#MAC SSH KEYGEN HOW TO#

You should see the following response after typing the above command: Generating public/private ed25519 key pair.Įnter file in which to save the key (/home/user/.ssh/id_ed25519): How to generate an RSA SSH key pair

The -C and the comment in quotations is optional, but should be used if you’re going to generate more than one pair. To generate ED25519 SSH key you will need to run the following terminal command: ssh-keygen -t ed25519 -C ''

For MacOS, Windows PowerShell or Linux terminals instructions, please see the documentation.

I’m assuming you are using GitBash, as it is the terminal that is supplied with git. One thing you won’t find in the above page, since it shows up in another place in the documentation, is where to type in the commands.

The official documentation is fairly comprehensive, but for completeness sake, I will walk you through the process. How to generate an SSH key pair for your GitLab account No system connected to the internet is truly secure, but with an SSH key you greatly reduce the chance of human error giving away your access privileges. Humans aren’t very good at remembering a large number of secure passwords so they tend to reuse passwords over multiple sites, resulting in many vulnerabilities.

Why should you use SSH keys in Gitlab?Īside from the comfort provided by not having to submit your username and password for each action you take, SSH keys are generally much more secure than a username and password. Do note that by default, a 1024 bit key is generated, so make sure to not use the default. Although it is recommended you use an SSH key of at least 2048 bits. However, if you have a good reason to, there are also RSA SSH keys, which would work just as well on GitLab. It is generally recommended you use ED25519 SSH keys, which are more secure, and should be available on any system.

Whenever you push code to the hosted repository, it will trigger the pipeline and it will be automated from there, and that action might be scheduled to run many times a day. The vast majority of actions you will be taking on GitLab via SSH will be pushing changes from your local git repository to the hosted repository on GitLab.Īlthough there are other actions you can take, such as starting the GitLab CI/CD pipeline, once started you’re not going to need to interact with the GitLab runner often. SSH keys are one of the choices for authentication against GitLab servers. Once this is set up, the server can ask the user for proof of identity using the public key and the user can prove it using the private key. The private key, however, is kept by the user and should not be copied or exposed in any way. It doesn’t really matter if it can be viewed as it is public information. When using an SSH key pair as a method of authentication, the public key is stored on the server. Private Key – Can be used as proof of identity, and is used to authenticate a user’s connection to the server. Public Key – Can be used to encrypt data in such a way so only the holder of the corresponding private key can decrypt it.

Each SSH key pair has a public and a private key. In order to communicate over SSH (Secure Shell), you must have an SSH key pair. In this article, we’ll review what SSH keys are in the context of GitLab authentication, how to create them, and how to keep them safe. Moreover, when using CI/CD and automation tools, SSH keys are a much better choice for securely authenticating your GitLab account. This can result in quite a lot of prompts. Things tend to get a little more complicated when sending Git commands to a server over HTTPS demands the user submit their username and password in order to perform each action.
