What is SSL?
Secure Sockets Layer, or SSL, is a powerful encryption protocol designed to secure the connection between a website’s server and a user’s browser. It plays a pivotal role in protecting sensitive data such as credit card numbers, login credentials, and personal information from interception by malicious parties.
The primary function of SSL is to provide a secure channel for transmitting information across the internet. When an SSL certificate is installed on a website, it activates a padlock and the HTTPS protocol, indicating to users that the site is secure and their data is protected.
How Does SSL Work?
Understanding the mechanism of SSL might seem complex, but it can be broken down into simpler terms. SSL works by using a pair of keys – a public key used for encryption and a private key for decryption.
When a user accesses an SSL-secured website, a process called an SSL handshake is initiated. This is a series of back-and-forth communications between the user’s browser and the website server.
The steps of an SSL handshake are as follows:
- The browser requests the server to identify itself.
- The server sends a copy of its SSL certificate, including the public key.
- The browser checks the certificate’s validity with the certificate authority and then creates, encrypts, and sends back a symmetric session key using the server’s public key.
- The server decrypts the session key using its private key and sends an acknowledgement encrypted with the session key to start the encrypted session.
- The server and browser now encrypt all transmitted data with the session key.
This process ensures that each session has a unique session key, making it incredibly difficult for any potential eavesdropper to decrypt the data.

Importance of SSL
The paramount importance of SSL (Secure Socket Layer) lies in the security it provides to online interactions. It serves as an integral shield against cyber threats, safeguarding data integrity by encrypting the information transmitted between web servers and browsers. Without SSL, sensitive information such as credit card numbers, passwords, and personal data can be intercepted and exploited by malicious parties.
This encryption technology ensures the confidentiality of the data exchanged by transforming it into an undecipherable format that can only be accessed with a unique key. In the unfortunate event of data interception, the encrypted data remains unintelligible to the unauthorized party. By providing this secure data transmission, SSL significantly minimizes the risk of data breaches and cyber-attacks.
Another indispensable aspect of SSL is its contribution to a website’s SEO (Search Engine Optimization) performance. Google, the most prolific search engine, acknowledges the importance of SSL encryption by making it an essential factor in their ranking algorithm. Websites equipped with SSL certificates are more likely to attain higher search rankings, boosting their visibility and accessibility to prospective visitors.
Apart from encouraging increased organic traffic, SSL also plays a pivotal role in Google’s indexing system. Google’s indexing bots often prioritize secure pages, which means SSL-encrypted websites stand a better chance of being crawled and indexed faster. This factor, in turn, accelerates the SEO efforts by granting a competitive edge in the digital landscape.
Trust and Credibility
Hinging on the security and SEO benefits, SSL also bolsters the trust and credibility of a website. Users often look for visual cues such as a padlock icon or ‘https’ in the URL to verify the website’s security. SSL certificates provide these signs, reinforcing the trust factor and fostering a sense of security among the users.
Moreover, an SSL certificate also displays the website’s information, including the name of the certificate holder and the issuing authority, which further validates its credibility. This transparency not only encourages user engagement but also enhances the likelihood of transactions, making SSL essential for e-commerce and any website that handles sensitive user data.
In conclusion, the importance of SSL lies in its tri-fold benefits: security, SEO advantage, and the establishment of trust and credibility. Irrespective of the ssl certificate cost, the advantages it offers validate the investment, making it an essential asset for every website owner.
Types of SSL Certificates
In the digital world where data security is paramount, SSL certificates play a crucial role in ensuring the safety of online data transfer. There are primarily three types of SSL certificates available, each catering to a different level of security requirement. These are Domain Validation (DV) SSL, Organization Validation (OV) SSL, and Extended Validation (EV) SSL.
Domain Validation (DV) SSL
The Domain Validation, or DV SSL, is the most fundamental type of SSL certificate. It is primarily utilized to verify the domain ownership of the website. The Certificate Authority (CA) checks the right of the applicant to use a specific domain name. This process is generally automated and can be completed quickly, often within a few minutes. However, it’s worth noting that while DV SSL does provide a basic level of encryption, it does not validate the organization behind the website. Hence, it’s most suitable for websites that do not deal with sensitive information.
Organization Validation (OV) SSL
The Organization Validation, or OV SSL, offers a higher level of security compared to DV SSL. Besides domain ownership, the CA also verifies the organization’s existence and legitimacy by checking details such as business name, location, and legal existence. This process can take a few days to complete. Websites with OV SSL certificates provide visitors with more confidence about the site’s authenticity, making it a preferred choice for business websites.
Extended Validation (EV) SSL
The Extended Validation, or EV SSL, is the most advanced and secure type of SSL certificate. The EV SSL requires a thorough and rigorous validation process by the CA. This includes verifying the legal, physical, and operational existence of the entity, as well as the rights to use the domain name. The process of obtaining an EV SSL certificate can be time-consuming and may require several weeks to complete. However, the higher level of trust it offers to website visitors makes it an excellent choice for e-commerce sites and other platforms handling sensitive user data.
To better understand the differences among these SSL certificates, here’s a simple comparison table:

It’s a common misconception that an SSL Certificate negatively impacts website performance. On the contrary, SSL can actually enhance your site’s performance, especially with HTTP/2. HTTP/2 is the latest update of the HTTP protocol and uses SSL as a standard. It was designed to decrease latency and improve speed by enabling high performance features like multiplexing, header compression, and Server Push.
However, the impact of SSL on your website’s performance primarily depends on your server’s configuration and the SSL Certificate type. Implementing SSL does require extra processing power for the encryption and decryption of data. Yet, with today’s powerful servers and optimized software, this additional load is negligible and often compensated by the benefits of HTTP/2.
How to Check if a Website has SSL
Verifying whether a website possesses an SSL Certificate is straightforward. When you navigate to a website, inspect the URL in the address bar. A secured website with an SSL Certificate will have a URL beginning with “https://”, with the “s” denoting “secure”.
In addition to the “https://” prefix, most modern browsers display a padlock icon before the URL. By clicking on this padlock, you can view details about the SSL Certificate, including the issuing Certificate Authority and the certificate’s validity period.
Here’s a step-by-step guide on how to check if a website has SSL:
- Open the website you want to check.
- Look at the URL in the address bar. If it begins with “https://”, the website has an SSL Certificate.
- For more details, click on the padlock icon (if present) next to the URL.
- A window will pop up, providing more information about the website’s security.
Remember, the presence of SSL is a crucial indicator of a website’s commitment to security. While an SSL Certificate doesn’t guarantee complete security, it does significantly boost the website’s credibility and user trust.
