Linux kernel is in the process of replacing the HTTP links in its source code with HTTPS links. HTTPS is considered more secure than HTTP and can prevent lots of attacks like Man-In-The-Middle attack. Currently there are more than 150 patches submitted by Linux Kernel developers to replace these HTTP links. One thing to be noted is this replacement process is not a manual search and replace process. Indeed, some scripts are created to find out these links and try to find whether there is corresponding HTTPS link available and then do the replacement only if the HTTPS link works....

In this post, I will create a HTTPS server and HTTPS client demo which can establish HTTPS communication between a server and a client using Java. This should be very useful when we want to test our understanding about SSL communication. We will use both a detailed SSL client and a simple HttpsURLConnection as the HTTPS client.Before creating the actual HTTPS server and HTTPS client, we first need to generate the keystore and truststore to be used by the server and client. To generate the keystore, we can follow instructions at Different types of keystore in Java -- JKS. In this demo, we ...
