+Product: Mono: Class Libraries

+TargetMilestone: ---
+Summary: MONO PKCS7 signed by RSAManaged cannot be verified by Microsoft components.
+Performing a PKCS7 signature using the Mono RSAManaged class, results in
+a PKCS7 object which cannot be verified by the MS CAPICOM component.
+Furthermore, wrapping the PKCS7 in a S/MIME construct and trying to verify
+using Outlook Express or Outlook also fails. In all these cases it is the
+signature verification which fails. If one uses the MS
+RSACryptoServiceProvider class instead, everything works ok.
+Interestingly, trying to verify the same PKCS7 using openssl or Mozilla
+Thunderbird(S/MIME) succeeds.
+Steps to reproduce the problem:
+  1. You need a RSA key and a corresponding certificate.
+  2. Create an instance of the RSAManaged class.
+  3. Import your RSA key into the RSAManaged instance.
+  4. Create a PKCS7 using your RSAManaged instance for signing,
+     and also adding the certificate..
+  5. Verify the PKCS7 using the CAPICOM.SignedData object.
+Actual Results: 
+  CAPICOM throws an exception with message 'Invalid Signature'
+Expected Results:
+  Success ie no exception
+How often does this happen? 
+  Everytime
