In this tutorial, you'll employ the open standard Bouncy Castle to encrypt mobile MIDlet applications. The tutorial provides an overview of how to encrypt application-related data in a Java 2 Micro Edition (J2ME) application. It begins with a brief introduction to data encryption, then continues on to introduce the open source obfuscator, ProGuard. The final section in this tutorial compares MIDlet JAR file sizes, with and without obfuscation.

Prerequisites

To use this course, you should be familiar with basic Java programming and Java 2 Micro Edition (J2ME).
