We created the SSL Certificate Checker so that you can gather all the information about the SSL certificate of the host or domain being checked. You can use the tool to check the validity of SSL and the date of issue, expiration date. We will tell you more about it below.
What is an SSL
You’ve probably noticed that you share your personal information with the website while you’re online. Many activities on sites require different data: from your email address to your payment cards. How do you protect your data from intruders? SSL certificate comes to the rescue. It is a technology that will protect confidential information during the use of the site by the readers.
SSL (Secure Sockets Layer) is a unique digital signature for your resource. It means that the site has a security certificate installed. It means that users’ data is reliably protected. You may come across a green, gold, or gray lock in the address on some sites.
SSL also proves that the domain belongs to a real company. What does this certificate contain?
- the domain name for which it was generated;
- the legal entity that has rights to it;
- the physical location of the site owner;
- information about the expiration date.
An SSL certificate guarantees the encryption of the connection between the user and the site. Simply put the data shared by users are fully protected by the certificate from access by any unauthorized parties.
How does an SSL Certificate Work?
- The user enters a domain name in the browser.
- The server sends the SSL certificate and public key data.
- The browser verifies the data, generates a session problem, encrypts it, and sends it back.
- The server decrypts the key.
- A secure connection for the session is established.
- User data is now protected.
How to use an SSL certificate? Everything ensues automatically. When users perform a transaction, they enter much of their bank card details. After the transaction is processed, the information is sent to your server. At this point, the personal data is vulnerable, and attackers can take advantage of the situation for their illicit purposes. The browser encrypts the information. The data can only be decrypted using a key stored on the server. Even if hackers can gain access, they won’t decrypt it.

Types of SSL Certificates
When choosing one of the common types of security certificates for your resource, you should consider the peculiarities of the site and its scale. For your convenience, we have divided further information into many categories. Learn the best tips for each type of website.
Sites for individuals
Small internet projects can use an encryption cert with hostname validation. It is useful if users create accounts, subscribe to news, pay for services. Certificate registration will take no more than 10 minutes, and you do not need any additional documents.
Small and medium business projects
Social networks and online stores can install SSL certificates with corporate validation. Such certificates are issued for legal entities. Use this type of certificate if your users store their information on your site. Also, this certificate is useful if users perform transactions. It takes up to three days to install such a certificate.
Large commercial projects
Government and health organizations, large online stores, banks, and investment funds must use SSL certificates with advanced verification. Because users store money, securities, bank card data, and personal papers, a high level of security are required.
Only legal entities receive such certificates, and it’s not an easy process. To be issued such a certificate, you have to provide information such as domain name, company registration, contact information, and the right to conduct business for verification by the support service. The process usually takes no more than ten business days. These sites get a green badge with the company name in the domain area. It indicates that the company is trustworthy and that the site belongs to that company.
Multiple domains
A multidomain security certificate is a good solution for a corporate website, mail server, or other internal resources. Such a certificate comes in handy for companies that have multiple domains. There are three types of multidomain security certificates – domain validated, organization validated, or green string.
Subdomains
Those with a multipage corporate web site, online store, or trade chaining network should consider getting an SSL certificate for Wildcard domains. This type of certificate is designed for those who want to protect the main domain or all subdomains at once.
Importance of SSL Certificate Checker Using
SSL certificates are important for any website today. They tell your browser how trustworthy each site you interact with is. They also confirm that there is an encrypted connection. Using our SSL Certificate analyzer tool, you can check for a security certificate for any site you are interested in.
An SSL certificate shows that a reputable third party has verified that the site is trustworthy. If, however, you find a site without SSL security during the SSL Certificate Checker, it means that its owner has not disclosed any information. That means that such a site is potentially dangerous for your data.
If users’ data is stolen due to a data leak, attackers can use it to steal or sell data online. An SSL security certificate does a good job of preventing unwanted access to your data if it is leaked. Keep in mind that encryption is impossible to break without a private key.
Use extra measures to encrypt your entire Internet connection. It will ensure that all your online activities are encrypted. Although sites with SSL security certificates help keep users’ data safe, they can only protect connections to individual sites.
Checking the validity of SSL is good but not enough to optimize your site for search engines!

How an SSL Certificate affects SEO?
When it comes to how a security certificate impacts your site’s position in search engines, the installation of an HTTPS connection has been a ranking factor for almost a decade now. Google has openly stated that sites that use an SSL certificate will receive higher rankings.
Remember that switching your site to HTTPS will not help bring your site to the first positions in search engines. Only comprehensive work will help you get good search engine rankings. Work on other ranking factors and optimize your site for them to achieve higher positions.
However, not all sites are in a hurry to install SSL certificates. Switching to HTTPS protocol can be a challenge for large websites. Besides, after installing SSL certificates, check your website for mistakes like HTTPS page links to HTTP JavaScript, HTTPS page links to HTTP image, and HTTPS page links to HTTP CSS.
Why do I need an SSL certificate?
The principle of SSL encryption?
- The public key encrypts the message. It is used when you want to send user information to internal servers.
- A private key decrypts the message when it is received from the browser. This key is stored on the site internal server and is not sent with the message.
- A session key helps encrypt and decrypt messages simultaneously. It is generated for a short period while the client is on the site (that is, an active session of interaction with the site lasts). Once the tab is closed, the session is over. It means that the key stops working.
