To set up SSH access using a key pair in cPanel, follow these steps:

1. Generate Key Pair in cPanel:

   • Log in to your cPanel account.
   • Navigate to Security > SSH/Shell Access.
   • Click on Generate Key and choose a name (default is id_dsa).
   • Create a strong passphrase if required, then click Generate Key.

2. Download Private Key:

   • After generating the key, download the private key file named id_rsa.
   • Save it securely on your local machine.

3. Convert Private Key to PuTTY Format:

   • Download and install PuTTY (e.g., puttygen.exe).
   • Open PuTTYGen and click File > Load Private Key.
   • Browse to select your id_rsa file, ensuring the All Files filter is active.
   • Enter your passphrase if required. If no passphrase is needed, leave fields empty.
   • Click Save Private Key, naming it as .ppk for later use.

4. Configure SSH Connection with .ppk File:

   • Open PuTTY and go to Connection > SSH > Auth.
   • Click Browse to select your saved .ppk file.
   • Return to the session settings, inputting the server IP and port (21098).
   • Click Open to connect.

5. Log in with Passphrase:

   • Upon connection, you'll be prompted for your login username and passphrase.
   • Enter these credentials to access your server via SSH.

6. Secure Your Keys:

   • Never share your private key (id_rsa or .ppk).
   • Keep backups of your keys in a secure location.
