However, for development and testing, you can explore the possibility of creating a self-signed SSL certificate in Windows. Creating a self-signed certificate is an excellent alternative to purchasing and renewing a yearly certification for testing purposes. You can make use of OpenSSL to generate a self-signed certificate for this purpose. In this article, we explore how to create a self-signed certificate in Windows 10. The later part of the article also explores how to deploy the self-signed certificate to client machines. Quick Tip: Although you can save some money if you create a self-signed certificate, it may lead to a permanent block of your website for some users. This is caused by the certificate error message and in most cases cannot be undone. Besides that, the process is time-consuming and really not worth your time which also has a certain cost. We strongly recommend using a 3rd party SSL service provider.

How can I generate a self-signed certificate in Windows 10?

1. Use OpenSSL to create a self-signed certificate

1.1 Install OpenSSL

1.2 Create a public/private key file pair

C: Test>c:opensslbinopenssl ssh-keygen -t rsa -b 4096 -f privkey.pem Once you have the public/private key generated, follow the next set of steps to create a self-signed certificate file on a Windows system.

1.3 Generate a self-signed certificate

If you would rather use PowerShell to create a self-signed certificate, follow the next set of steps instead.

2. Generate a Self-Signed Certificate on Windows using PowerShell

  1. Press the Windows key, and type Powershell in the search box. Right-click on the PowerShell app and select Run as Administrator.

  2. Run the New-SelfsignedCertificate command, as shown below:$cert = New-SelfSignedCertificate -certstorelocation cert:localmachinemy -dnsname testcert.windowsreport.com

  3. This will add the certificate to the locater store on your PC. Replace testcert.windowsreport.com with your domain name in the above command. SPONSORED

  4. Next, create a password for your export file:$pwd = ConvertTo-SecureString -String ‘password!’ -Force -AsPlainText  

  5. Replace Password with your own password.

  6. Enter the following command to export the self-signed certificate:$path = ‘cert:localMachinemy’ + $cert.thumbprint Export-PfxCertificate -cert $path -FilePath c:tempcert.pfx -Password $pwd  

  7. In the above command replace c:temp with the directory where you want to export the file.

  8. You can import the exported file and deploy it for your project.

Another great option to generate a self-signed certificate on Windows 10 is to use a command-line tool such as Powershell. With it, you don’t need to download any third-party software. You just need to input the appropriate command line in Powershell, and the tool will do the job for you.

How to add my self-signed certificate into the curls ca file on Windows 10?

Creating a self-signed certificate using OpenSSL can be done using the Command Prompt or PowerShell. Being able to create your self-signed certificate allows you to create a temporary certificate for in-development projects that require an SSL certificate. We hope you managed to generate a self-signed certificate on your Windows 10 PC. Let us know in the comments section which method you prefer to use.
