Describe when someone would need this information. For example "when connecting to wi-fi for the first time".

Step-by-step guide

Add the steps involved:

1. Create a working directory on the Desktop
   1. We will call it SSL
2. Open the command prompt (CMD)

3. Change directory to the SSL folder we just created

   cd Desktop/SSL

   
   

4. Generate a Certificate Signing Request (CSR)

   openssl req -new -newkey rsa:2048 -nodes -out rdp.csr -keyout rdp.key

   
   

   
   

   You can also use the DigiCert Easy CSR tool.

   
   

5. Get your certificate signed by your Certificate Authority of choice. We recommend DigiCert.
6. Copy your signed certificate into the SSL folder on the Desktop.

7. Create a PKCS#12 archive

   openssl pkcs12 -export -in rdp-signed.crt -inkey rdp.key -out rdp.p12 -certfile more.crt

   
   

   1. If your CA requires an intermediate certificate, append the following to the previous command before submitting it.

      -CAfile "intermediate_cert_from_CA.crt"

      
      

8. Press the Windows key + R to open the Run dialog

9. Run the local computer certificate manager

   certlm.msc

   
   

10. Right-click the Personal store on the left

11. Hover over All Tasks
12. Click Import...
13. Click Next
14. Browse to the .p12 file from step 7
15. Click Next
16. Enter the password, if there is one
17. Click Next
18. Click Next again
19. Click Finish
20. Go to Personal > Certificates
21. Double-click the imported certificate
22. Click the Details tab
23. Scroll down and click Thumbprint
24. Copy the Thumbprint value to the clipboard
25. Paste the thumbprint into Notepad and remove any spaces

26. Open PowerShell and enter the following command, but don't press Enter yet

    wmic /namespace:\\root\cimv2\TerminalServices PATH Win32_TSGeneralSetting Set SSLCertificateSHA1Hash="<certificate thumbprint>"

    
    

27. Replace <certificate thumbprint> with the thumbprint from Notepad

28. Press Enter
29. That's it! Your new certificate should now be active for new RDP connections!
