Java Technology Article Examines the Advanced Encryption Standard
A recent article by Rags Srinivas, "Using AES with Java[TM] Technology,"
examines the history and use of the federal standard for private-key or
symmetric cryptography. Particularly, the article examines how the
Advanced Encryption Standard (AES) has been incorporated into several
Java technology offerings; the Java[TM] Cryptography Extension (JCE) was
integrated into the Java[TM] 2 SDK, Standard Edition v1.4.0.
The original AES algorithm that was chosen for the federal standard,
called Rijndael, was invented by two Belgian cryptographers. AES
supports combinations of key and block sizes 128, 192 and 256. As part
of the evaluation process, the algorithms were implemented in the Java
programming language. Since the AES standard was incorporated into the
SDK, support for the JCE has been integrated. As a result, it is no
longer necessary to install the JCE optional package. JCE also has a
provider architecture that allows different providers to be plugged in
under a common framework.
The article primarily looks at AES support in Java[TM] 2 Platform,
Standard Edition (J2SE[TM]), starting with JCE. Code examples are
supplied, and sections are included on strong versus unlimited strength
cryptography and using AES in Java[TM] Secure Socket Extension (JSSE).
The article concludes that the JCE framework is a powerful and flexible
framework for using different cryptographic algorithms.
