steganography and file marking tool OpenPuff is a steganography and file marking tool that enables you to hide sensitive data inside images, audio files, videos and Flash files. It supports 512bit key cryptography with SHA512 password extension as well as data scrambling, data whitening and creation of decoy data. Your sensitive data can even be chained across multiple files. In addition to hiding data, the program can also be used to apply a, invisible digital watermark to any of the supported file types, allowing you to prove ownership or verify file integrity. Despite the advanced features, OpenPuff is easy to use with a self-explaining interface. Copyright

Hidden and well 5 stars by gimpguy Aug 07, 2012 (Read all my 1159 reviews)
I tested this with a simple text document using a .png image as the carrier. There was no way to tell from any standard inspection that there was a .txt file attached unless I used the unhide option in OP. That is very cool and yet scary at the same time. Sure this has been around for some time, the ability to do this and even long prior to computers but still very cool. For sensitive information like software keys, etc... if you don't want someone finding out what they are, put em in a doc, hide it with OP using an image carrier or something else and there you go. This has triple password options in case someone tries to break into it. While I admit, I have no real need to hide anything, it's still a very handy program, definitely a 5. show Review details
