< 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 >
