![]() To do that provide the appropriate address using SSH, instead of HTTPS. Now you can safely perform a git clone with SSH key:.Type in the bash terminal ssh -T command. Go to your GitHub account settings > SSH keys section and then click the New SSH key button. ![]() To do so, open the bash terminal and type the ssh-keygen command.Ĭheck for two files with your keys: id_rsa and id_rsa.pub and copy them. Start with generating the aforementioned pair of keys. ![]() Every admin, team leader, CTO, or anyone responsible for these matters in the company should make sure that each local copy of the Git repository is only cloned with SSH key. If our local backups are connected via SSH, then we are not very interested in this password change and the connection to the remote repo will still be established as long as we have the correct key pair.ĭespite the fact that setting up an SSH connection requires a bit more work from us than the usual clone via HTTPS, it is still worth doing whenever we care about the security and protection of data in our repository. For example, the company, for security reasons, forces the GitHub password to be changed once a month. It allows you to use the terminal on Windows systems in the same way as in the Unix system family.Īnother benefit is that SSH keys are unlikely to be changed often, and certainly not as often as passwords. I will show you how to do it using this project: . Integrations with GitHub, GitLab, Bitbucket, and Azure DevOps make it swift and simple to clone, fork, and add remotes. In this case, we need to install some external tool that will enable us to work with this protocol. Unix systems have a built-in SSH module, while Windows, unfortunately, does not. Also, the principle of operation is very similar on each of these portals, so I will focus only on GitHub today as after that article you will be able to handle this process for other services on your own.īefore we try to do this, we first need to generate the aforementioned pair of keys. We can quite easily establish such a connection for GitHub, GitLab, and Bitbucket. To establish such a connection, we need a pair of keys: private (saved on our computer’s hard drive) and public, shared with the service we want to connect to. Importantly, such connections are encrypted. Secure SHell SSH is a communication protocol that enables a remote terminal connection, e.g. What is SSH?įirst, we need to know what SSH is to understand why we can clone repositories with it. It explains the principles of clone operation and further reading will be easier if you first understand the basics and the idea of cloning. I also encourage you to read this article: How to clone a repository. And this is what you will learn from this article – what is SSH and how to use it in our Git repositories. On the other hand, it turns out that not everyone uses appropriate security measures, or sometimes we just don’t know how to do it. Then, all the following will work.Each of us is aware of the importance of security in the IT world. Then these alternative names must be declared in ~/.ssh/config as well in order you to use these names to connect to via SSH. Copy the git fetch command in the check out your branch dialog. You should see something like this: Click Create branch, name the branch test-2, and click Create. Suppose 23.22.230.24 is the IP address of, and " my_ec2_host 23.22.230.24" is added in /etc/hosts. Go to your tutorial repository in Bitbucket and click Branches. ssh/config, you cannot directly SSH to alternative names (e.g., IP address or hostname alias defined in /etc/hosts) of the SSH server, unless you also add them explicitly to ~/.ssh/config. Note that the hostname (e.g., ) specified with ssh command must match with that declared in. Then you can SSH without explicitly specifying your private key with -i option. In that case, you can declare which private key to use for each SSH server, in your SSH configuration file which is found at ~/.ssh/config. However, things get complicated when you have multiple private keys. ![]() To specify a private key file in SSH from the command line, you can simply use -i option in the ssh command.Īssume that you want to access with a private key located in ~/.ssh/alice.pem: $ ssh -i ~/.ssh/alice.pem In the following, I describe how to do it. But what if you have many different servers, each of which happens to require different private keys? It will be nice for you to be able to automatically load a certain private key with a specific SSH server. It is straightforward to do so by using SSH's command line option. git config -global credential.helper store Save the username and password for a session (cache it) git config -global credential.helper cache You can also set a timeout for the above setting git config -global credential. If you connect to a remote server via SSH, which only accepts key authentication, you need to present your private key to the SSH server for authentication. Make Git store the username and password and it will never ask for them.
