Set read permission for certificate from command line

Can anyone point me in the right dire开发者_高级运维ction for managing read permissions for certificates from the command line? I'm scripting our certificate installation, and need to allow NetworkService to access 2 certificates in the "Local Computer\Personal\Certificates" store.

Thanks in advance

I've done that to grant a our web application access to a private key of a cert that was installed in windows.

Here's a powershell script. It relies on FindPrivateKey.exe from Microsoft.

# Use FindPrivateKey.exe (From Windows SDK) to get the file name of the private key.
$s = cmd /c "FindPrivateKey.exe My LocalMachine -t   `"9D1F685D554E5B04C591D7967FB0D151153A25D8`" -a"

# Grant read access on the private key
cmd /c "cacls.exe `"$s`" /E /G `"IIS_IUSRS`":R"
