Hi, I am a java programmer and I have 1 and a half years of experience. Could anyone assist me with the following?

I need to find a component that can run in both Windows, Mac OS and Linux that can do the following:
Compress a file then encrypt the compressed file. The application must compress a .dat file to a .zip file that is password protected.

A sample code would help me too. Please...

Solution 2

Java SDK provides classes both for compression (see for instance Class Deflater[^]) and encryption (see JavaTM Cryptography Extension (JCE)[^]).
