OpenStego is a picture steganography software that allows to hide data into an image secretly. You can even compress and can set password protection for output image. Thus, even if someone come to know that you have embedded data into the image, then he/she cannot access it without the right password. It’s a handy software to protect confidential text file, zip file, exe file, document, image, or any other data, that is not larger than the source image.
Using OpenStego, you can also hide same message in multiple images simultaneously. These features, such as password protection and compressing data makes it more useful. At present, you can only use images to hide data secretly, but more file types might be used to hide data in future.
Its interface is visible in above screenshot which provides two main tabs to embed data and to extract the output data from image.
Embed tab: Using this tab, you can select a message file (data that you want to hide), a cover file (an image or images in which you want to hide the message file), steganography algorithm (RandomLSB or LSB), output location, and can select encrypt data option to password protect output image that will contain your secret message. You can use jpg, gif, bmp, jpeg, png, and wbmp images as cover files.
You can provide any password and can also enable compress data option to reduce size of output file that can save some disk space.
Use options accordingly and click OK button to get the output image file. Output image looks similar to original image. So it’s very difficult to know that image has any secret message.
To access the embedded file from output image, use Extract tab. Select the input image, provide an output location, and enter password (if provided during embedding process). And with a very short delay, hidden message or data will be in front of you.
