If you own a website or run an online business, you may have heard of SSL certificates and wondered what they are and why you need them. Secure Sockets Layer (SSL) certificates are digital certificates that authenticate a website’s identity and enable an encrypted connection between a web server and a web browser. Companies and organizations need to add SSL certificates to their websites to secure online transactions, protect customer data, and gain user trust. In this article, I will explain what an SSL certificate is, how it works, what types of SSL certificates exist, and how you can add one to your website.

An SSL certificate contains the following information:

• The domain name that the certificate was issued for
• The person, organization, or device that it was issued to
• The certificate authority that issued it
• The certificate authority’s digital signature
• Associated subdomains
• Issue date of the certificate
• Expiration date of the certificate
• The public key (the private key is kept secret

Why SSL Certificate is Important for Your Website?

An SSL certificate is essential for any website that collects or transmits sensitive data. Here are some reasons why an SSL certificate is important for your website:

Encryption: SSL certificates encrypt data transmitted between the website and its users, making it impossible for hackers to intercept and read the data.

Authentication: An SSL certificate provides authentication by verifying the identity of the website owner. This ensures that users are communicating with the intended website and not an impostor.

Trust: An SSL certificate provides users with a sense of trust and confidence in the website. Users are more likely to trust a website that displays a padlock icon in the address bar, indicating that the website is secure.

SEO: Google has indicated that SSL certificates are a factor in its search ranking algorithm. Websites that have an SSL certificate are more likely to rank higher in search results than those that do not.

There are three types of SSL certificates: domain validated (DV), organization validated (OV), and extended validation (EV). Each type provides a different level of validation, and their issuance criteria vary accordingly.

Domain Validated (DV) SSL Certificate

A domain validated SSL certificate is the most basic type of SSL certificate. This type of certificate verifies only the domain ownership of the website, and the certificate authority (CA) issues it based on the domain name registration records.

DV SSL certificates are issued quickly and at a low cost, making them an excellent choice for small and personal websites. However, they provide minimal security, and visitors cannot validate the identity of the website owners.

To add a DV SSL certificate to your website, you can follow these steps:

Step 1: Choose a reputable SSL provider and purchase a DV SSL certificate.

Step 2: Generate a Certificate Signing Request (CSR) from your web hosting control panel.

Step 3: Submit the CSR to the SSL provider and complete the validation process.

Step 4: Once the validation is complete, the SSL provider will send you the SSL certificate files. Install the certificate on your web server.

Organization Validated (OV) SSL Certificate

An organization validated SSL certificate provides a higher level of validation than a DV SSL certificate. This type of certificate verifies both the domain ownership and the organization’s identity that owns the website.

To issue an OV SSL certificate, the certificate authority verifies the organization’s legal and operational existence, as well as its physical address and phone number. OV SSL certificates display the organization’s name in the SSL certificate, providing visitors with increased trust and assurance.

To add an OV SSL certificate to your website, follow these steps:

Step 1: Choose a reputable SSL provider and purchase an OV SSL certificate.

Step 2: Generate a Certificate Signing Request (CSR) from your web hosting control panel.

Step 3: Submit the CSR and required documents to the SSL provider to verify your organization’s identity.

Step 4: Once the validation is complete, the SSL provider will send you the SSL certificate files. Install the certificate on your web server.

Extended Validation (EV) SSL Certificate

An extended validation SSL certificate provides the highest level of validation and security. This type of certificate verifies the domain ownership, organization’s identity, and the legal and physical existence of the organization that owns the website.

EV SSL certificates require extensive verification checks, and the certificate authority issues them only to legitimate and established organizations. EV SSL certificates display the organization’s name and country in the web browser address bar, providing visitors with the highest level of trust and assurance.

To add an EV SSL certificate to your website, follow these steps:

Step 1: Choose a reputable SSL provider and purchase an EV SSL certificate.

Step 2: Generate a Certificate Signing Request (CSR) from your web hosting control panel.

Step 3: Submit the CSR and required documents to the SSL provider to verify your organization’s identity.

Step 4: Once the validation is complete, the SSL provider will send you the SSL certificate files. Install the certificate on your web server.

Step 5: Test your website with SSL certificate installation checker tools to ensure it is installed correctly and working properly.

How to choose a Good CA for your website:

Choosing a good CA for your website is an important decision that can affect your website’s security, trustworthiness, and performance. Here are some factors to consider when choosing a CA:

Reputation: You want to choose a CA that is well-known and trusted by browsers, users, and other websites. A reputable CA will have a strong track record of issuing valid certificates, following industry standards and best practices, and providing reliable customer support. You can check the reputation of a CA by looking at online reviews, ratings, testimonials, awards, and accreditations.

Validation: You want to choose a CA that offers the type of validation that suits your website’s needs and goals. As mentioned earlier, there are different levels of validation depending on how much information the CA verifies about your website’s identity. DV certificates are the easiest and cheapest to obtain but provide the least amount of trust indicators. OV certificates require some organization details but provide more credibility. EV certificates require the most rigorous verification but provide the highest level of trust indicators such as displaying company name in green in some browsers’ address bars.

Price: You want to choose a CA that offers competitive pricing for its certificates without compromising on quality or service. The price of an SSL certificate can vary depending on the type of validation, the number of domains or subdomains covered, the length of validity (usually one or two years), and any additional features or benefits offered by the CA such as warranty, malware scanning, site seal etc. You can compare prices from different CAs online or look for discounts or coupons.

Support: You want to choose a CA that provides responsive and helpful support for its customers before, during, and after issuing an SSL certificate. A good CA will have multiple channels of communication such as phone, email, chat etc., and will be available 24/7 to answer your questions or resolve any issues you may encounter with your certificate. You can test the support quality of a CA by contacting them with some queries before buying a certificate.

Some examples of popular and reputable CAs are DigiCert, Let’s Encrypt, GoDaddy, Comodo etc. You can also use tools like SSL Shopper or SSL Labs to compare different CAs based on various criteria such as price, validation level, browser compatibility, customer reviews etc.
