Hi,I'm trying to use SignedCms -object to sign messages. I 'm using certificate stored on smart card and don't want to prompt dialog for user to set PIN (because program will run on server). here's code I'm using:

byte[] buffer = "test data to sign";

ContentInfo contentInfo = new ContentInfo(buffer);
SignedCms signedCms = new SignedCms(contentInfo);

CspParameters cspparams = new CspParameters(1,"Personal CSP");
System.Security.SecureString pwstr = new System.Security.SecureString();
pwstr.AppendChar('1');
pwstr.AppendChar('2');
pwstr.AppendChar('3');
pwstr.AppendChar('4');
pwstr.AppendChar('5');
cspparams.KeyPassword = pwstr;
cspparams.Flags = CspProviderFlags.NoPrompt;

CmsSigner cmsSigner = new CmsSigner(cspparams);
cmsSigner.Certificate = m_X509Certificate;

// Sign the CMS/PKCS #7 message.
try {
signedCms.ComputeSignature(cmsSigner, true);
}
// Encode the CMS/PKCS #7 message.
byte[] signature = signedCms.Encode();

Now the problem is that initializing of CmsSigner object throws an CryptographicException with message "bad key". Code works fine if I replace line
CmsSigner cmsSigner = new CmsSigner(cspparams);
with
CmsSigner cmsSigner = new CmsSigner(m_X509Certificate).

Only then it prompts PIN dialog. I believe there must be easy solution for this, but just can't find it.. So I would like to know if my way is even correct way to try to set PIN programmatically?

Thanks in advance,

ps. I know quite similar topics exists allready, but those didn't help me.

There is another thread that dicusses it, there is a reported bug in the .Net framework.

Juksa,

Were you ever to get the problem solved?

If so can you let me know where to look as we are experiencing the same problem with VS2005 and framework 2.0

Thanks in advance.
