Use cPanel → Security → SSL/TLS → Certificate Signing Requests (CSR) when a certificate authority requires a CSR.
- Open the CSR manager.
- Select or generate the appropriate private key.
- Enter the requested domain information.
- Complete the organization/contact fields required by the interface.
- Generate the CSR.
- Copy the encoded CSR exactly as produced for submission to the certificate authority.
Do not submit the private key with the CSR unless a specific secure certificate-management process explicitly requires it.
