The encrypted https is more secure than http. However, strictly speaking, data cannot be protected unless the communication partner is genuine.
Therefore, there is a "certificate (SSL server certificate)" as a means to verify the other party of communication. An SSL server certificate is a certificate used during SSL encrypted communication. It is a type of electronic certificate and acts like a seal certificate for the server.
The certificate authority issues a certificate legal leads for sale by linking the public key (encryption key) used to encrypt SSL/TLS communications with the common name (FQDN) and domain owner information. The issued SSL server certificate is then installed on the web server or mail server.
SSL stands for "Secure Sockets Layer," and an SSL server certificate is a digital certificate that enables websites to communicate securely. SSL server certificates are issued by trusted organizations called Certificate Authorities (CAs), and certify that a site is trustworthy and encrypt data communication between users and servers.
How to check SSL server certificate
There are three types of SSL server certificates: "Domain Validation", "Corporate Validation" and "EV Validation". All of them can be easily checked. Here we will introduce how to check domain validation, so please check it on the websites you usually visit.
*Checking method for Windows/Chrome
Click the button in the top left corner of your browser .
The Certificate window appears.
If you select the "Subject" field from the "Details" tab in the "Certificate" window, you will see a string starting with "CV = " in the bottom box. This string is the domain name of your homepage.
How to tell if a site is trustworthy
We have explained how to check SSL server certificates, but recently even these certificates have been misused by cybercriminals. The "domain authentication" we mentioned earlier can be obtained free of charge by anyone who owns a domain, whether that person is a company or an individual.
The certificate is issued after verifying that you are the legitimate owner of the domain name, but does not carry out any further verification beyond sending an email to a contact email address, meaning that even cybercriminals can have a certificate if they own it.
We will introduce you to ways to determine whether a website is trustworthy, so please try the following in addition to checking the SSL server certificate.
