SSH keys are an access credential used in SSH protocol (Secure Shell) which is a network protocol that helps to login from one computer to another securely, as well as to manage networks, operating systems, and configurations. This snippet is going to help you add an SSH key to the ssh-agent, generate a new SSH key, learn how to find the SSH key of your PC and how to connect it with your GitHub/bitbucket account. You can also find information on the use of SSH keys.

Now let's find out how we can checkout PC's SSH keys.

Checking PC's SSH Keys

In order to generate SSH keys for your Git repository, use the “ ssh-keygen ” command and specify the encryption algorithm that you want to use. $ ssh-keygen -t rsa -b 4096 -C ' email protected ' Note that it is recommended to generate your SSH keys in the “.ssh ” directory of your home directory. Jul 25, 2019 How to generate SSH keys for Git authorization Windows. Open file yourhomedirectory/.ssh/idrsa.pub with your favorite text editor. Open the file you’ve just created /.ssh/idrsa.pub with your favorite text editor. Linux (Ubuntu) Be sure that you don’t copy any whitespace while. If you don’t have a SSH public/private key pair you can generate it using the puttygen utility. From now on I’ll use%USERHOME% whenever I refer to your Windows user home folder, which depending on your Windows version may be located in.

Type ls -al ~/.ssh so as to see your ssh keys:

By default, the filenames of the public keys are one of the following:

Generate a new SSH key

Type this below, using your GitHub's account email:

The following text will show up after which you can hit the “Enter” button:

In this section, you can hit “Enter” again or type the secure passphrase (more about passphrase).

Adding an SSH key to the ssh-agent

Now let’s find out how we can add the SSH key to ssh-agent. Before adding, check your ssh keys or generate a new key.

Be sure ssh-agent is enabled:
Add your SSH key to the ssh-agent. If you used an existing SSH key rather than generating a new SSH key, you would need to replace id_rsa in the command with the name of your existing private key file:

How To Add SSH Key To Github Account

Log into your Github's account. In the top right corner of any page, click your profile photo, then click Settings.
In the user settings sidebar, go to SSH and GPG keys.
Click New SSH key.
Type Title and your SSH Key.

You can get your ssh key by typing below.

Now you have added your PC's SSH key to your Github's account.

Back up old SSH keys

If there are existing SSH keys, but you do not want to use them for connecting to Bitbucket Server, you should back up these old keys running the following:

Why we need SSH key (for Linux and OSX)

If you use Git and want to clone anything from remote repositories, you have to choose one of these two ways: HTTPS or SSH. If you use HTTPS, you have to type your account access every time you communicate with the remote repository, or change your configs and fill your account data (access). Another modern way is to use the SSH authentication method. It is used in many Version Control Systems to have command line access into your servers, etc. SSH key pairs can be used for authentication instead of passwords. Each key pair consists of a private key and a corresponding public key. When you use SSH key for Git, you inform Git that this PC is authenticated for that Github account, and it will never ask you about any access again because you have already given it your SSH key.

An SSH key is an access credential for the SSH (secure shell) network protocol. This authenticated and encrypted secure network protocol is used for remote communication between machines on an unsecured open network. SSH is used for remote file transfer, network management, and remote operating system access. The SSH acronym is also used to describe a set of tools used to interact with the SSH protocol.

SSH uses a pair of keys to initiate a secure handshake between remote parties. The key pair contains a public and private key. The private vs public nomenclature can be confusing as they are both called keys. It is more helpful to think of the public key as a 'lock' and the private key as the 'key'. You give the public 'lock' to remote parties to encrypt or 'lock' data. This data is then opened with the 'private' key which you hold in a secure place.

How to Create an SSH Key

SSH keys are generated through a public key cryptographic algorithm, the most common being RSA or DSA. At a very high level SSH keys are generated through a mathematical formula that takes 2 prime numbers and a random seed variable to output the public and private key. This is a one-way formula that ensures the public key can be derived from the private key but the private key cannot be derived from the public key.

SSH keys are created using a key generation tool. The SSH command line tool suite includes a keygen tool. Most git hosting providers offer guides on how to create an SSH Key.

Generate an SSH Key on Mac and Linux

Both OsX and Linux operating systems have comprehensive modern terminal applications that ship with the SSH suite installed. The process for creating an SSH key is the same between them.

1. execute the following to begin the key creation

This command will create a new SSH key using the email as a label

2. You will then be prompted to 'Enter a file in which to save the key.'
You can specify a file location or press “Enter” to accept the default file location.

3. The next prompt will ask for a secure passphrase.
A passphrase will add an additional layer of security to the SSH and will be required anytime the SSH key is used. If someone gains access to the computer that private keys are stored on, they could also gain access to any system that uses that key. Adding a passphrase to keys will prevent this scenario.

At this point, a new SSH key will have been generated at the previously specified file path.

4. Add the new SSH key to the ssh-agent

The ssh-agent is another program that is part of the SSH toolsuite. The ssh-agent is responsible for holding private keys. Think of it like a keychain. In addition to holding private keys it also brokers requests to sign SSH requests with the private keys so that private keys are never passed around unsecurly.

Before adding the new SSH key to the ssh-agent first ensure the ssh-agent is running by executing:

Once the ssh-agent is running the following command will add the new SSH key to the local SSH agent.

The new SSH key is now registered and ready to use!

Generate an SSH Key on Windows

Windows environments do not have a standard default unix shell. External shell programs will need to be installed for to have a complete keygen experience. The most straight forward option is to utilize Git Bash. Once Git Bash is installed the same steps for Linux and Mac can be followed within the Git Bash shell.

Windows Linux Subsystem

Modern windows environments offer a windows linux subsystem. The windows linux subsystem offers a full linux shell within a traditional windows environment. If a linux subsystem is available the same steps previously discussed for Linux and Mac can be followed with in the windows linux subsystem.
