Steganography

Steganography is practically a technique for hiding a file or something into a file in this case a file with an image type.



Seen here are two files ie
1. Archl.png [ used to hold secret files that are inserted ]
2. snx_install.sh [ file to be hidden in an image -> Archl.png ]

 

 Compress_file is hidden in zip format
 

 Hide files in Archl.png image then rename, here renamed by name Archl-imut.png


 You can see the files that have been hidden in an image, let us delete all existing files except the image files that already have files hidden in them.
extractFile which will already have hidden files.






       
And voila the file that was hidden in the image now exists again after extracting it.
