I set a passphrase when creating a new SSH key on my laptop. But, as I realise now, this is quite painful when you are trying to commit (Git and SVN) to a remote location over SSH many times in an.
1. The first thing that we need to do is create an SSH key pair to use. Creating this key pair will allow us to add the public key to GitHub. Open a terminal and enter the following command to create the SSH keypair:
2. After entering the command, a prompt appears with a default file path confirmation. Press Enter to accept the default file path.
3. Next, a password prompt appears. Our goal is convenience, since our public key is being created exclusively for GitHub. Windows xp sp3 product key generator free download for mac. Leave the passphrase empty and press Enter.
4. Another prompt appears, this time asking for the passphrase confirmation. Leave this prompt blank as well and press Enter.
5. After passphrase confirmation, our SSH key pair is created and saved within the default file path that we accepted in step 2 of this tutorial. We will need to copy the entire contents of our public key to add to GitHub. To display the contents of the public key, enter the following command into the terminal:
6. The output of the previous command should display the contents of the public key like in the image below.
7. Highlight and copy the entire output of the previous command. Every part must be copied for the SSH key to work when added to GitHub.
8. Now that the public SSH key has been copied to the clipboard, open a web browser and navigate to GitHub, then log in to your account.
9. Click the account icon on the navigation bar on the top-right of the page. Select ‘Settings’ from the dropdown menu that appears.
10. Select ‘SSH and ‘GPG keys’ from the selection pane on the left of the page.
11. Click the green, ‘New SSH key’ button on the top-right of the page.
12. We are taken to the ‘Add New SSH Key’ page. First, enter an identifying title for the SSH key so discerning which computer the matching private key is on is easy.
13. Finally, paste the public SSH key that was copied in step 7 of this tutorial into the ‘Key’ text field.
14. Click the green, ‘Add SSH key’ button to finish the process.
15. Success! The new public SSH key has been added to the GitHub account and can now be used to simplify and secure your work.
SSH keys are a necessity for Python development when you are working withGit, connecting to remote servers and automating yourdeployments. Let's walk through how to generate SSHkey pairs, which contain both a public and a private key within a singlepair, on Ubuntu Linux.
Generating the Public and Private Keys
Open up a new terminal window in Ubuntu like we see in the followingscreenshot.
The
ssh-keygen
command provides an interactive command line interface forgenerating both the public and private keys. Invoke ssh-keygen
with thefollowing -t
and -b
arguments to ensure we get a 4096 bit RSA key.Optionally, you can also specify your email address with -C
(otherwiseone will be generated off your current Linux account):(Note: the
-o
option was introduced in 2014; if this command fails for you, simply remove the -o
option)The first prompt you will see asks where to save the key. However, there areactually two files that will be generated: the public key and the privatekey.
This prompt refers to the private key and whatever you enter will alsogenerate a second file for the public key that has the same name and
.pub
appended.If you already have a key, you should specify a new filename. I use manySSH keys so I typically name them 'test-deploy', 'prod-deploy', 'ci-server'along with a unique project name. Naming is one of those hard computerscience problems, so take some time to come up with a system that works foryou and the development team you work with!
Next you will see a prompt for an optional passphrase:
Whether or not you want a passphrase depends on how you will use the key.The system will ask you for the passphrase whenever you use the SSH keyso it is more secure.However, if you are automating deployments with acontinuous integration server likeJenkins then you will not want a passphrase.
Be aware that it is impossible to recover a passphrase if it is lost. Keepthat passphrase safe and secure because otherwise a completely new key wouldhave to be generated.
Enter the passphrase (or just press enter to not have a passphrase) twice.You'll see some output like the following:

Your SSH key is now generated and ready to use!
What now?

Now that you have your public and private keys, I recommend settingup a Python development environment withone of the following tutorials so you can start coding:
