I’m trying to make a certificate for testing and I am using this site How to: Create Your Own Test Certificate as a tutorial on how to but when it comes time to enter in the password after you create the password it says failed in the command prompt why is that?

What I’ve done:

First, I open a command prompt and type in:

  cd C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin

Second, I type in

  makecert -sv myPrivateKeyFile.pvk -n "TestCert" myCertFile.cer -b 01/01/2011 -e 01/01/2015 -r

Then I create the password then enter the password on the sencond pop up box and then it says failed in command prompt

When I enter in this again, the popup is asking for the password pops up first this time, and I enter it in and it says:

Error: CryptCertStrToNameW failed => 0x80092023 (-2146885597)

    makecert -sv myPrivateKeyFile.pvk -n "TestCert" myCertFile.cer -b 01/01/2011 -e 01/01/2015 -r

    The reason why I was getting this error is, because I didn’t right click on cmd when I ran it. So when you have this problem you need to right click on cmd and then run as administrator and see if that fixes your problem as it did mine.
