IT:AD:Certificates:HowTo:Export from a Cert Store a Private Key
Summary
It's pretty rare to need to export a private key (usually you'll be installing a *.pfx file), but maybe you need to export for safe keeping a cert generated and installed by a wizard – such as the one built into IIS, that creates and installs the cert into both the My and Root cert stores:
Process
Select the cert and select the export function:
Specify that you don't just want the public key certificate, but the private key as well:
And specify the format that will allow you to export a combined *.cer and *.pvk:
Note: have to admit that I'm not sure why it offers you a choice of format once you've specified that you want the private key -- as far as I know, the *.pfx is the only format that allows for both to be combined....Hum...
Specify a mandatory password to protect the exported private key:
Select where you want the *.pfx file to be generated:
Done:
