I tried the whole day just to import a certificate in Windows XP, but I always failed. I did following:
Create the certificate with private key (no password):
makecert -sr LocalMachine -ss My -pe -sky exchange -n "CN=TestCert" -a sha1 -sv TestCert.pvk TestCert.cer
Then put certificate and private key together into pfx file:
pvk2pfx.exe -pvk TestCert.pvk -spc TestCert.cer -pfx TestCert.pfx
Import pfx file with command line tool (German System):
winhttpcertcfg.exe -I TestCert.pfx -a NT-AUTORITÄT\NETZWERKDInternet ExplorerNST -c LOCAL_MACHINE\My Error: Unable to import contents of PFX file. Please make sure the filename and path, as well as the password, are correct.
Hint: "NT-AUTORITÄT\NETZWERKDInternet ExplorerNST" --> "NT-AUTHORITY\NETWORKSERVICE"
Filename is ok, password was not set. Even if I set the password (e.g. "MyPassword") in Step 1 and type at the end of step 3:
... -p MyPassword
I got the same error. Then I tried to import in the certificate console (mmc with certificate snap-in). There I got following error: "Der private Schlüssel, den Sie importieren, erfordert möglicherweise einen Dienstanbieter, der nicht installiert ist." --> "The imported private key may requires a service-supplier which is not installed". But the Microsoft Crypto-Service is up and running.
What else can I do?
On Windows Vista and Windows 7, I got this running without these problems.
I need this Certificate to run a WCF Service.
