Welcome to the steghide website! 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. The current version is 0. For more information, see the full text of the GPL. This release features a new algorithm that makes it undetectable by color-frequency based statistical tests.

This release is intended for testing purposes. You can download it from the sourceforge. Please download it and test it heavily to spot as many bugs as possible before the release of version 0.

If you compile the source code, please run "make check" after running "make" and tell me about every problem that occurs. You should have the following libraries installed to use steghide. Steghide needs this library to convert a passphrase into a form that can be used as input for cryptographic and steganographic algorithms. If you compile steghide without libmcrypt you will not be able to use steghide to encrypt data before embedding nor to extract encrypted data even if you know the correct passphrase.

Without this library you will not be able to embed data in jpeg files nor to extract data from jpeg files. If you compile steghide without having this library installed you will not be able to use steghide to compress data before embedding nor to extract compressed data from a stego-file.

Libmhash is absolutely required to compile steghide. While you can compile it without the other libraries they are highly recommended as major functionality will not be available without them. If you download the Windows version you do not have to worry about the libraries because they come with the package. If you use a major Linux Distribution you probably do not have to worry about the libraries as well, most of them will likely be installed already.

I've been working on a series of bash scripts and I need to automate password entry for batch processing of files and actions.

This isn't for just one program, for example, sometimes it needs to be done for GPG, other times, steghide. There is a specific reason this is being done and I understand the security elements behind it.

This is considered and is negated by how the scripts are stored and working. This simply interactively asked this for every image however: Enter Passphrase: Re-enter Passphrase:. For every image in a directory, this password will be requested and so the password should be able to be stored in a variable and reused. I have been working with steghide most recently but there will also be a need to automate passphrases with GPG at a later date, although there is no need for the methods to be the same.

This can only be used if only one passphrase is supplied. Obviously, this is of very questionable security on a multi-user system. Don't use this option if you can avoid it. Sign up or log in Sign up using Google.

Featured on Meta.Data in the payload may be encrypted using the libraries MCrypt and MHash and compressed thanks to the Zlib library. In addition to the data proper it is also possible to include in the stego file the payload file name and a checksum to verify the integrity of extracted data.

The cryptography algorithm used per default is Rijndael with bit keys which constitutes the Advanced Encryption Standard, or AES in cipher block chaining mode. It is in any case possible to select any algorithm among 18 possibilities, each of which may operate in various modes. To have a complete list of the algorithms and modes of operation you can run steghide --encinfo ; supported algorithms at the time of writing Steghide 0.

Possible commands are embedextractinfoencinfoversionlicensehelp. We mentioned encinfo above and the last three should be pretty obvious; we explain the others, which constitute the heart of Steghide, below. The embed command is used to insert a payload inside a cover file.

In addition to cryptography and the checksum we mentioned, you can also protect your data with a passphrase, that will be requested on extraction. In this phase you can also choose the level of compression to use for the payload, among the nine provided by the Zlib library, as well as the cryptographic algorithm and mode of operation.

It is not mandatory to include the payload file name, nor the checksum; it may be useful not to, when the usable space in the cover file is an issue. In the example the file secret. No other flags are specified, so the payload is compressed and encrypted by default with AES and the embedded file name is added to the payload together with the checksum. In this case the picture.

The passphrase is also specifiable on the command line with the parameter -pallowing the use of this command also in non-interactive contexts.

The extract command is used to extract the payload from the stego file produced. Again usage is very simple, and there are less parameters that can be passed to the executable; you have to specify the name of the file from which to attempt extraction and optionally a passphrase, that will be requested interactively otherwise. It's possible to choose the name of the output file the payload will be saved to:. The last fundamental command is info. With it it becomes possible to gather information on any file among the supported types, like for example to find out about capacity: it can thus be useful before an embedto verify that the chosen cover file may adequately contain the payload to be hidden.

Steghide- Encrypted and Hidden in Plain Sight

The info command may optionally return information on the hidden contents if it is provided the passphrase used during an embed. The next example should make this more easily understandable:. In this example the passphrase is provided interactively but, again, it's possible to use the -p parameter.

Information returned about the payload are the name of the hidden file if included during an embedits size, the cryptographic algorithm used and whether it's compressed or not. The following paragraph explains how Steghide works internally, and is taken from the Steghide manual page:.

Steghide uses a graph-theoretic approach to Steganography. You do not need to know anything about graph theory to use Steghide and you can safely skip the rest of this paragraph if you are not interested in the technical details. The embedding algorithm roughly works as follows: at first, the secret data is compressed and encrypted. Then a sequence of positions of pixels in the cover file is created based on a pseudo-random number generator initialized with the passphrase the secret data will be embedded in the pixels at these positions.

Of these positions those that do not need to be changed because they already contain the correct value by chance are sorted out. Then a graph-theoretic matching algorithm finds pairs of positions such that exchanging their values has the effect of embedding the corresponding part of the secret data. If the algorithm cannot find any more such pairs all exchanges are actually performed.Steganography is a technique used to hide files and sensitive data inside an image so that it can be transported without arousing any suspicion.

It is mostly used for Blackhat Hacking. It is generally encrypted so that data remains secure. This method is one of the basics of cryptography. In this tutorial, we will show you how you can hide files in an image using steghide and Kali Linux.

Steganography is the technique that uses data manipulation to hide secret data inside an image and encrypts it with a secret passkey. The receiver needs the decryption key in order to view the data. We know that Kali Linux is the most used hacking OS in the world. So with that in mind, we will perform this tutorial in Kali Linux just because of its convenience. We will be using Steghide for this tutorial. So without further ado lets begin:. Step 2: Download an image file in which we will hide out text files inside of it.

Step 3: In the Kali Linux terminal. Change the working directory to Desktop using the following command:. Step 4: Make sure that both the files i.

In this tutorial, the directory used is Desktop. You can choose any. I have downloaded an image of a girl. The file is named girl.

The text file is secret. Step 5: Type steghide or steghide -h to show all the option of steghide. Step 6: Now type the following commands to embed the text File into the Image File with a password. So you can enter any password you like, then re-enter the same passphrase to confirm and hit enter. Congratulations you have learned the basics of steganography and using steghide on Kali Linux.

Thanks again.There are various steganography tools available but the part that differentiates it is that it uses a variety of algorithms to encrypt the data. In digital steganography, electronic communications may incorporate steganographic coding inside of a transport layer, such as a document file, picture file, program or convention.

Media records are perfect for steganographic transmission since of their expansive estimate. For instance, a sender might begin with a harmless picture and make few alterations to it in order to hide data, so that, this alteration goes unnoticed for someone who is not particularly seeking out for it. The upside of steganography over cryptography alone is that the planned mystery message does not stand out to itself as an object of examination.

Clearly obvious scrambled messagesā€”regardless of how unbreakableā€”stimulate intrigue, and may in themselves be implicating in nations where encryption is illicit. In this manner, while cryptography is the act of securing the substance of a message alone, steganography is worried about hiding the way that a mystery message is being sent, just as disguising the substance of the message.

Steghide may be a steganography device which permits you to cover up confidential records inside a picture or sound record with a passphrase. By default, its employments Rijndael calculation to scramble the record and the key measure is bits. This tool has its advantages and disadvantages. One upside is that it is significantly better at covering up and can without much of a stretch shroud any document type.

It does as such by utilizing a propelled calculation to shroud it inside the picture or sound record without changing the look or sound of the document. This additionally implies without utilizing steghide or if nothing else a similar scientific methodology as steghide it is hard to extricate the concealed documents from the picture.
