What are the common questions before the purchase of SSL certificates?

SSL certificate may encounter some problems or doubts before purchase, such as whether installing a certificate on the server will affect the speed and traffic? Can network devices support SSL certificates? If the hardware and software (web server) certificate is changed, do I need to reapply? The managed server provider does not allow the configuration of ssl certificates? Let's take a look at the answers to these questions.

One: will the installation of a certificate on the server affect speed and traffic?

Of course, it will increase the processing burden on the server CPU, because you have to implement encryption and decryption for each SSL connection, but it generally doesn't have much impact. At the same time, it is recommended to pay attention to the following points to reduce the burden on the server:

(1) use SSL only for pages that need to be encrypted. Do not use https://, for all pages, especially the home page with traffic.

(2) try not to design large picture files and other large files on pages that use SSL, and try to use concise text pages.

If the number of visits to the website is very large, it is recommended to purchase another SSL acceleration card to specialize in SSL encryption and decryption, without any burden on the server at all. Or add additional servers.

Second: can network devices support SSL certificates?

The hardware manufacturing of the equipment can support certificates if the equipment supports the SSL protocol, and the general technical configuration documents are provided by these equipment manufacturers.

Third: if the hardware and software (web server) certificate is changed, do I need to reapply?

The server certificate is hardware independent. There will be no impact if the system and web server versions are the same. If the server software is changed, the certificate should be reapplied. The server certificate cannot be used by the replacement platform.

Fourth: the hosting server provider does not allow the configuration of ssl certificates?

Hosting servers are generally called virtual hosting providers. They configure multiple virtual sites on a better server. They generally provide ordinary 80 web services. If one of the sites is configured with certificates, the SSL protocol will load the entire server.
