I am working on signing and encrypting XML file with certificate in smart
card. The following code I used on .net 1.1, it works fine
CspParameters CSPParam = new CspParameters();
CSPParam.KeyContainerName = "MY";
CSPParam.ProviderName = DATAKEY_RSA_SCARD_PROV; //Smart card CSP

//"Datakey RSA CSP"
CSPParam.ProviderType = (int)CryptoCom.PROV_RSA_FULL;
CSPParam.KeyNumber = 2; // (int)KeyNumber.Signature;
RSACryptoServiceProvider Key = new RSACryptoServiceProvider(CSPParam);

Since I want to use .net 2.0 XML encryption API. I switch the same code to
.net 2.0 platform. It throw anexception at last statement with error "More
data uis available". Anyone knows what is the problem? Thanks.

I didn’t get feed back yet. I send a bug report to MS, but didn’t get
response either. Are you working on encryption of XML file? Actually, I try
to encrypt XML element in XML, it works ok, but when I decrypt the file, it
throws same error “More data is available”. Do you have same problem?

It's clear that the problem is when trying to access to the private ke
stored in the card.

My guess (I can't assure that) is that is necessary to set the passwor
of the card somehow. May be this problem is related with the followin
bug:

But I cannot asure that. So I will think moving back to version 1.1. D
you know how can I set Visual Studio 2005 to work with version 1.1 o
the framework?

Thanks
