Security - SATSAMIDlet

Description

This example MIDlet shows you how to encrypt and decrypt messages using the SATSA-CRYPTO API. The MIDlet allows the user to store messages that are encrypted with a 128-bit Advanced Encryption Standard (AES) key. The AES encryption is symmetric, which means that there is only one key used for both encryption and decryption. The MIDlet stores the messages in its record store for later retrieval.
