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.
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.
GitHub.com Authentication Connecting to GitHub with SSH Generating a new SSH key and adding it to the ssh-agent Generating a new SSH key and adding it to the ssh-agent After you've checked for existing SSH keys, you can generate a new SSH key to use for authentication, then add it to the ssh-agent. As a GitHub user, you may want to add and setup SSH keys to your repositories in order for them to be easily accessible. SSH keys are one of the two authentication methods used on GitHub in order to securely log in and write changes to repositories.

Create a SSH key pair (RSA) in Ubuntu 14.04. GitHub Gist: instantly share code, notes, and snippets.
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!
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:

Hi there! This post will be pretty straightforward and will cover Windows, Mac, and Linux, so if you don’t know how to do it already, read on.
Just follow these 5 steps:
Note: your_home_directory is either C:Usersyour_username (on Windows Vista / 7 / 8 / 10), or C:Documents and Settingsyour_username (on Windows XP)
Follow these 5 steps:
Follow these 5 steps:
When you create private/public SSH keys on your machine (that’s what you did in the above steps), it’s not enough. You need to give your public key to the repository in order to pair the Git server with your local machine (that’d be steps 4. and 5. above).
Most of the popular repositories will give you web interface access to the application, and here’s how it looks like on Github:
After this step, you’re ready to start using Git.
I hope this wasn’t too complicated to follow, and also I hope it was helpful to someone!
Cheers!
