In this post I will take you through a concept called steganography using which, it is possible to hide your secret information in image files, songs or any other file of your choice.
There are many steganography tools available online but only a few are able to work flawlessly.. However I have managed to get a tool that can work perfectly on all types of files and all size of data. The tool is called “Stego Magic“. You can download it from the following link.
The zip file contains two versions of Stego Magic: One for encrypting the text messages and the other for encrypting binary files. StegoMagic_TXT can be used to hide text messages in other files such as an image or a sound file. StegoMagic_BIN can be used to hide one binary file in another such as an executable file inside an image or an image inside a video file.
With Stego Magic, there is no limitation on the size and type of the file that you are intending to hide.
At the end of the encryption process, a secret decryption key will be generated and the same is required during the decryption process.
How to Use ?
Suppose you want to hide a text message inside a JPG file:
1. Place the JPG and the text file (.txt) in the same folder as that of StegoMagic_TXT.exe
2. Run StegoMagic_TXT.exe and follow the screen instructions to embed the text message inside the JPG image.
3. Note down the secret decryption key.
Now you can send this image to your friend via email. To decrypt the hidden message, your friend should load this JPG file onto the Stego Magic tool and use the secret decryption key.
