Steghide Tutorial/Demo

Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. ‘Steghide’ is a pretty useful tool (steganography program) that lets you encrypt and hide a file inside another file’s content, so it’ll be ‘invisible’ to others (under most situations) thus helping while enhancing the security of your sensitive data. For example, let’s say you encrypted and attached a text file into an image, then there’s no way that anyone (most users at least) could even suspect, that particular image has a text file, hidden inside. The image will appear to be perfectly normal, anyone can view it etc, yet, the attached text file won’t be visible. Even if they were able to find that there’s a text or something is attached to it (by using a special tool), because it’s encrypted, unless they know the password, they won’t be able read its content. This is what ‘Steghide’ basically does. First it compress and then encrypts the file using AES (powerful algorithm) and at the end (after attaching it), verifies the integrity.
