Beginner's Guide to SSL

Did you know that Google flags all websites that do not use SSL as "Not Secure"? This means that if you do not use an SSL certificate on your website, you will lose the trust of your customers. SSL certificates assist in protecting your website's data; they are actually required when receiving payments online.

What does SSL Stand For?

Netscape created the Secure Socket Layers (SSL) protocol, which has been in use ever since. It's a technique that encrypts and decrypts data between a user and a server so that no third party may access it.

SSL acts as a digital passport, verifying the identity of both you and the webserver you're connecting to. SSL establishes a secure connection through HTTPS once the identities of both parties have been verified. Certificates are used in this procedure. The information you enter into a form on an insecure website can be intercepted by a hacker when you submit it.

For example, an email address used to sign up for an offer could be included in this list of personal data that is collected. The term "man-in-the-middle attack" is commonly used by hackers to describe this type of "interception."

Inquiring minds want to know how attacks take place. Using this method is one of the most prevalent. A hacker infiltrates a server hosting a website and instals a little listening application that goes unnoticed. Whenever a visitor begins to enter information on a website, the malware will activate to capture the data and transmit it back to the hacker. However, using ETTVI's tool, the website's SSL certificate will be thoroughly analysed and checked, and its "security score" will be highlighted accordingly.

SSL Encryption Technique

A secure socket layer (SSL) is a type of encryption technique. It's a server-to-browser protocol that ensures data is secure. The server and browser are connected via an encrypted channel. SSL certificates should be used to safeguard websites that collect personal information from users, such as their e-mail address or credit card information. When a customer sees a padlock and https://, they can be assured that their personal information is safe and secure.

Types Of Certificates

A Certificate Authority (CA) is a piece of software created with the express purpose of processing and issuing certificates. SSL certificates are classified as domain number, encryption, and validity. The SSL website allows you to apply for each of the three classes. Validation and encryption certificates can be issued for domains, organisations, or even specific individuals or groups. Depending on the domain number, you can choose between single, multidomain, or wildcard certificate types for your certificates.

SSL Certificates with Extended Validation (EV)

The padlock, business name, HTTPS, and country are displayed in the address bar to avoid being mistaken for a spam website. An Extended Validation SSL is one of the most expensive SSLs to acquire, but it is essential for displaying the legitimacy of your site in the address bar. For an EV SSL, you must confirm that your domain is legitimately yours. For example, a credit card number is required for an online transaction, and this assures that you are lawfully gathering the data necessary to carry it out. Any firm may get an EV SSL certificate, and it should be a top priority for businesses with a large customer base. With the help of ETTVI's free online SSL checker, you may learn more about the SSL certificate that is currently placed on a specific domain.

Certifying an Organization's Validity (OV SSL)

This SSL certificate is required to ensure that your company and domain validation are authentic. It takes two steps to get an Organization Validated (OV) SSL certificate. To begin, the CA would check that the rightful holder owns the domain and that the organisation is really operating. Small green padlocks and corporate names would be displayed on the browser. If you can't afford an EV SSL certificate but still want to provide some level of encryption, then this is the certificate for you.

A Certificate of Domain Verification (DV)

A green padlock indicates a low level of encryption provided by the Domain Validation (DV) certificate in the address bar. Only a few company documents are required for this authentication, which is the fastest you can get. When adding a DNS to the CA, this is verified. In order to issue this certificate, the CA will verify that an applicant has the legal authority to submit a domain name for certification. In contrast to the EV SSL, the CA does not have a mechanism for verifying the identity of the recipient of your encrypted data. With that said, for those who can't afford the more expensive SSL, there is no better option than the default.

SSL Certificates with Wildcards

In the category of "domain and subdomain number," wildcard SSL certificates can be found. Using a wildcard SSL certificate allows you to utilise the same certificate for all of your subdomains. Using an wildcard, you might use it to access and the URLs. An alternative to purchasing many SSL certificates for a single number or domain is one like this.

SSL Certificate for Unified Communications (UCC)

SSL certificates that allow numerous domain names to reside on the same certificate are known as Unified Communications certificates (UCCs). Although they were first designed to connect a single server and browser, they have subsequently grown to include several domain names owned by the same person. In the address bar, a padlock shows the URL is authentic. An EV SSL certificate can also be considered if configured to display the padlock, green text, and country of origin. The only difference between this certificate and the previous one is the number of domain names linked with it.

Multi-domain SSL certificates can protect up to 100 domain names at once. The Subject Alternative Name (SAN) option allows you to make any necessary alterations to the names. A few instances of Multi-Domain names are com, mail, and etc.

SSL Certificate for a Single Domain

One domain is protected with a Single Domain SSL certificate. It is important to remember that this certificate cannot be used to secure subdomains or a whole other domain. ETTVI's SSL checker tool will thoroughly examine and check the website's SSL certificate, and it will then display a "security score" depending on how secure the website is. In order to get started, you must first decide on the type of certificate you require. If you host content on numerous platforms (on distinct domains/subdomains), you may require multiple SSL certificates.

For the vast majority of users, a regular SSL certificate will suffice. There are some industries that require special SSL certificate criteria, such as finance or insurance, so you should consult with your IT staff to be sure you're adhering to those standards. It is possible to get an SSL certificate for free or pay a monthly fee for a personalised certificate.

The validity duration of certification is also an important aspect. If you're seeking a longer-term solution, try purchasing a more advanced SSL certificate with a longer validity duration than the regular certificates.

Is Using SSL Beneficial for SEO?

Yes. Even though SSL's principal function is to protect visitors' personal information, it also has SEO benefits. In the eyes of Google, SSL is a ranking factor in the web search engine. Also, two websites with comparable information, but one with SSL enabled and the other not. It's possible that the first website's ranking will rise because it's encrypted. SSL is a clear SEO benefit; as a result, your website and all of its pages will rank higher.

ETTVI’s SSL certificate checker tool is to uncover issues with your SSL certificate's installation. With the help of a website certificate checking tool, you can assess whether or not the certificate for your web server has been appropriately installed and is valid.

Users of the Internet and SSL Certificates

Securing a website with an SSL certificate is essential. Furthermore, as online visitors become more technically informed, they are aware of the significance of an SSL certificate. It's not just Google Chrome's visual cues that are making a difference. Online visitors are no longer comfortable visiting a hazardous website because they understand the difference between an unsafe and a safe website.

What does SSL Protection Entail for Webmasters?

You can safely buy things or services from you online since websites speak with their customers to exchange data.

Adding an SSL certificate ensures a secure connection for these kinds of activities without becoming unduly technical. Everything that has to be secure online should be covered by an SSL certificate, which is the most crucial thing to remember.
