How to Generate Public and Private Keys with cPanel

By | September 30, 2022

Assuming you have cPanel installed on your web server, generating both public and private keys is a simple process. First, log into cPanel and navigate to the “Security” section. From there, click on the “SSH/Shell Access” icon. On the next page, you will see an option to generate a new key pair. Select that option and follow the prompts. Once the key pair has been generated, you will be given the opportunity to download both the public and private keys. Be sure to download both!

Now that you have your keys, you can use them to authenticate with your server via SSH instead of using a password. This adds an extra layer of security, as it is now much more difficult for someone to gain unauthorized access to your server. To use your keys, simply copy the contents of the public key into the appropriate file on your server (usually ~/.ssh/authorized_keys) and then attempt to log in using your private key from your local computer. You should not be prompted for a password when doing so. If you are prompted for a password, double-check that you copied the public key correctly and try again.

Log in To cPanel Servers with SSH Keys

To log in to cPanel servers with SSH keys, you need to generate a public and private key pair. The private key will be kept on your local computer, while the public key will be uploaded to the cPanel server. Once the keys are set up, you can log in to the server without using a password. Generate a public and private key pair for SSH.ssh-keygen -t rsa -b 4096 -C “” the above should be run on your local computer, not the server.

Log to your Cpanel Account

To log in to your cPanel account, you will need your domain name, hosting account username and password. Enter these in the login fields at the top right of the page and click “Login.” If you have any problems logging in, please contact your hosting provider for assistance.

Search for SSH on the search box

If you’re looking for a secure way to access your computer or server, look no further than SSH. SSH, or Secure Shell, is a protocol that allows you to securely connect to a remote machine. SSH keys are used to authenticate the connection, and all data is encrypted, ensuring that your information is safe from prying eyes.

Authorizing the public key

A public key is a cryptographic key that can be used by anyone to encrypt a message or verify a digital signature. In order to be secure, the key must be kept secret by its owner.

SSH Keys: SSH Authentication with Public Key Cryptography

SSH uses public-key cryptography for authentication. A user creates a pair of keys (a public and private key) on their local computer and then uploads the public key to the server. To connect to the server, the user must use the private key, which is decrypting by the server using the public key. This process is known as SSH authentication.

Download your private key

To download your private key, you’ll need to enter your passphrase. This will allow you to access your key on your local computer. Once you’ve created the key, you can use it to decrypt your messages.

Add SSH Key by Command Line

To add an SSH key by command line, first generate a key pair using the ssh-keygen command. This will create a public and private key. Next, run the following command to save the public key:

$ ssh-copy-id -i ~/.ssh/ user@hostname

Enter your passphrase when prompted. This will copy your public key to the remote host. Finally, test your connection by running the ssh user@hostname command.

Disabling/Enable Password Authentication

If you want to disable password authentication for SSH on your server, you’ll need to generate a key pair and authenticate via SSH using that key pair. To do this, first create an SSH key using the ssh-keygen command. Then, edit the /etc/ssh/sshd_config file and change the PasswordAuthentication setting from yes to no. Finally, restart the SSH service to apply the changes.

Generate SSH Keys in Windows with PowerShell

In Windows, you can generate SSH keys with PowerShell. To do this, you need to open PowerShell and enter the following command: ssh-keygen. When prompted, press enter to create a new key pair. You will then be asked to enter a passphrase. This is optional, but if you choose to set one, make sure to remember it. Once the key pair has been generated, your public key will be saved in the ~/.ssh/ directory and your private key will be saved in ~/.ssh/id_rsa. You can view your public key by entering the command: cat ~/.ssh/ Your key fingerprint will be displayed, which you can use to verify your identity.

Generate SSH Keys in Windows with PuTTY

To generate SSH keys in Windows with PuTTY, first download and install PuTTY. Then, open the PuTTYgen program. In the “Key” section at the top of the window, select “RSA” from the drop-down menu. Enter a passphrase in the “Key passphrase” and “Confirm passphrase” fields. Next, click the “Generate” button. This will create a public and private key pair. The public key will be displayed in the text box labeled “Public key for pasting into OpenSSH authorized_keys file”. The private key will be saved to a directory of your choice. Finally, configure PuTTY to use your new SSH key pair by selecting it under the “Connection > SSH > Auth” category in PuTTY’s configuration window.

Generate SSH Keys in Unix or macOS Terminal

To generate SSH keys in Unix or macOS Terminal, you need to use the following command: ssh-keygen -t rsa. This will create a key pair, consisting of a public and private key. Press enter to accept the default location and file name for the key pair. Next, you will be prompted to enter a passphrase. This is optional, but if you choose to set one, make sure to remember it! Once you’ve entered your passphrase (or pressed enter if you’re not setting one), your public key will be saved. You should see a message saying “Your public key has been saved in [file name]”.

To view your public key, use the following command: cat ~/.ssh/ This will display your key fingerprint, which is a unique identifier for your key. You can use this fingerprint to verify that the key is valid.

To save your private key, use the following command: cp ~/.ssh/id_rsa [directory]. This will copy your private key to the specified directory. Make sure to keep this key safe and secure!

How to SSH your cPanel account (from Windows PC)

To SSH your cPanel account from a Windows PC, you will need to follow these steps:

1. Download and install an SSH client. We recommend PuTTY.

2. Launch the PuTTY client and enter your cPanel account’s IP address in the Host Name field. Leave the Port field as 22.

3. Under the Connection category, expand the SSH menu and select Auth.

4. Click Browse and locate your private key file (.ppk).

5. Click Open to return to the Session category. Then, click Open at the bottom of the PuTTY configuration window to connect to your cPanel account using SSH.

6. When prompted, enter your cPanel username and password. You will be logged in to your hosting account!

Do SSH keys need passwords?

No, SSH keys do not need passwords. They are used to authenticate a user without the need for a password.

Can I have a SSH key without an passphrase?

Yes, you can generate a SSH key without a passphrase. This is not recommended, however, as it means that anyone who gains access to your key will also have access to your account.
