1. Be sure to deploy SSL certificates that support all browsers, and never use self-signed certificates to save money! That is to say, the browser can recognize that the SSL certificate has been deployed on the website without installing any root certificate on the user's computer, which is the minimum requirement for deploying SSL certificates, because it is impossible for a website to require all users to install a specific root certificate, and IE7 browser will directly intercept SSL certificates that do not support browsers when users visit, so SSL certificates cannot be deployed.

2. Choose the appropriate SSL certificate according to your own business needs (provided that it supports the SSL certificate of the browser), because there are many brands to choose from in the market at present. Of course, domestic brands that support the browser are preferred, which is not only cost-effective, but also fully supports Chinese and local technical support and after-sales service.

3. In terms of product functions, SSL certificates supporting SGC mandatory 128-bit encryption are preferred. Only in this way can we ensure that users can use various versions of browsers to achieve high-strength encryption of 128 bits, because 40-bit and 56-bit encryption is no longer secure; Secondly, if all users use a browser that supports 128-bit encryption, the website can purchase an SSL certificate to verify the identity of the entity and display the company name in the certificate, which will be cheaper. Finally, if the website is very price-sensitive, consider deploying an SSL certificate that only verifies the domain name ownership, and the company name is not displayed in this certificate.

4. If multiple sites with different domain names are deployed on one server, it is recommended to purchase SSL multi-domain certificates;

5 .. For e-commerce websites, it is recommended to adopt EV SSL or OV SSL certificates. Especially recommend EV

SSL certificate. This certificate can turn the address bar of new browsers such as IE7 and Firefox 3 into green, and clearly tell website visitors that the identity of this website has been strictly verified by global unified standards and is credible. Green address bar means green security channel, which can enhance customer trust and promote more online sales.
