      <para>This class is used to encode and decode the content of the security context token when a binding with message security that uses a stateful security context token is used. crabout stateful security context tokens, see <format type="text/html"><a href="640676b6-c75a-4ff7-aea4-b1a1524d71b2">How To: Create a Stateful Security Context Token for a Secure Session</a></format> topic.</para>
      <para>Microsoft’s version of <see cref="T:System.ServiceModel.Security.SecurityStateEncoder" /> is <see cref="T:System.ServiceModel.Security.DataProtectionSecurityStateEncoder" />. It uses Microsoft’s <see cref="http://go.microsoft.com/fwlink/?LinkId=96704">Windows Data Protection (DPAPI)</see> technology to encrypt/decrypt the cookie. You can plug in a different mechanism for encrypting and decrypting cookies by implementing this class. </para>
      <para>The encoding of the security state must ensure that the state is signed and encrypted for the service. </para>
      <para>This class is used by the server when sending the security state as a cookie in the SecurityContextToken issued to the client.</para>
      <para>An example implementation of this class is an X509CertificateSecurityStateEncoder that uses the service's certificate to sign and encrypt the security state.</para>
