A popular way for people to protect their files is encryption, using programs like TrueCrypt and AxCrypt to prevent unauthorized access to data. The only problem with encryption is it is typically obvious that a file is encrypted. Steganography is a different method of preventing unauthorized access to data and files that solves that problem.

• Steganography - A list of useful tools and resources Steganography. Steganography is hiding a file or a message inside of another file, there are many fun steganography CTF challenges out there where the flag is hidden in an image, audio file or even other types of files. Here is a list of the most tools I use and some other useful resources.
• Jun 22, 2020  Steganofile lets you hide your secret file in one or many host files. It has Encode and Decode buttons on its interface. You can hide your file in another host file (s). Choose the destination folder and set a password of your choice.

What steganography does is it allows you to do is hide files within other files. For example, you can hide a Word file inside an JPG image. On the outside the JPG image is a normal JPG image; it even opens and is viewable like a JPG image. However, under the JPG image is the hidden Word file which can be extracted by the people who know it is there.

Best Free Steganography Program

Program Name:OpenPuff

Developer: Cosimo Oliboni

Download Size: 5 MB

Version Reviewed: 4.00

Supported OS: Windows

Pros

• Allows you to hide any file (regardless of type) inside an image (BMP, JPG, PNG, TGA, PCX), audio (AIFF, MP3, NEXT/SUN, WAV), video (3GP, FLV, MP4, MPG, SWF, VOB), or PDF file
  • Note: Files that hold hidden files are called “carriers”
• Can hide one file split across multiple carriers
• Hidden files cannot be accessed without a password
• Allows you to enter up to three passwords, making it harder for someone to crack (aka they must know all three passwords); if you don’t want to use all three passwords, you can use only one or two
• Can hide files as large as 256 MB
• Can hide a “decoy” file along with your main hidden file
  • When the password(s) for the decoy file is entered OpenPuff shoots out the decoy file and the password(s) for the main hidden file is entered OpenPuff shoots out the main hidden file. The idea here is you can give someone the password(s) for the decoy file if you are forced to reveal the password(s).
• When hiding a file inside carrier(s), uses four levels of security to ensure files are safe: encryption, scrambling, whitening, and encoding
• Can insert a hidden “mark” (i.e. text watermark) on carriers
• Has a built-in ability to “clean” carriers (i.e. remove hidden files from carriers)
• Makes it extremely hard for someone to accidentally unhide hidden files. Hidden files can only be extracted when: a) the password(s) are known b) the correct carrier is selected or carriers are selected in the right order, if multiple carriers were used and c) the same bit selection is used that was used when file being originally being hidden
• Aside from file size and date and time accessed, carriers remain untouched and work as normal. For example, if you use a carrier as an image then that carrier remains an image that you can view even after using it as a carrier
• Is portable and open-source

Cons

• Has a learning curve, although the curve isn’t too big — learned the program isn’t too difficult
• The method to unhide (i.e. need password(s), carrier(s) in same order, and correct bit selection) can make it a bit annoying for people to unhide files (e.g. if you forget what order the carriers were in or if you forget which bit selection you had used)
• Has an inherent limit on how many bytes of data one carrier can hold; this limit varies from carrier file to carrier file. Having this limit isn’t that big of an issue (it has to do with the way OpenPuff works and its enhanced security measures). What is an issue is there is no way of knowing how many bytes of data a specific carrier can hold until you actually load it into OpenPuff, which can make it annoying to find a large enough carrier to hold your hidden file
• Can only hide one file at a time; no batch processing is supported nor can you hide multiple files inside the same carrier
  • Note: You can get around the one-file-per-carrier(s) restriction by ZIPing or archiving the files you want to hide before throwing them in OpenPuff
• Would be nice to have more selection for carrier file types, such as ZIP or RAR
• When selecting carriers for hiding files, by default “All files” is enabled and you are shown all file types even though you cannot use all file types as carriers. This may result in you accidentally selecting an unsupported file type which will cause you go to back and select again. This can get annoying
• Cannot hide files larger than 256 MB
• Program window cannot be minimized or resized, only closed

Discussion

TrueCrypt is known and respected as one of the best, if not the best, encryption tools primarily due to how it goes above and beyond encryption — all the other features it has are what make TrueCrypt special, like plausible deniablility. Similarly, OpenPuff is an excellent steganography program not just because it can do steganography; there are tons of programs that can do steganography. Rather, OpenPuff is exemplary because it goes above and beyond steganography thanks features such as its multiple layers of protection, ability to use decoy files, ability to split one file across multiple carriers, portability (yep, doesn’t need to be installed), and more.

