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.

Click Generate Key. CPanel generates the public and private keys and saves them in the /home/ username /.ssh directory, where username represents your A2 Hosting account username. Click Go Back. Under Public Keys, locate the name of the key you just created. Under Actions, click Manage. Click Authorize, and then click Go Back. Generating a new SSH key. Open Terminal Terminal Git Bash. Paste the text below, substituting in your GitHub Enterprise email address. $ ssh-keygen -t rsa -b 4096 -C 'youremail@example.com' This creates a new ssh key, using the provided email as a label. Generating public/private rsa key pair.

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.

• 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.
• ON windows if you have git for windows installed, run git-gui. Then click Help then click Show Ssh Key, then click Generate Key. Then click Help then click Show Ssh Key, then click Generate Key. While you're at it, then copy to the clipboard, and then go to your Gitlab account page and add the SSH key to your Gitlab account's ssh settings.
• Client authentication keys are separate from server authentication keys (host keys). A keypair consists of a private key and a public key, which are separate. A private key should never be sent to another party. It is private. If this is the first time you are using public keys, we recommend the page Public keys in SSH. Generate public/private.
• Nov 05, 2019 First we need to generate key pair. Type this command on Git Bash: ssh-keygen -t rsa. For now, we can just press Enter to use default key name and empty passphrase. ‘idrsa’ is the private key, and ‘idrsa.pub’ is the public key. Next we want to put the public key to the remote server.
• How SSH key authentication works. SSH public key authentication works with an asymmetric pair of generated encryption keys. The public key is shared with Azure DevOps and used to verify the initial ssh connection. The private key is kept safe and secure on your system. Set up SSH key authentication.

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.

Summary

SSH keys are used to authenticate secure connections. Following this guide, you will be able to create and start using an SSH key. Git is capable of using SSH keys instead of traditional password authentication when pushing or pulling to remote repositories. Modern hosted git solutions like Bitbucket support SSH key authentication.

Git™ Version Control

Valid for versions 82 through the latest version

Last modified: April 9, 2020

Overview

The Git™ Version Control feature allows you to easily host Git repositories on your cPanel account. You can use Git to maintain any set of files (for example, a website’s files and assets, a software development project, or simple text files). For more information, read our Guide to Git - How to Set Up Deployment documentation and Git’s Documentation.

The system adds a post-receive hook to all cPanel-managed repositories. For more information, read Git’s githooks documentation.

Git on the command line

Without shell access, you can only create, clone, delete, and view repositories.

If your cPanel account includes shell access, you can also use Git from the command line. You must use the command line to perform the following tasks:

• SSH configuration in order to clone private repositories. For more information, read our Guide to Git - Set Up Access to Private Repositories documentation.
• The use of multiple remote repositories. We recommend this use for advanced Git users only.

You can use cPanel’s Terminal interface (cPanel >> Home >> Advanced >> Terminal) to access the command line from within the cPanel interface.

Repositories

• When you clone a repository, the system may require a large amount of time to complete. The list of repositories will disable the options for the repository and will only display the repository name, repository path, and a progress message.
• If you add or remove Git repositories via the command line, you may see an incorrect list of repositories in this interface. Currently, only repositories that you created in this interface will appear in the list.

The Repositories table lists the following information for all of your account’s cPanel-managed Git repositories:

• Repository — The repository’s display name.
• Repository Path — The repository’s directory.

Generate Key In Cpanel For Gita

You can also perform the following actions:

• Manage — Click to update the repository’s cPanel-managed settings or pull or deploy changes.
• History — Click to open the Gitweb interface in a new browser tab. Gitweb allows you to browse the repository and view its history and contents.
• Remove — Click to remove cPanel’s management of the repository. A confirmation message will appear. Click Remove again to delete the repository.

  When you remove cPanel’s management of a repository, the repository will no longer appear in the interface, and you cannot use cPanel to deploy it. However, the system will not delete the repository directory or its data. To fully delete repository data, use cPanel’s File Manager interface (cPanel >> Home >> Files >> File Manager) or your preferred method to manually delete the files.

  When you clone a repository, the system may require a large amount of time to complete. The list of repositories will disable the options for the repository and will only display the repository name, repository path, and a message about the clone’s progress.

Create a repository

To create a new repository, perform the following steps:

1. Click Create in the top-right corner of the interface. A new interface will appear.

2. Select whether to clone an existing repository, create a new one, or add an existing one to the list of cPanel-managed repositories:

   • To clone an existing repository, ensure that the Clone a Repository toggle is enabled. Then, enter the clone URL for the repository that you wish to clone in the Clone URL text box.

     To clone private repositories, you must perform additional steps. For more information, read our Guide to Git - Set Up Access to Private Repositories documentation.

   • To create a new repository or add an existing repository to the list of cPanel-managed repositories, set the Clone a Repository toggle to disabled.

     • This URL cannot contain a username-and-password pair.
     • This URL must include the http://, https://, ssh://, or git:// protocols or use the user@example.com/path format, where user represents the username, example.com represents the domain, and path represents the repository path.
     • You cannot enter a local repository path.
     • The system performs additional checks for clone URLs that use the ssh:// protocol. For more information, read the SSH host key verification section below.
       

