SYMPTOMS

In an application that is built on the Microsoft .NET Framework 2.0, you use the RSA algorithm to encrypt a key that is stored in a smart card. If you use the CspParameters class to programmatically set a password in the application, you receive the following error message:
Incorrect PIN

CAUSE

A function of the RSACryptoServiceProvider class marshals the PIN string, and the PIN string is interpreted as a Unicode string. However, the operating system expects to receive an ANSI string.
