HTTPS is an extension of HTTP and serves to enhance security. The application of HTTPS in Dynamic Route for CDN (DCDN) secures content transmission. This provides a secure and efficient method of browsing data when clients have fast access to website content. This topic describes how to validate and configure different types of HTTPS certificates.
HTTPS certificate files must be in the Privacy Enhanced Mail (PEM) format. For more information about how to convert certificate files from various formats to the PEM format, see Certificate formats.
The HTTPS feature is a value-added service. After you enable HTTPS, you are billed for the service based on the number of HTTPS requests that DCDN has received. You cannot use DCDN resource packages to deduct the charges of the service. For more information about HTTPS pricing, see Requests billing.
- A domain validated (DV) certificate has a safety lock. It only verifies the ownership of a domain name. A DV certificate verifies the ownership of a domain name by verifying the specified file of the domain name or the TXT record of the domain name.
- An organization validated (OV) certificate is a standard SSL certificate that verifies the identity of an organization. An OV certificate provides more trust than a DV certificate, but the validation process is stricter and longer. OV certificates are typically used in the e-commerce, education, and gaming sectors.
- An extended validation (EV) certificate follows the guidelines that are maintained by the Certification Authority Browser Forum, also known as the CA/Browser Forum. EV certificates are SSL certificates of the highest security level. Each EV certificate is identified by an object identifier (OID). Each OID indicates a complete enterprise name. EV certificates are widely used in sectors such as financial transactions and online banking.
