What is SSL certificate & Can I create my own SSL certificate for my website?
What is SSL certificate?
SSL works by protecting the data exchanged between a user’s browser and the web server, hence other details such as passwords, payment details and personal details are kept safe from any interceptor.
Key Features of an SSL Certificate:
- Encryption: Safeguards that data that is in transit is not accessed by unauthorized persons.
- Authentication: SSL establishes that the user communicates with the correct website and that the website is not a fake.
- Data Integrity: Helps guard information against attempts that may be made to change it as it is transmitted.
- Trust Indicators: Triggers such visual signs as the ‘lock’ beside the web address and the change of the address to begin with ‘https://’.
- SEO Benefits: Google then deems websites that use SSL as a factor, prioritizing secure websites over an insecure one when being ranked on in a search engine.
Types of SSL Certificates:
- Domain Validation (DV): I checks that a domain belongs to whom it claims to belong to and is the least secure type of SSL.
- Organization Validation (OV): Identifies the organization standing behind the specific domain and offers more assurance.
- Extended Validation (EV): Provides the greatest degree of assurance and frequently includes the company logo in the browser address line.
- Wildcard SSL: The process of securing a domain as well as all the subdomains that belong to it.
- Multi-Domain SSL: The value of a single certificate spans across the different domains.
How They Work: Is It Possible to Create Your Own SSL Certificate?
Yes, it is possible to generate a certificate on your own, however, certificates that you generate are known as self generated SSL certificates, because they are not signed by any usual Certificate Authority. However, they are produced and “authenticated” by You – being the independent owner or the administrator of the website.
Benefits of a Self-Signed SSL Certificate:
- Free of Cost: It is not mandatory that you buy it from a CA, however you should have the necessary knowledge of it as programmed in this assignment.
- Quick to Set Up: Appropriate for experiments, intra-business initiatives, or websites which should not be seen by the general public.
- No Third-Party Dependence: Also, you have the rights of generation and utilization of the certificate which can benefit your business.
How to Create a Self-Signed Certificate:
If you want to create a SSL certificate there are many tools for this function such as OpenSSL but you can create self-signed SSL certificate. Here is a simplified process:

- Generate a private key.
- Create a Certificate Signing Request or CSR.
- You will generate a self signed certificate from the CSR and your private key.
Example command:
Copy code
You’ll end up with two files:
- selfsigned.key is the private key that is used for the creation of the security.
- selfsigned.crt (this is another Necessary file which is also known as SSL certificate)
Limitations of Self-Signed SSL Certificates:
- Not Trusted by Browsers: Any browser will display a warning when accessing a site with a self-signed certificate, saying that the page’s connection is not safe. This undermines user trust.
- No Third-Party Validation: Even though getting a website certified is a good thing, your website is not independently certified making it less reliable.
- Limited Use Cases: Well suited for development, testing or intranet purposes but not for highly visible website.
For Public Websites: The use of a trusted certificate authority:
To anyone managing any website that is online and open for public use, it is crucial to use certificates issued by CA. Reputable CAs confirm that your website is not fake and they award SSL certificates that browsers do not display security warnings.
