Assignment 3: Steganography, more challenging

Your assignment is to analyze the file sun-augmented.jpg.

There are two programs on the 45.56.74.139 server that might help you: steghide and snow. One of these two programs was used to put a hidden message in the file.

Your task is to extract the cleartext of the hidden message (the cleartext message is in English); save that on the server in a file called "CIS4385-assignment-3-cleartext.txt".

In this case, you also know that there is a password, and that it is four characters long. Please assume that it is a common English word contained in /usr/local/share/dictionary/words on the server (thus, there are only 5110 possibilities.)

You don't have to submit anything; the grader will simply review your cleartext file found on the server to make sure that it is the correct file. This file must be in your home directory by the beginning of class on Tuesday, February 11. Since I will use an automated process to collect it, please make sure that the filename is exactly the same as the specified one.
