  3. Output encoding is required for the data to be sent over an SSL channel.

  4. Output encoding ensures that the client will treat all data received as data and not as executable scripts.

  3. The Android application (the client) supplies a certificate to identify itself in addition to the server performing the same task, so that the client’s identity is authenticated to the server.

  4. The client decides to reject or accept the connection with the server based on its own criteria about the validity of the server’s SSL certificate.