In fact, my two favorite features of OpenPuff are plausible deniability (the decoy feature) and its ability to split one hidden file across multiple carriers. These two features are awesome simply because they allow for added security that most other steganography programs lack. The other feature I like in OpenPuff is the fact that it uses four layers of protection to ensure your hidden files stay hidden until you unhide them with OpenPuff; OpenPuff encrypts, scrambles, whitens, and encodes all hidden files, making it extremely (extremely) hard for someone to gain access to your files without your password.

In terms of features, OpenPuff rocks. I cannot think of or find a steganography program that provides more security than OpenPuff. Where OpenPuff falls down is its usability.

You see OpenPuff has a butt-ugly interface and has options that are not necessarily self explanatory. It isn’t that the program is impossible to use or understand, but newbies to OpenPuff will definitely scratch their head asking themselves “what does this do” at multiple stages of the program; however, once you learn OpenPuff, it is a breeze.

When you first run the program, you can prompted with the main-program window that has the following options:

• Hide (hide a file)
• Unhide (unhide hidden file)
• Mark (add text watermark to carrier(s))
• UnMark (remove text watermark from carrier(s))
• CleanUp (remove hidden file from carrier(s))

When you go to Hide, you are prompted with the Data Hiding window in which you must specify five parameters:

• Password. By default you are asked by OpenPuff to enter three different passwords of minimum eight characters each, all of which must be used to unhide the file you are about to hide. If you don’t want to use three passwords, you can manually disable up to two of them so that you only use one password.
• File you want to hide. You can hide any file of any file format you want. You can only hide one file at a time — you cannot hide multiple files inside one carrier.
• Carriers. Carriers are the files that hold your hidden file. You can have one carrier or as many carriers as you want; if you use multiple carriers, your hidden file is split among the carriers and you can only unhide your file if you use all carriers. Not only that must it is important to remember the order of the carriers you have used because you must load the carriers in the exact same order when you go to unhide your file, otherwise you will not be able to unhide.
  • OpenPuff is unable to use all file types as carriers; there is a specific list of file types that can be used as carriers by OpenPuff: BMP, JPG, PNG, TGA, PCX, AIFF, MP3, NEXT/SUN, WAV, 3GP, FLV, MP4, MPG, SWF, VOB, and PDF.
  • It is important to note, because of the way OpenPuff works with its advanced security measures, each carrier can only hold a certain amount of data. This amount of data varies from file to file. OpenPuff tells you exactly how much data a carrier can hold once you load the carrier inside OpenPuff. There is a “Selected / Total” bar at the bottom of the program window that tells you how many bytes your carrier can hold (Selected) and how many it needs to hold your hidden file (Total). The bar is red if the carrier you selected is too small. If this is the case, you either need to pick a different carrier or use multiple carriers until the bar turns green.
• Bit selection. This is probably the most confusing of all things when hiding files. Bit selection has to do with behind-the-scenes algorithms OpenPuff uses. However, you don’t really need to worry about what OpenPuff is doing behind the scenes. Rather, you need to understand that via this setting, you can increase the amount of bits a carrier can hold. By default carriers are set to the Medium setting; if you want a carrier to hold more bytes, you can change up to Maximum. To change bit selection, you need to click on the option for the particular file type of carrier you are using. If you are using multiple different file types as carriers, you need to modify the setting for each file type.
  • It is important to remember what bit selection you use because you must select the same bit selection when unhiding files, otherwise you won’t be able to unhide files.
• (OPTIONAL) Decoy. OpenPuff has the ability to allow you to insert a “decoy” file. Like you set a password for your hidden file, you must select a password for your decoy file. Then, when you go to unhide your hidden file, if you enter the password for your hidden file then you are given your hidden file; if you enter the password for your decoy, then you are given the decoy file. The idea here is you can give someone the password for the decoy file if you are ever forced to reveal your password.

Once you are done with that, you hit the Hide Data button and OpenPuff hides your file inside the carrier(s) you selected. The whole process is a bit confusing at first but becomes second nature if you use the program often.

Overall, OpenPuff has its shortcomings but it is the best free steganography program I have ever used. Highly recommended.

Discussion

OurSecret is another very good steganography program. The best way I can describe OurSecret is by comparing it to OpenPuff; OurSecret is everything OpenPuff isn’t and is nothing that OpenPuff is. Confused? Let me explain.

