How to Download Dummy SSL Certificate for Testing Purposes
If you are developing or testing a website that requires HTTPS protocol, you may need a dummy SSL certificate to simulate a secure connection. A dummy SSL certificate is a self-signed certificate that is not issued by a trusted certificate authority (CA). It can be used for testing purposes only, as it will not be recognized by browsers or clients as valid. In this article, we will explain what a dummy SSL certificate is, why you may want to use it, how to create one using OpenSSL, how to download one from online tools, and how to install and test one on your web server.
What is a Dummy SSL Certificate and Why Use It?
Definition and Explanation of Dummy SSL Certificate
An SSL certificate is a digital document that authenticates the identity of a website and encrypts the data exchanged between the web server and the web browser. It ensures that the information transferred over the internet is secure and confidential. An SSL certificate contains information such as the domain name, the owner name, the issuer name, the expiration date, and the public key.

A dummy SSL certificate is a type of SSL certificate that is not issued by a trusted CA, but by yourself or by an online tool. It is also called a self-signed certificate, because it is signed by its own private key. A dummy SSL certificate can be used for testing purposes only, as it will not be trusted by browsers or clients. If you use a dummy SSL certificate on your website, your visitors will see a warning message that your connection is not secure and your identity is not verified.
Benefits and Drawbacks of Using Dummy SSL Certificate
There are some benefits and drawbacks of using a dummy SSL certificate for testing purposes. Here are some of them:
Benefits:
You can create and download a dummy SSL certificate for free, without paying any fees to a CA.
You can test your website functionality and security with HTTPS protocol, without exposing your real data or credentials.
You can learn how to generate, install, and manage SSL certificates, without risking any errors or damages on your production website.
Drawbacks:
You cannot use a dummy SSL certificate on your production website, as it will not be trusted by browsers or clients.
You may encounter some errors or warnings when testing your website with a dummy SSL certificate, as some features or functions may not work properly with an untrusted certificate.
You may compromise your website security if you use a dummy SSL certificate that is generated by an online tool that is not reliable or reputable.
How to Create a Dummy SSL Certificate Using OpenSSL
Steps to Install OpenSSL on Windows or Linux
One way to create a dummy SSL certificate is to use OpenSSL, an open source software that provides cryptographic functions and tools. OpenSSL can run on various operating systems, such as Windows or Linux. Here are the steps to install OpenSSL on Windows or Linux:
WindowsLinux
openssl version to verify that OpenSSL is installed correctly.
sudo apt update or sudo yum update, depending on your Linux distribution. - Install OpenSSL by running sudo apt install openssl or sudo yum install openssl, depending on your Linux distribution. - Open a terminal and type openssl version to verify that OpenSSL is installed correctly.
Steps to Generate a Private Key and a Self-Signed Certificate
After installing OpenSSL, you can use it to generate a private key and a self-signed certificate for your dummy SSL certificate. Here are the steps to do so:
Create a folder to store your private key and certificate files, such as C:\OpenSSL\certs or /home/user/OpenSSL/certs.
Navigate to the folder you created by running cd C:\OpenSSL\certs or cd /home/user/OpenSSL/certs.
Generate a 2048-bit RSA private key by running openssl genrsa -out private.key 2048. This will create a file named private.key in your folder.
Generate a self-signed certificate by running openssl req -x509 -new -key private.key -out certificate.crt -days 365. This will create a file named certificate.crt in your folder. You will be prompted to enter some information about your website, such as the country name, the state name, the organization name, the common name, etc. The common name should match the domain name of your website, such as example.com.
You have now created a dummy SSL certificate using OpenSSL. You can view the details of your certificate by running openssl x509 -in certificate.crt -text -noout.
Steps to Create a PFX File if Needed
Sometimes, you may need to create a PFX file that contains both your private key and your certificate in one file. A PFX file is also called a PKCS#12 file or a personal information exchange file. It is usually required by some web servers, such as IIS. Here are the steps to create a PFX file using OpenSSL:
Navigate to the folder where you stored your private key and certificate files by running cd C:\OpenSSL\certs or cd /home/user/OpenSSL/certs.
Create a PFX file by running openssl pkcs12 -export -out certificate.pfx -inkey private.key -in certificate.crt. This will create a file named certificate.pfx in your folder. You will be prompted to enter a password to protect your PFX file.
You have now created a PFX file using OpenSSL. You can view the details of your PFX file by running openssl pkcs12 -in certificate.pfx -info -noout.

FAQs
Here are some frequently asked questions about dummy SSL certificates:
Q: What is the difference between a dummy SSL certificate and a real SSL certificate?
A: A dummy SSL certificate is a self-signed certificate that is not issued by a trusted CA, but by yourself or by an online tool. It can be used for testing purposes only, as it will not be trusted by browsers or clients as valid. A real SSL certificate is a certificate that is issued by a trusted CA, such as Let's Encrypt, Comodo, or DigiCert. It can be used for production websites, as it will be recognized by browsers or clients as valid.
Q: How can I get a real SSL certificate for my production website?
A: You can get a real SSL certificate for your production website from various sources, such as:
Your web hosting provider: Some web hosting providers offer free or paid SSL certificates for their customers. You can check with your web hosting provider if they offer this service and how to get it.
A trusted CA: You can purchase an SSL certificate from a trusted CA, such as Let's Encrypt, Comodo, or DigiCert. You can choose from different types of certificates, such as domain validation (DV), organization validation (OV), or extended validation (EV), depending on your needs and budget.
A third-party service: You can use a third-party service that provides free or paid SSL certificates for your website, such as Cloudflare, Certbot, or ZeroSSL. You can follow their instructions on how to get and install their certificates on your web server.
Q: How long does a dummy SSL certificate last?
A: A dummy SSL certificate has an expiration date that depends on how you create it. If you use OpenSSL to create a dummy SSL certificate, you can specify the validity period of your certificate when you generate it. The default validity period is one year. If you use an online tool to create a dummy SSL certificate , you may have a different validity period depending on the tool. For example, ZeroSSL Free SSL Certificate Generator and SSL For Free offer certificates that are valid for 90 days. You can check the expiration date of your certificate by viewing its details on your web browser or using an online tool such as SSL Checker.
Q: How can I renew or extend a dummy SSL certificate?
A: You cannot renew or extend a dummy SSL certificate, as it is not issued by a trusted CA. You can only create or download a new dummy SSL certificate and replace the old one on your web server. You should also update your web server configuration file to reflect the changes.
Q: How can I remove or uninstall a dummy SSL certificate from my web server?
A: You can remove or uninstall a dummy SSL certificate from your web server by following these steps:
Edit your web server configuration file to disable HTTPS protocol and remove the lines that specify the path of your certificate and your private key files.
Save and restart your web server to apply the changes.
Delete your certificate and your private key files from your web server.
