WHAT IS STEGHIDE ?
Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests.
Features include the compression of the embedded data,
encryption of the embedded data and automatic integrity
checking using a checksum. The JPEG, BMP, WAV and AU file
formats are supported for use as cover file. There are no
restrictions on the format of the secret data.
How does it hide files (simple explanation)?
According to its manual, this is what it does.
If you hide a text file using an image, then after ‘Steghide’ encrypts and compresses the text file, it’ll also ‘convert’ its data to look like it holds data of an image (pixels!). If you use an audio file instead of the image, then it’ll ‘convert’ the text data into ‘audio samples’. That’s how the data becomes ‘invisible’ once gets mixed.
