Steghide

What is Steghide and why is it used?

Steghide is a steganography program that helps in hiding data in various kinds of image and audio files. In this process, the color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests.

• Steghide supports file formats like JPEG, BMP, WAV and AU. File formats like PNG are not supported with this tool.

To check whether a file has Steganography embedded data:

# Displays info about a file (whether it contains embedded data)
steghide info < file-name >

Extract data

Of course, it can also do the reverse and extract the data from these files. The most basic command is:

steghide extract -sf < file-name >
