OpenStego icon An easy-to-use software tool that enables you to hide messages within your images, password-protect them, as well as compress the files

OpenStego is a lightweight Windows application designed specifically for helping you embed sensitive information in images, while offering support for encryption and compression options.

Clean feature lineup

You are welcomed by a simple layout that offers several configuration settings for helping you hide private data into images, and extract the encrypted text as well.

Since this is a Java-based utility, so you should make sure you have previously installed the working environment on the computer, otherwise you cannot run the tool.

Concealing and encryption capabilities

OpenStego gives you the possibility to select the file that you want to conceal, choose the algorithm (LSB or random LSB), embed the same message in multiple cover files (e.g. JPG, BMP, GIF, PNG), as well as specify the output directory.

What’s more, the tool offers support for encryption options for adding an extra security layer to your important information. You can encrypt files by setting up passwords and compress the pictures for not drawing other users’ attention upon large-sized photos.

Advanced users may also use random images as cover files and select the number of maximum bits to use per color channel. The extraction process can be carried out by selecting the input file, specifying the output directory, as well as entering the password.

During our testing we have noticed that OpenStego accomplishes a task pretty quickly. However, just like any similar Java tools, it eats up CPU and memory, so your computer performance may be affected.

Bottom line

All in all, OpenStego offers a decent feature pack for helping you hide sensitive information in innocent looking photos, and is suitable for rookies and professionals alike.
