Steg1.0.0.2

Steg is a small software encryption program specialized in hiding data inside images. The encrypted photos can be opened and act the same as normal ones so other users cannot tell the difference between them. It is cross-platform and written in C++.

Drop it on pen drives

You can take advantage of the application’s portability status and run it on the target system by double-clicking on the executable file because you do not have to follow preset installation steps. Plus, you may open it without administrative privileges. You can keep it saved on USB flash drives and get rid of it using a simple deletion task.

User interface

Steg reveals a well-structured suite of features. Photos can be added in the working environment using the built-in browse button (the drag-and-drop support is not implemented). You can rely on tooltips for viewing short descriptions about the program’s functions. Tooltips are displayed each time you hover your mouse cursor over a specific parameter.

Encryption settings

The application works with the following image formats: JPEG (JPG), TIFF, PNG, and BMP. You can check out a preview of the original and modified file thanks to the dual display mode.What’s more, you are allowed to zoom in or out of pictures, make the window fit the screen, and view information about each photo, such as format, size, and color. You may hide a user-defined file in the target image. The encrypted photo can be exported to PNG or TIF file format.Other important tweaking parameters worth being mentioned enable you to hide random noise within images, embed a user-defined text message, as well as use alpha and RGB channels. Hidden data can be extracted via the program’s interface.

Additional encryption tools

Steg gives you the possibility to generate RSA key-pairs which can be saved to a file on your computer. The RSA key-pairs can be exported to DER, HEX, B64, or RAW file format. Last but not least, you are given the freedom to convert keys to DER, DER, HEX, B64, or RAW file format.

Final remarks

All things considered, Steg comes packed with several handy features for helping you hide sensitive files and private text messages inside photos, and decrypt the information via the application’s interface.
