There are a few different ways to check a site certificate. One way is to look for the padlock icon in the address bar of the browser. If the padlock icon is present, it means that the website has a valid SSL certificate. Another way to check a site certificate is to click on the padlock icon and then click on the “Certificate” tab.

1. Validity

The validity of a site certificate is an important factor to consider when checking a site certificate. A valid certificate indicates that the certificate has been issued by a trusted certificate authority and that the website has been verified as legitimate. An expired certificate, on the other hand, indicates that the certificate is no longer valid and that the website may not be safe to visit.

There are a few different ways to check the validity of a site certificate. One way is to look for the padlock icon in the address bar of the browser. If the padlock icon is present and green, it means that the website has a valid SSL certificate. Another way to check the validity of a site certificate is to click on the padlock icon and then click on the “Certificate” tab. This will display the details of the SSL certificate, including the issuer, the validity period, and the subject.

It is important to note that the validity of a site certificate is only one factor to consider when checking a site certificate. Other factors to consider include the issuer and the subject of the certificate. However, the validity of a site certificate is an important indicator of the legitimacy of a website.

2. Issuer

The issuer of a site certificate is the organization that has verified the identity of the website and issued the certificate. When checking a site certificate, it is important to consider the issuer of the certificate. A certificate issued by a trusted certificate authority (CA) is more likely to be valid and legitimate than a certificate issued by an unknown or untrusted CA.

Role of the Issuer

CAs play a vital role in the security of the internet. They verify the identity of websites and issue certificates that vouch for the legitimacy of those websites. This helps to protect users from phishing attacks and other online scams.
Types of Issuers

There are many different types of CAs, ranging from large, well-known organizations to small, private companies. Some CAs specialize in issuing certificates for specific types of websites, such as e-commerce websites or government websites.
Trust and Reputation

The trust and reputation of a CA is an important factor to consider when checking a site certificate. A certificate issued by a trusted CA is more likely to be accepted by browsers and other applications. This is because trusted CAs have a track record of issuing valid and legitimate certificates.
Checking the Issuer

You can check the issuer of a site certificate by clicking on the padlock icon in the address bar of your browser. This will display the details of the SSL certificate, including the issuer, the validity period, and the subject.

By understanding the role of the issuer and how to check the issuer of a site certificate, you can help to ensure that the websites you visit are legitimate and that your personal information is safe.

3. Subject

In the context of “how to check site certificate,” the “Subject” refers to the domain name or hostname that the certificate is issued for. It is an essential component of a site certificate as it specifies the website or online service that the certificate is intended to secure. Without a valid “Subject” field, a site certificate cannot be considered valid and will not be trusted by browsers or other applications.

When checking a site certificate, it is important to verify that the “Subject” field matches the website or online service that you are visiting. This helps to ensure that the certificate is valid and that the website or online service is legitimate. If the “Subject” field does not match the website or online service that you are visiting, it is possible that the certificate is invalid or that the website or online service is not legitimate.

In addition to the practical importance of the “Subject” field when checking site certificates, there are also broader implications to consider. For example, the “Subject” field can be used to identify the owner or operator of a website or online service. This information can be useful for law enforcement or other investigations. Additionally, the “Subject” field can be used to track the issuance and expiration of site certificates, which can help to ensure that certificates are not used after they have expired.
