. The steps below will walk you through generating an SSH key and adding the public key to the server.
Step 1: Check for SSH Keys
First, check for existing SSH keys on your computer. Open Git Bash, Cygwin, or Terminal, etc. and enter:
Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following:
- id_dsa.pub
- is_ecdsa.pub
- id_ed25519.pub
- id_rsa.pub
If you see an existing public and private key pair listed (for example id_rsa.pub and id_rsa) that you’d like to use, you can skip Step 2 and go straight to Step 3.
Install the necessary plugins for the repository (ex: GitHub install GitHub and GitHub Authentication plugins) in Jenkins. You can generate a key with Putty key generator, or by running the following command in git bash: $ ssh-keygen -t rsa -b 4096 -C [email protected].

May 10, 2018 Next step will be to produce the public/private key for the user dan on the remote server, $ ssh-keygen -t rsa -f forjenkinskey. Here, forjenkinskey is the name of the keys that will be generated. There will be two files ‘forjenkinskey’ & ‘forjenkinskey.pub’.
Step 2: Generate a new SSH key
With your command line tool still open, enter the text shown below. Make sure you substitute in your email address:
You’ll be asked to enter a passphrase, or simply press Enter to not enter a passphrase:
![Generating ssh keys for the jenkins user Generating ssh keys for the jenkins user](/uploads/1/2/6/4/126495227/593200895.png)
After you enter a passphrase (or just press Enter twice), review the fingerprint, or ‘id’ of your SSH key:
Step 3: Add your key to the ssh-agent
To configure the ssh-agent program to use your SSH key, first ensure ssh-agent is enabled.
If you are using Git Bash, turn on the ssh-agent with command shown below instead:
Jenkins Github Ssh Private Key
Then, add your SSH key to the ssh-agent:
Step 4: Add your SSH key to the server
To add your public SSH key to the server, you’ll copy the public SSH key you just created to the server. Substitute “username” with your username on the server, and “server.address.com” with the domain address or IP address of your server:
Generate Ssh Key Jenkins User
The server will then prompt you for your password:

That’s it! You should now be set up to connect to the server without having to authenticate.
