Wrong PIN when initializing RSACryptoServiceProvider with smart card

Question

I get a "wrong PIN" exception initializing RSACryptoServiceProvider this way in Visual Studio C++ 2012:
array<System::Byte>^ Sign(array<System::Byte>^ BinDataToSign, X509Certificate2^ Certificate, String^ ProviderName)
//Set Password
System::Security::SecureString^ secString = gcnew System::Security::SecureString();
secString->AppendChar(wchar_t("1"));
secString->AppendChar(wchar_t("1"));
secString->AppendChar(wchar_t("1"));
secString->AppendChar(wchar_t("1"));
System::Security::AccessControl::CryptoKeySecurity^ cryptoSecurityKey = gcnew System::Security::AccessControl::CryptoKeySecurity();
CspParameters^ cspa = gcnew CspParameters(1, ProviderName, "8ed9f3ef2dffe62d154f2d82546c337521096e", cryptoSecurityKey, secString);
RSACryptoServiceProvider^ csp = gcnew RSACryptoServiceProvider(cspa);
That is not the actual pin in the example, but I have checked and verified that I am using the correct PIN. Maybe it has something to do with character type convertion when appending to the secure string?

Hi Andrius, Why not set a breakpointer in your function and step by step debugging your code? So you could see the value of secString and any others variables. If you get a unexpect value, so you will know where make the problem in your code. Anything you
want to know, please don't hesitate and post it here.