3. In the Repository Path text box, enter the path to the directory that will contain the repository.
   

   • If the specified directory does not currently exist, the system will create it.
   • If the specified directory already contains a repository, the system will automatically add it to the list of cPanel-managed repositories.
   • This feature enforces several restrictions on repository paths. For more information, read the Repository path restrictions section below.
   • Unless you’re adding an existing repository to the list, the directory must be empty. Subdomain directories contain a cgi-bin directory and may also contain a .well-known directory. You must move these before you can create a repository.
     

4. In the Repository Name text box, enter the desired display name for the repository.

5. To immediately create another repository, select the Create Another checkbox.

6. Click Create, or click Return to Repository List to return to the list of repositories.

SSH host key verification

If you entered an SSH clone URL, when you click Create, the system will automatically check for the remote server’s public SSH host key. The system stores this key in the /home/user/.ssh/known_hosts file, where user represents your username.

Generate Key In Cpanel For Git Mac

• If the remote host is not registered with the system, click Save and Continue to add it to the file (register it). You can click Show Host Identification Information to view the host’s algorithm and SHA-256 and MD5 fingerprints.
• If the remote host is already registered, the system will create the repository.
• If the remote host’s public key has changed, the system will display a warning.
  • For third-party remote hosts, check for announcements about public key updates. Most companies that host repositories make announcements about these changes.
  • For remote hosts that you control, consider whether recent events on your system have caused changes to the public key, or contact your system administrator.

The system also performs this check and will request verification of altered host keys when you change repository information or update the repository.

If you cannot verify the validity of a change, exercise caution, especially if your repository includes sensitive content. An altered SSH key may indicate a Man-in-the-Middle attack.

Repository path restrictions

This feature enforces several restrictions for repository paths.

The .git directory

Do not modify or delete a repository’s .git directory or its contents. Modifications to this data can irreparably break the repository.

The system globally denies public access to repositories’ .git directories.

Character restrictions

You cannot create, delete, or view repositories with paths that include whitespace or any of the following characters

cPanel-controlled directories

You cannot create, delete, or view repositories in the following directories:

• .cpanel
• .trash
• etc
• mail
• ssl
• tmp
• logs
• .cphorde
• spamassassin
• .htpasswds
• var
• cgi-bin
• .ssh
• perl5
• access-logs

Manage repositories

Click Manage to modify or deploy repositories. Click Basic Information to view repository information, or click Pull or Deploy to pull or deploy changes.

• Repository Path — The repository’s directory. Click to open the directory for the repository in cPanel’s File Manager interface (cPanel >> Home >> Files >> File Manager) in a new browser tab.

• Repository Name — The repository’s display name. To modify this name, enter the new name and click Update.

• Checked-Out Branch — The currently checked-out local branch. To check out a different branch, select the desired branch and click Update.

  • If you select a different branch, the system will automatically pull changes from the remote repository when it checks out that branch.
  • If the repository is a bare repository, the system will not display this information.

• Currently Checked-Out Branch — The currently checked-out local branch. Click to open the Gitweb interface in a new browser tab.

• HEAD Commit — This section of the interface displays information about the active branch’s HEAD commit (the most recent commit to the branch). If the repository does not include any commits for the current branch or is a bare repository, the system will not display any HEAD Commit information. Click History to open the Gitweb interface in a new browser tab.

  • Commit — The SHA-1 value for the HEAD commit.
  • Author — The HEAD commit’s author.
  • Date — The date of the HEAD commit.
  • The commit message for the HEAD commit.
  • Remote URL — The URL of the repository’s remote repository.
  • Clone URL — The URL to use to clone the repository to another location (for example, your local computer, another cPanel account, or a GitHub account). Click Copy to copy this URL to your clipboard.

• Repository Path — The repository’s directory. Click to open the directory for the repository in cPanel’s File Manager interface (cPanel >> Home >> Files >> File Manager) in a new browser tab.
  

• Repository Name — The repository’s display name. To modify this name, enter the new name and click Update.

• Currently Checked-Out Branch — The currently checked-out local branch. Click to open the Gitweb interface in a new browser tab.

• Last Deployment Information — This section of the interface displays the following information about the most recent deployment of the repository:

  • Last Deployed on — The date of the deployment.
  • Last Deployed SHA — The SHA-1 value for the deployed commit.
  • Author — The deployed commit’s author.
  • Date — The date of the deployed commit.
  • The commit message for the deployed commit.

• Update from Remote — Click to pull changes from the remote repository and apply them to the cPanel-managed copy of the repository. The system pulls changes with the --ff-only option and will only succeed if the branch’s HEAD commit is up-to-date or Git can fast forward it.

• Remote URL — The URL of the repository’s remote repository.

• Deploy HEAD Commit — Click to deploy changes from the cPanel-managed repository. Deployment requires a .cpanel.yml file and at least one local or remote branch.

  • The system runs the tasks that you configure in the .cpanel.yml file in order to deploy the repository.
  • We strongly recommend that you check the .cpanel.yml file in to your remote repository and not the cPanel-managed repository.
  • The system cannot deploy changes for repositories with dirty working trees.

For more information about deployment, read our Guide to Git - Deployment and Guide to Git - How to Set Up Deployment documentation.
