HTTP blocked by Google! Installation of SSL certificates is imminent!

Recently, Google announced that starting from July 2018, the address bar of the Chrome browser will mark all HTTP websites as unsafe websites. This move is a move by Google to improve the security of users online. By marking HTTP websites as unsafe websites, it encourages website owners to use the HTTPS protocol to provide more advanced security protection. In this context, Baidu platform issued an announcement that it will officially open the inclusion of HTTPS sites, which is also in response to Google's move to promote website owners to pay attention to website security and encourage them to switch to the HTTPS protocol.

SSL Certificate Analysis

An SSL certificate is a digital certificate used to establish a secure communication channel on the Internet. It is issued by an authoritative certificate authority (CA) to verify the identity and security of a website. The main function of an SSL certificate is to encrypt communications, ensure the security of data during transmission, and prevent data from being stolen or tampered with.

SSL certificates are mainly divided into the following categories:

Single-domain SSL certificate: protects the security of only one domain name, such as www.example.com or example.com.

Multi-domain SSL certificate: can protect the security of multiple domain names, such as example.com, http://www.example.com and mail.example.com.

Wildcard SSL Certificate: can protect a domain name and all its subdomains, such as example.com and its subdomains.

How to choose the corresponding SSL certificate

Choosing an SSL certificate should be based on the specific needs and circumstances of your website. Here are some considerations for choosing an SSL certificate:

Number of domain names: If you only have one domain name, you can choose a single-domain SSL certificate; if you have multiple domain names, you need to choose a multi-domain SSL certificate or a wildcard SSL certificate.

Security requirements: If your website has higher security requirements, such as involving sensitive information or online transactions, you need to choose a higher level SSL certificate, such as an EV SSL certificate.

Cost: The price of SSL certificates varies by brand, type, and security level, so you need to choose one based on your budget.

Compatibility: When choosing an SSL certificate, you need to consider its compatibility with various browsers and devices.

The Difference Between Free and Paid SSL Certificates

There are some differences between free and paid SSL certificates in terms of features and services. Here are the main differences:

Certificate Authority: Paid SSL certificates are usually issued by authoritative certificate authorities and have higher trust and recognition; free SSL certificates may be issued by less well-known organizations or individuals.

Security: Paid SSL certificates are more secure and usually provide more encryption algorithms and security protection measures; free SSL certificates may have some security loopholes and risks.

Technical support and services: Paid SSL certificates usually provide more comprehensive technical support and after-sales services; free SSL certificates may not have these services.

Usage restrictions: Paid SSL certificates have no usage restrictions or fewer restrictions; free SSL certificates may have some usage restrictions, such as only being used for testing or non-commercial purposes.

Based on the above analysis, the following are suggestions for different scenarios:

If your website has higher security requirements, such as involving sensitive information or online transactions, it is recommended to choose a paid EV SSL certificate to provide the highest level of security protection.

If your website has only one domain name, you can choose a free single-domain SSL certificate to save costs. However, you need to make sure that the certificate is issued by a trustworthy organization and confirm its security.

If your website has multiple domain names or needs to protect multiple subdomains, it is recommended to choose a paid multi-domain or wildcard SSL certificate to provide more comprehensive protection.
