//
// SSecurityFactoryStandard - implementation of the SSecurityFactory
// interface.
//
// Server implementations must define an instance of a
// VncAuthPasswdParameter-based class somewhere.  Any class based on
// VncAuthPasswdParameter will automatically register itself as the
// password parameter to be used by the Standard factory.
//
// Two implementations are provided here:
//
// VncAuthPasswdConfigParameter - reads the password from the Binary
//                                parameter "Password".
// VncAuthPasswdFileParameter   - reads the password from the file named
//                                in the String parameter "PasswordFile".
//
// This factory supports only the "None" and "VncAuth" security types.
