<p>This file contains a simple utility class to store parameters about an SSL Session for reuse later. This class was created to extend the values stored in br_ssl_session_parameters, which allow BearSSL to resume an SSL session. When testing BearSSL's session resumption feature, it was observed that BearSSL can only resume a session that was was started with the same server. This becomes an issue when using repeated requests to a domain name which can resolve to multiple IP addresses ("api.github.com"), as the device will switch between two or three servers. Since BearSSL only stores one session at a time, this results in session resumption being few and far between.</p>
|
||
|
|
<p>To remedy this problem, an <a class="el" href="class_s_s_l_session.html" title="This class stores values which allow SSLClient to save and resume SSL sessions. ">SSLSession</a> stores the IPAddress and hostname, along with the parameters in br_ssl_session_parameters struct. Using this data, <a class="el" href="class_s_s_l_client.html" title="The main SSLClient class. Check out README.md for more info. ">SSLClient</a> is able to remember which IPAddress is associated with which session, allowing it to reconnect to the last IPAddress, as opposed to any associated with the domain. </p>
