Apply for a free certificate


You can only apply for a one-year free certificate of Class 1.




After the application is completed, import the PLF certificate to the server certificate in IIS manager at the same level as the "start page" machine-> function view->. Then, go to the web site under the website, instead of a virtual path. There is a "binding" in the right operation, and set certificate binding.

Virtual Path-functional view-SSL settings. Select "require SSL" to force the certificate.


 From the perspective of users, SSL certificates are divided into four types

Class1 (Domain Validation): only verifies the ownership of the domain name.
Class2 (personal validation): verifies the real identity of an individual in addition to the ownership of the domain name.
Class3 (Organization validation): verifies the identity of the operator, that is, Enterprise Authentication.
EV (extended verification): Some enterprise data verification except the identity of the operator.
For large e-commerce enterprises, class3 ev-level certificates are generally used to ensure the user's identity and gain the user's trust.

P.s. There are two types of certificates: common CA certificates and third-party certificates (EV certificates ). The general certificate has only one yellow lock in IE, And the EV certificate lock has text next to it. Which company has verified the domain name.

In IE7, opera 9.5, Firefox 3, and later browsers, the URL for installing the EV certificate is green in the address bar.

Color Description

Red indicates that the certificate has expired, is invalid, or has an error.

Yellow cannot verify the certificate or the identity of the certificate authority that issues the certificate. This may indicate a problem with the Certificate Authority's website.

The white certificate has been properly verified. This indicates that the communication between the browser and the website is encrypted. The Certificate Authority has not made any statement on the commercial conduct of the website.

Green this certificate uses extended verification. This indicates that the communication between the browser and the website is encrypted, and the certificate authority has confirmed that the website is owned or operated by an enterprise, the Enterprise is legally organized according to the permissions displayed on the certificate and security status bar. The Certificate Authority has not made any statement on the commercial conduct of the website.


If you try to use both secure (https/SSL) and insecure (HTTP) Web server connections to display elements, a prompt box will pop up in IE, And the chrom HTTPS will be warned with a red slash. In this case

Change the following to a relative path or Use https to connect directly. The dialog box is unfriendly.
