What is an SSL Certificate: Purpose, Types, and Installation

As an online store owner in Malaysia, the security of your online platform should be your main focus. 

In an era where cyber threats are on the rise, you will need to do everything possible to ensure that you protect your customers’ sensitive data. 

It is not just a security measure but a crucial business strategy. This comprehensive guide will provide you with all the information you need to know about SSL certificates and their role in the e-commerce security landscape.

What Is an SSL Certificate and How Does It Work

SSL (Secure Sockets Layer) certificates are digital passes that initiate data- encrypted connections between web browsers and web servers. This encryption ensures that the data transferred remains confidential and tamper-free. 

An SSL certificate is a security protocol and essentially serves as a protective envelope, shielding crucial confidential information like credit card numbers and login credentials from prying eyes. 

When a customer enters an SSL-secured website, the browser checks the SSL certificate’s validity. Upon verification, it creates an encrypted link, indicated by not only the padlock icon in the URL address bar of a browser but also by ‘https://’.

SSL certificates work by making public and private keys. One key of the pair (the public key) is known to the outside world, while the other (the private key) remains a secret only you know. Therefore, this visible assurance, also known as the public key, is your first line of defense and a sign of credibility for customers. 

Having your own private key is also for you to prevent criminals from impersonating you. It is important to remember that the HTTPS in the URL works to protect the communications between visitors and a web server from being intercepted by cyber attacks. 

SSL certificates are necessary for establishing this encrypted connection via an SSL connection usually referred to as an “SSL handshake”, in which the user’s web browser and the server establish a secure connection.

The Importance of SSL Certificates in E-commerce

In e-commerce, the stakes are high. This means that you cannot afford to make errors because a single breach can significantly tarnish your brand’s reputation. In that case, you need an SSL certificate to act as your storefront’s electronic security guard. 

There are several benefits of digital SSL certificates for your e-commerce store:

• Data Protection: SSL certificates render user data secure by preventing unauthorized parties from intercepting sensitive information and ensuring secure online transactions.
  
• Trust and Confidence: The presence of SSL reassures visitors that your site is secure. This fosters trust which is a currency in the realm of online shopping. A trust seal can further enhance this sentiment, affirming your site’s legitimacy to visitors and customers.
• Increased Security: SSL encryption ensures that data transmitted between internet users and your website remains private and protected by creating an SSL-encrypted session key each time they visit your site. It gives you the highest level of security you can ever need as an ecommerce website owner.
  
• Improved SEO: SSL is a ranking factor for search engines, helping your website to appear higher in search results and drive more organic traffic.
  
• Compliance with Regulations: SSL is a requirement for HTTPS websites that handle sensitive customer data, ensuring compliance with data protection laws.
  

Finally, when you implement SSL on your website this will not only boost user confidence and comfort but also can potentially drive higher engagement and conversions.

Types of SSL Certificates: Which One Is Right for Your Online Store?

There are various types of SSL certificates. In the following paragraphs, we will briefly discuss them as well as the validation levels for SSL vetting procedures. 

The types of SSL certificates are:

• Single domain SSL Certificates: As the name suggests, a single-domain standard SSL certificate applies to only one domain and cannot be used to authenticate any other domain.This means that it cannot even be used to authenticate subdomains of the domain it is issued for. However, it can secure all the pages on the domain it is issued for.
  
• Multi Domain SSL Certificates: A multi-domain certificate lists multiple domain names on one certificate so that domains that are not subdomains of each other can share a certificate. Essentially, they allow a single certificate to secure multiple domains, including subdomains of a single main domain name or entirely different domain names.
  
• Wildcard SSL Certificates: A Wildcard SSL certificate is issued for a single domain and all its subdomains. A subdomain falls under the umbrella of the main domain and a main domain can have multiple subdomains. For example, if your main domain is www.mydomain.com, your subdomains can be blog.mydomain.com, customersupport.mydomain.com, etc.
  
• Unified Communications Certificates: A UCC (Unified Communications Certificate) is a certificate capable of securing multiple domains and featured subdomains under a single certificate.
• TLS (Transport Layer Security) – A successor to SSL, TLS is similar to the SSL protocol, however, it addresses some security vulnerabilities of the former. A TLS certificate also supports more modern cryptographic algorithms and cipher suites.

A UCC is also known as SAN (Subject Alternative Name) as a user can add multiple names as the subject of the certificate.

Authentication and Validation Levels

The authentication and validation levels for SSL certificates can be broken down into the following categories:

• Domain Validated (DV) Certificates: Quick to obtain and cost-efficient, DV certificates are suitable for blogs or informational websites where online transactions aren’t performed.
  
• Organization Validated (OV) Certificates: These require more rigorous checks, as they validate the organization’s identity behind the domain. The OV SSL certificate is a good fit for business websites that handle more sensitive customer information.
  
• Extended Validation Certificate (EV): Extended validation certificates are the peak of web security. Offering the highest security level, an Extended Validation, EV, SSL certificate is ideal for large e-commerce sites demanding stringent authentication procedures. An EV-certified website has a green address bar.

Analyzing your business needs and budget will guide you to the appropriate SSL certificate.

How to Obtain an SSL Certificate for Your e-commerce Website: A Step-by-Step Guide

Obtaining an SSL certificate is a crucial step in ensuring the security and trustworthiness of your e-commerce business. 

This certificate encrypts the communication between your website and its visitors, protecting sensitive information such as personal data and payment details. 

In the following paragraphs, we will walk you through the process of obtaining an SSL certificate, providing you with a detailed understanding of each step involved.

1. Choose the Right Type of Certificate: It is essential to select the appropriate type of SSL certificate based on the nature and the scale of your e-commerce business. The options range from basic domain validation (DV) certificates to more advanced organization validation (OV) and extended validation (EV) certificates, which offer a higher level of validation and trust.
   
2. Select an SSL Certificate Provider: You’ll need a certificate authority’s digital signature. Take the time to research and choose a Certificate Authority (CA) you can trust as your SSL certificate provider. Look for providers with a strong industry reputation, positive reviews, and excellent customer support. This will ensure that you receive a reliable and trusted SSL certificate for your website.
   
3. Generate a CSR (Certificate Signing Request): To obtain an SSL certificate, create a Certificate Signing Request (CSR data file). It includes your public key, company information, and domain details so you can prove domain ownership. This request will be sent to the CA for validation and issuance of the SSL certificate. Follow the instructions provided by your web server or hosting provider to generate the CSR accurately.
   
4. Submit Your CSR to the CA: If you have generated the CSR to verify ownership, submit it to the selected CA along with any required validation documents. The certificate authority verifies the information provided and may require additional documentation to ensure the legitimacy of your business.
   
5. Install the SSL Certificate on Your Server: After the CA has validated your CSR and completed the issuance process, you will receive the SSL certificate. The Certificate is usually installed on a web server and you will need to follow the installation instructions provided by your web server or hosting provider to install the certificate correctly. This typically involves uploading the certificate files and updating your server configuration.
   
6. Verify the Installation: Once the SSL certificate is installed, perform a thorough verification to ensure that everything is working correctly. Test your website to ensure that it is accessible via ‘https://’ and that there are no security warnings or errors. Additionally, check for the presence of the padlock icon in the browser address bar, indicating a secure connection.

By following these steps, you can obtain a certificate-authority-issued SSL certificate for your e-commerce business, enhancing the security and trustworthiness of your website.

Remember to periodically renew your SSL certificate to maintain its validity and continue providing a secure browsing experience to your visitors.
