hi,
I need a good java-based steganalysis tool to analyze the efficiency of a steganographic application. I searched a lot on internet. But failed to get a suitable one. Can anyone please give me a link to download such an application in free? Thanks in advance in anticipation of an early reply.

This is portion of my code. Here I wrote a method 'stegProcess' that returns a byte[]. I want to write an image file from this byte array. But getting this error, "java.lang.IllegalArgumentException: im == null!". This code works fine if I commented out the call to 'stegProcess'. Another important point is that I am getting a value for in.available(), like.. Available: 53270

Thanks you very much in anticipation of an early reply.
