Part 1 Using OpenPuff Steganography Unlike cryptography that scrambles a message so that it cannot be viewed, steganography hides the existence of the data. In this project, you will use OpenPuff to create a hidden message. 1. Use your web browser to go to embeddedsw.net/OpenPuff_Steganography_Home.html It is not unusual for websites to change the location of where files are stored. If the URL above no longer functions, open a search engine and search for “OpenPuff.” 2. Click Manual to open the OpenPuff manual. Save this file to your computer.
