In our tests, we found the program easily handled smaller text files and documents, and even program files, but struggled with larger files that had already been compressed, such as PDFs or other JPEG files. As files are added, the program attempts to compress the image to free up space to accommodate them without growing the overall size – this makes sense, as trying to pass off a 3MB image as a 10MB image because a 7MB file has been embedded inside it would arouse suspicion. Next, choose your target image file bearing in mind the following restriction: SteganPEG won’t allow you to add any files that result in the original image’s file size being exceeded. NET Framework 3.5 or later installed (standard from Windows 7 onwards) – just fire up the program.įirst, leave the option for embedding selected, then enter a password to encrypt the files within the image for extra protection. The host file appears to be completely normal, and unless you know there’s something there and have the right tools to get to that information, it can pass unnoticed.Īs its name implies, SteganoPEG is a simple tool designed to let you hide files inside JPEG files.
It’s a good way to share confidential information because you’re effectively doing so in plain sight. Steganography in computing terms is the art of hiding messages, images or even complete files – inside other files.
