DES Java Implementation in JDK by Sun

This section describes how DES algorithm is implemented in JDK. DES algorithm is implemented as part of the JCE package which is integrated in the JDK since version 1.4.

DES algorithm has been implemented in Java by Sun as part of the JDK JCE (Java Cryptography Extension) package. JCE was previously an optional package (extension) to the Java 2 SDK, Standard Edition, versions 1.2.x and 1.3.x. JCE has now been integrated into the Java 2 SDK, version 1.4.x, and new versions.

Sun's implementation of DES includes the following features:

The following JCE classes and interfaces are involved to support DES encryption and decryption:
