SUBMIT certificate request - outside domain

Question

Hello

I need to submit a PKCS#10 certificate request to a certificate authority who is outside my domain. This article in MSDN shows a way to submit certificate requests within a network using ICertRequest2 COM object.

hr = CertRequest->Submit( CR_IN_ENCODEANY | CR_IN_FORMATANY, RequestStr,
                          AttributesStr, CAName, &Disp );

where

BSTR CAName = SysAllocString( L"COMPUTERNAME\\CA Name" );

My question is how do i submit my request progrmatically from the client who is outside the Domain.

I don't want to use the Microsoft web enrollment pages, as this needs to be a automated process.

My CA is 2003 Enterprise and client is XP SP3.

Any ideas please?

Thanks

In general, this can be done in few ways

1. Manually with some audit procedures between the CA and the participating entity/user

2. Semi automatically using the MS windows provided web URL/enrolment page, certsrv

3. Write your own solution, say, a web service to liaise between user and the CA
