Verify message

["Bob Smith" <brbdw@xxxxxxxxxxx>]

I'm trying to verify a multi-part signed message and I'm getting the 
following error: "encapsulated content digest != message digest attribute"

I tried using the example provided in the sfl_guide3.doc document. I used 
the following for the encapsulated content:
-----
Content-Type: Text/Plain
Content-Transfer-Encoding: 7bit
Content-Description: text, unencoded

SignedData5.in Content.

This is a FREE CTI Test content with Elmer Fudd DSA Cert AND Bugs Bunny 
Certs.
It also handles the alternative API calls for SignedData, so it contains a 
number of
additional keywords (including content in a file).

-----
Here's my code...


		CSM_Buffer bufMessage(encapcontent, length);

		CSM_ContentInfoMsg contentInfo;
		contentInfo.SetEncodedCI(buf);
		if(contentInfo.IsSignedData())
		{
			CSM_MsgToVerify msg;

			// Create an empty list of CounterSignature Signer IDs
			CSM_RecipientIDLst *pCSSIDNoCertsLst =
				new CSM_RecipientIDLst;

			long lRet = 0L;
			CSM_Content content(&bufMessage);
			if ((lRet = msg.PreProc(pCSMIME,
								&(contentInfo.AccessEncapContent()->m_content),
								pCSSIDNoCertsLst)) == SM_NO_ERROR)
			{
				// set the encapsulated content and the content type
				msg.SetEncapContent(&bufMessage,
					CSM_Content::CONTENT_DATA_DATA);
				long l2 = msg.Verify(pCSMIME);



Verify is throwing an exception after the following line in 
sm_MsgSignerInfo.cpp:

               if (pMessageDigest->Compare( encapContentDigest ) != 0)
               {



I also tried to use Outlook Express to generate the SignerInfo with the same 
results.

Any help would be greatly appreciated.

Thanks,

Bob Smith
