What Is an SSL Certificate?

An SSL certificate, short for Secure Sockets Layer certificate, is a digital certificate that authenticates the identity of a website and enables secure encryption of data transmitted between the web server and the browser.

When a user visits a website secured with an SSL certificate, a visual cue such as a padlock icon or ‘https://’ displayed in the address bar indicates a secure connection. The encryption process involves scrambling the data using complex algorithms, making it unreadable to anyone intercepting it en route. This ensures that sensitive information like login credentials, payment details, and personal data remain confidential and protected from cyber threats.

What Are the Different Types of SSL Certificates?

TLS/SSL certificates come in three types: Domain Validated (DV), Organization Validated (OV), and Extended Validation (EV). These certificates vary in the level of identity checks they require and provide protection for brands, businesses, and e-commerce stores.

Domain Validated (DV) SSL Certificates

Minimum security check.

These provide basic encryption and validation by verifying the domain ownership, offering a cost-effective solution for securing websites with essential protection.

DV SSL certificates are ideal for small businesses and personal websites that do not handle sensitive information requiring extensive validation processes.

These certificates are issued quickly as they primarily focus on verifying domain ownership through automated email or DNS verification methods.

Although DV SSL certificates offer a lower level of security compared to Extended Validation (EV) or Organization Validated (OV) certificates, they still provide crucial encryption for data transmission, safeguarding user information from unauthorized access.

Organization Validated (OV) SSL Certificates

Additional security and validation checks.

OV SSL authenticates both the domain ownership and the organization’s identity, providing enhanced security and trust for online businesses and users.

When a business opts for an OV SSL certificate, a Certificate Authority (CA) conducts a thorough vetting process.

This process involves verifying the legal existence of the organization, confirming its operational status, and validating the domain ownership.

Users are more likely to trust websites that display the padlock symbol and ‘https://’ in the address bar, indicating secure and encrypted connections.

Extended Validation (EV) SSL Certificates

Highest level of authentication, validation, and security checks.

Extended Validation (EV) SSL certificates offer the highest level of validation, displaying the organization name in the browser address bar and instilling maximum user trust through stringent verification processes.

Businesses that opt for EV SSL certificates demonstrate their commitment to security and credibility. These certificates provide a visible assurance of authenticity to website visitors, increasing confidence in the organization and reducing the risk of phishing attacks.

The rigorous validation requirements for EV certificates involve verifying the legal existence, physical location, and operational status of the entity. This meticulous validation process sets EV certificates apart from other types of SSL certificates, making them a preferred choice for e-commerce sites, financial institutions, and any website that values trust and security.

How Do You Obtain an SSL Certificate?

Obtaining an SSL certificate, in most cases, can be done directly from within your hosting or server provider (IONONS, Siteground, WPX etc.). But, you could also grab one from a trusted Certificate Authority (CA).

Purchase from a Certificate Authority (CA)

Purchasing an SSL certificate from a reputable Certificate Authority (CA) ensures industry-standard security features and validation processes, essential for establishing secure connections on websites.

SSL certificates issued by trusted CAs encrypt data transmitted between servers and users, safeguarding sensitive information such as login credentials, payment details, and personal data.

They provide visitors with visual cues like padlocks and https in the URL, instilling trust and confidence in the site’s legitimacy.

These certificates adhere to stringent security protocols and are recognized by leading web browsers, ensuring compatibility and seamless browsing experiences for users.

Get a Free SSL Certificate from a Web Hosting Provider

Some web hosting providers offer free SSL certificates as part of their hosting packages, simplifying the installation process and addressing potential challenges associated with SSL integration.

The free SSL certificate you are looking for is Let’s Encrypt and can most of the time be easily selected within your Domain tab of your hosting control panel.

These SSL certificates are especially useful for website owners who want to provide a secure browsing experience for their visitors without incurring additional costs. By offering free SSL certificates, hosting providers enable websites to encrypt data transmissions, protect user privacy, and improve trustworthiness.

Most hosting providers will also include paid SSL certificate options so that you can adhere to the highest levels of security and trustworthiness directly from your cPanel without having to mess around with installing it yourself.

How Do You Install an SSL Certificate on Your Website?

Installing an SSL certificate on your website can be done manually by configuring server settings or by utilizing a web hosting provider’s SSL installation service for seamless integration of encryption protocols.

For those opting to go the manual route, the process involves generating a Certificate Signing Request (CSR) on the server, and then submitting it to a Certificate Authority (CA) for validation. Once the SSL certificate is issued, it needs to be installed on the server, along with private keys and intermediate certificates, to ensure secure connections. This method gives you more control over the setup and customization of the SSL configuration.

On the other hand, choosing a hosting provider’s SSL installation service simplifies the process significantly by offering automated installation through their control panel. This service is ideal for users looking for a hassle-free setup without the need for technical expertise. It’s important to ensure that the hosting provider follows best practices to guarantee the security and reliability of the SSL implementation.
