Using SSH keys in Linux

Originally posted on February 14, SSH keys are a necessity for Python development when you are working with Git , connecting to remote servers and automating your deployments. Let’s walk through how to generate SSH key pairs, which contain both a public and a private key within a single pair, on Ubuntu Linux. Generating the Public and Private Keys Open up a new terminal window in Ubuntu like we see in the following screenshot. The ssh-keygen command provides an interactive command line interface for generating both the public and private keys.

Invoke ssh-keygen with the following -t and -b arguments to ensure we get a bit RSA key. Optionally, you can also specify your email address with -C otherwise one will be generated off your current Linux account: However, there are actually two files that will be generated: This prompt refers to the private key and whatever you enter will also generate a second file for the public key that has the same name and.

If you already have a key, you should specify a new filename. I use many SSH keys so I typically name them “test-deploy”, “prod-deploy”, “ci-server” along with a unique project name. Naming is one of those hard computer science problems, so take some time to come up with a system that works for you and the development team you work with! Next you will see a prompt for an optional passphrase: Enter passphrase empty for no 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 key so it is more secure. However, if you are automating deployments with a continuous integration server like Jenkins then you will not want a passphrase.

Be aware that it is impossible to recover a passphrase if it is lost. Keep that passphrase safe and secure because otherwise a completely new key would have to be generated.

Enter the passphrase or just press enter to not have a passphrase twice. You’ll see some output like the following: The key fingerprint is: What now? Now that you have your public and private keys, I recommend setting up a Python development environment with one of the following tutorials so you can start coding:

Command and Option Summary What Is ssh-keygen? Ssh-keygen is a tool for creating new authentication key pairs for SSH. Such key pairs are used for automating logins, single sign-on, and for authenticating hosts. The authentication keys, called SSH keys , are created using the keygen program. SSH introduced public key authentication as a more secure alternative to the older.
