supply public key in CERTENROLL request

Question

I want to request a cert (from AD cert server) using a template. I want to supply the public key in the request. Using msft's SDK sample

        IX509CertificateRequest iRequest = objEnroll.Request;

        // then get the inner PKCS10 request
        IX509CertificateRequest iInnerRequest = 
            iRequest.GetInnerRequest(InnerRequestLevel.LevelInnermost);
        IX509CertificateRequestPkcs10 iRequestPkcs10 = 
            iInnerRequest as IX509CertificateRequestPkcs10;

        // create CX500DistinguishedName
        CX500DistinguishedName objName = new CX500DistinguishedName();
        objName.Encode(subjectName, X500NameFlags.XCN_CERT_NAME_STR_NONE);

        // set up the subject name
        iRequestPkcs10.Subject = objName;

I think I then need to do some thing like this

         iRequestPkcs10.PublicKey.InitializeFromEncodedPublicKeyInfo(xx);

but I dont know what xx is. I have the public key (In a bouncy castle PKCS10 object), but what format must it be in to pass to this function?

You can specify the public key in a number of different formats.

According to MSDN, InitializeFromEncodedPublicKeyInfo takes two parameters: the first is the public key, and the second is an EncodingType enumeration value that specifies the format of the public key you are supplying.

Thx, THis only gives the syntactical encoding (base64, raw hex etc). It doesnt say what data type is expected; I mean if its base64 what bytes were input to the base64 conversion – pm100 Aug 15 '11 at 21:35
