Generating and adding an SSH key for secure authentication involves a few straightforward steps. Here\u2019s a guide to creating an SSH key, adding it to your local SSH agent, and configuring it for authentication with remote servers or services like GitHub, GitLab, etc.<\/p>\n\n\n\n

Generate the SSH Key<\/strong><\/p>\n\n\n\n

When prompted to \u201cEnter a file in which to save the key,\u201d provide a custom path within the htdocs<\/code> folder.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

step1: Open Git Bash and run the following:<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This command creates a new SSH key, using the provided email as a label.<\/p>\n\n\n\n

This saves the private key as project_name_ssh_key<\/code> and the public key as project_name_ssh_key.pub<\/code> in the htdocs<\/code> folder. When prompted to “Enter a passphrase,” type a secure passphrase or press Enter<\/strong> to skip.<\/p>\n\n\n\n

Step 2: Add the SSH Key to GitHub or a Server<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
    \n
  • Log in to GitHub and navigate to Settings > SSH and GPG keys<\/strong>.<\/li>\n\n\n\n
  • New SSH key<\/strong>, add a Title<\/strong>, paste the public key, and click Add SSH key<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    For a Remote Server:<\/strong><\/p>\n\n\n\n

    Copy the public key to the remote server’s ~\/.ssh\/authorized_keys<\/code> file.<\/p>\n\n\n\n

    ssh username@server_ip<\/code><\/pre>\n\n\n\n
    Append the key:<\/p>\n\n\n\n
    cat .\/project_name_ssh_key.pub | ssh username@server_ip \"mkdir -p ~\/.ssh && cat >> ~\/.ssh\/authorized_keys\"\n<\/code><\/pre>\n\n\n\n
    Test the SSH Key<\/strong><\/p>\n\n\n\n
    Test the connection to GitHub:<\/p>\n\n\n\n
    ssh -T git@github.com\n<\/code><\/pre>\n\n\n\n
    Test the connection to a remote server:<\/p>\n\n\n\n
    ssh -i .\/project_name_ssh_key username@server_ip\n<\/code><\/pre>\n\n\n\n
    Test the SSH Key<\/strong><\/p>\n\n\n\n
    Test the connection to GitHub:<\/p>\n\n\n\n
    ssh -T git@github.com\n<\/code><\/pre>\n\n\n\n
    Test the connection to a remote server:<\/p>\n\n\n\n
    ssh -i .\/project_name_ssh_key username@server_ip\n<\/code><\/pre>\n\n\n\n
    Configure Git to Use the SSH Key (Optional)<\/strong><\/p>\n\n\n\n
    If you’re using Git in the htdocs<\/code> folder and want it to use the generated SSH key:<\/p>\n\n\n\n
    Add the key to the SSH agent:<\/p>\n\n\n\n
    eval \"$(ssh-agent -s)\"\nssh-add .\/project_name_ssh_key<\/code><\/pre>\n\n\n\n
    Configure Git to use this SSH key:<\/p>\n\n\n\n
    git config core.ssh Command “ssh -i .\/project_name_ssh_key<\/p>\n","protected":false},"excerpt":{"rendered":"
