In Microsoft System Center Configuration Manager 2007 you serialize a certificate from a PFX file by calling the PxeAuthClass Client COM Automation Class IPxeAuthClass::ReadIdentity Method method.

ReadIdentity has the following parameters:

Parameter	Description
FileName	The path and filename of the PFX file.
FilePassword	The PFX file password.
SMSID	The PXE certificate identifier.

ReadIdentity returns an array containing the following:

Element	Description
0	The hexadecimal-encoded private key for the PFX file containing the certificate.
1	The hexadecimal-encoded certificate.

After you obtain the array, you can use it to submit a registration record by using the SMS_Site class SubmitRegistrationRecord method.

To serialize a certificate from a PFX file

Create an instance of the PxeAuthClass Client COM Automation Class class.
Call the ReadIdentity method.

Example

The following example reads a certificate from a file identified by fileName.

For information about calling the sample code, see How to Call Configuration Manager COM Automation Objects.

Sub SerializeCertFromPFX (fileName, password, smsID)


    Dim pxeauth
    Set pxeauth = CreateObject("Microsoft.ConfigMgr.PXEAuth")

   
    ' Serialize certificate from PFX file.
    

    Dim ident

    ident= pxeauth.ReadIdentity( fileName, password, smsID)
    WScript.Echo "certificatePFX = " & ident(0)
    WScript.Echo "certificate    = " & ident(1)

End Sub

The example method has the following parameters:

Parameter	Type	Description
fileName	VBScript: String	The name and path for the PFX file. For example, \\SERVERNAME\c$\SelfSigned.pfx.
password	VBScript: String	The PFX file password.
