Welcome to our guide on different certs on Nginx server, where we will explore the benefits and drawbacks of using different types of certificates. With the growing demand for secure online transactions and data protection, it’s essential to ensure that your web server is equipped with the right type of SSL/TLS certificates to offer optimum security to your users.
Before we delve into the details of different certs on Nginx server, let’s first understand what SSL/TLS certificates are and how they work.
What are SSL/TLS Certificates?
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols that provide secure communication over the internet. SSL/TLS certificates, also known as digital certificates, are files that contain encrypted information about the identity of a website and its owner. When a user visits a website, their browser checks the SSL/TLS certificate to verify the website’s identity and establish an encrypted connection to protect the user’s data.
The Importance of SSL/TLS Certificates
SSL/TLS certificates play a vital role in ensuring online security, privacy, and data protection. Without valid SSL/TLS certificates, your website may be vulnerable to various cyber threats, such as hacking, phishing, and malware attacks. Google and other search engines also prioritize websites with SSL/TLS certificates, which means that having an SSL/TLS certificate can also improve your website’s search engine rankings.
Types of SSL/TLS Certificates
There are several types of SSL/TLS certificates available, each with its own set of features, benefits, and limitations. Some of the most commonly used SSL/TLS certificates are:
1. Domain Validated (DV) Certificates
Domain Validated (DV) certificates are the most basic type of SSL/TLS certificates that are issued after verifying the domain ownership. These certificates are ideal for small websites and blogs that don’t require severe security measures.
Advantages of DV Certificates
✨ Easy to obtain and install
✨ Affordable pricing
✨ Ideal for small websites and blogs
Disadvantages of DV Certificates
❌ Only verifies domain ownership, not the identity of the website owner
❌ Less secure than other types of SSL/TLS certificates
❌ Not recommended for e-commerce or financial websites
2. Organization Validated (OV) Certificates
Organization Validated (OV) certificates are a step up from DV certificates, and they require the verification of the organization’s identity in addition to the domain ownership. These certificates are suitable for businesses and organizations that require moderate security measures.
Advantages of OV Certificates
✨ Verifies the identity of the organization
✨ More secure than DV certificates
✨ Ideal for small to medium-sized businesses
Disadvantages of OV Certificates
❌ Relatively expensive than DV certificates
❌ May take longer to obtain and install
❌ Not recommended for high-risk websites
3. Extended Validation (EV) Certificates
Extended Validation (EV) certificates are the highest level of SSL/TLS certificates, offering the most comprehensive security features. These certificates require a thorough identity verification process that includes company name, address, and legal existence. EV certificates are ideal for e-commerce, financial, or other high-risk websites that require top-level security measures.
Advantages of EV Certificates
✨ Highest level of security
✨ Verifies the identity of the organization
✨ Displays a green padlock on the browser, indicating a secure connection
Disadvantages of EV Certificates
❌ The most expensive type of SSL/TLS certificates
❌ May take several days or weeks to obtain and install
❌ Not recommended for small websites without sensitive data transmission

Frequently Asked Questions (FAQs)
1. Why do I need an SSL/TLS certificate for my website?
An SSL/TLS certificate provides secure communication and data protection for your website users. It also improves your website’s search engine rankings and credibility.
2. How do I install an SSL/TLS certificate on my Nginx server?
You can install an SSL/TLS certificate on your Nginx server by following the vendor’s instructions or using a web host that provides automatic SSL/TLS installation.
3. Can I use a free SSL/TLS certificate for my website?
Yes, there are several free SSL/TLS certificates available, such as Let’s Encrypt. However, free SSL/TLS certificates may have some limitations and may not offer the same level of security as paid certificates.
4. How long does it take to obtain an SSL/TLS certificate?
The time required to obtain an SSL/TLS certificate may vary depending on the type of certificate and the vendor. Typically, it may take a few minutes to a few days to obtain and install an SSL/TLS certificate.

Yes, you can use multiple SSL/TLS certificates on your Nginx server, such as for multiple domains or subdomains. However, you need to configure Nginx correctly to avoid any conflicts or security issues.
6. What is the difference between HTTP and HTTPS?
HTTP (Hypertext Transfer Protocol) is the traditional protocol used for web communication, while HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that uses SSL/TLS certificates to encrypt data and protect users’ privacy.
7. How do I know if my website has an SSL/TLS certificate?
You can check if your website has an SSL/TLS certificate by looking for a padlock icon in the browser’s address bar or checking the URL, which should start with “https” instead of “http”.
8. Can an SSL/TLS certificate guarantee 100% security?
No, an SSL/TLS certificate can provide essential security measures, but it cannot guarantee 100% security against all cyber threats. It’s essential to follow other best practices, such as using strong passwords and updating your software regularly.
9. What is the difference between SSL and TLS?
SSL (Secure Sockets Layer) is an older protocol for secure communication, while TLS (Transport Layer Security) is a newer and more advanced protocol that replaced SSL.
10. Are SSL/TLS certificates compatible with all browsers and devices?
Most SSL/TLS certificates are compatible with all popular browsers and devices. However, some older browsers may not support the latest SSL/TLS protocols, which may lead to compatibility issues.
11. What happens if my SSL/TLS certificate expires?
If your SSL/TLS certificate expires, your website will display a security warning to users, and they may not be able to access your website until you renew your certificate.
12. Can I transfer my SSL/TLS certificate to a different server?
Yes, you can transfer your SSL/TLS certificate to a different server by exporting the certificate files and importing them to the new server.
