The asymmetric algorithm implementation classes that are wrappers around the Windows Crypto API (RSACryptoServiceProvider and DSACryptoServiceProvider) are able to read and write key parameters from the persistent Windows key stores. This class can be used as an argument to the implementation class constructors in order to specify the details of which key store should be used.