OurSecret is extremely easy to use. You install the program, run it, select your carrier, select the file(s) you want to hide (you can hide any type of file), pick a password, and hide the file(s). It is as easy as that. OurSecret has no file size limit on the files you hide, you can hide multiple files inside one carrier, there is no size limit on how much data a carrier can hold (i.e. you can potentially hide a file inside a carrier that is larger than the carrier itself), and you can use any file type as a carrier; all these are features missing in/shortcomings of OpenPuff.

The tradeoff is OurSecret doesn’t provide all the enhanced security features like OpenPuff, such as four layers of protection, multiple carriers, multiple passwords, decoys, etc. The idea here is this: OurSecret is more user-friendly while OpenPuff is more secure. Which one you use depends on what you desire.

That said, there is one thing I want to point out. OurSecret is not portable, which is fine. What isn’t fine is the fact that it comes packed with crapware; I counted three crapware offers while installing OurSecret. And not only is there crapware but the crapware is the type that appear to be part of the installation of OurSecret and you must explicitly click ‘Decline’ to avoid them — they aren’t the avoid-by-unchecking-checkbox type. So be on the watch for that if you decide to grab OurSecret.

Xyz printing app crashes on mac computer. Go from concept to print seamlessly. Streamline your 3D printing workflow with XYZprinting's range of software tools for 3D design, scanning, and printing.

Overall, despite the crapware, OurSecret is a good option for people that want simple and straightforward steganography.

What is Steganography?

Steganography is the science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message.

An Example of Image Steganography ..

A perfectly innocuous picture? Nothing special about it? Well if you download QuickStego and copy the above image into the system, you will see that there is a lot of 'secret text' hidden in this image. Try it and see! Or if you can't wait, move further down this page for a screen shot of what will be revealed ..

QuickStego - Screenshots

Load the image from above into QuickStego (or QuickCrypto), and the secret text that was hidden in the photograph is revealed:

Download QuickStego Now - It's Free!

System Requirements & FAQ

* Operating System - Windows XP or Vista or 7.

* Display - 32 bit color depth required

* Image Types that can be opened - .jpg/.jpeg, .gif, or .bmp formats

* Saved Hidden Text Images - .bmp format only

* Approximately 2MB of free hard disk space (plus extra space for any images)

What does QuickStego let me do?

QuickStego lets you hide text in pictures so that only other users of QuickStego can retrieve and read the hidden secret messages. Once text is hidden in an image the saved picture is still a 'picture', it will load just like any other image and appear as it did before. The image can be saved, emailed, uploaded to the web (see the picture of the lady with a laptop above - this image has hidden text) as before, the only difference will be that it contains hidden text.

What does QuickStego NOT do?

QuickStego does not ENCRYPT the secret text message though it is well hidden in the image. If you require the message to also be encrypted (so even if found it can't be read without knowing a password) then QuickCrypto is the product for you. QuickCrypto includes the functions of QuickStego but also allows you to securely encrypt text and files and even hide files on your computer.

QuickStego will not let you hide files in images, to do that you require QuickCrypto. QuickCrypto can hide secret text and/or files in picture images.

Why is QuickStego free?

Quite honestly, QuickStego is provided free of charge as we hope you will like the software and wish at some point to upgrade to QuickCrypto or other Cybernescence products.

Given QuickStego is freeware, is it supported?

Yes, the core functions of QuickStego are also part of QuickCrypto, therefore the product will be supported for the foreseeable future. Functionality on its way, is the ability to hide messages inside audio files, e.g. mp3 and wav.

Tap and hold two fingers on the menu bar and up pops the app switcher. But to go backwards through the list of apps, you have to add the Shift key to the keyboard combo, which requires some awkward finger stretching on the user’s part.Swish’s solution?

How much text can be hidden in each picture?

The larger the image, the more text that can be concealed within. QuickStego will tell you how many characters of text you must lose if you go over this limit per picture. In practice a lot of secret text can be hidden in even a small image.

How does it work?

QuickStego imperceptibly alters the pixels (individual picture elements) of the image, encoding the secret text by adding small variations in color to the image. In practice, to the human eye, these small differences do not appear to change the image.

QuickStego was featured in PC Plus magazine as part of a series of articles (in editions 296 and 297) on Cryptography and Code-Breaking. The article in edition 297 highlights that software like QuickStego can complement Cryptography by hiding encrypted items in images to make them appear unworthy of interest from a cryptanalysis point of view.
