How to encrypt with 3DES – DESede from Bouncy Castle API in J2ME applications

In this post we will see how to use the 3DES (Triple Data Encryption Standard in EDE mode) or DESede algorithm implementation from the Bouncy Castle API for J2ME platform. The example will use the 3DES lightweight engine to encrypt and decrypt a file managed by a J2ME (MIDlet) application.

The Bouncy Castle Crypto API for Java provides a lightweight cryptographic API that works with everything from the J2ME to the JDK 1.6 platform. The API is different for J2ME platform than the one for JDK platform. For example, the lightweight API has different implementations for the two platforms:
