Some of the flags we will use with Outguess are:ĭ: Specify the filename which contains a message that needs to be hidden.
To embed a confidential file using Outguess, you will need the file that you want to hide and a image file in which you want to hide the data. After that, the Outguess will be installed on your system. The system might prompt for confirmation with Y/n option, hit y and then Enter to confirm.
#Outguess orginial install#
Now install the Outguess as follows: $ sudo apt install outguess
#Outguess orginial update#
Open the Terminal and update the system’s repository index using the following command: $ sudo apt update With Outguess, you can also hide the confidential data inside of an image file. Outguess is also a Steganography command-line tool that lets secret information be inserted into the redundant bits of data sources. In case, you want to remove the Steghide from your system, run the following command in the Terminal: $ sudo apt remove steghide Method 2: Through the Outguess utility (command line) Enter the passphrase and your confidential file will be extracted from the image file. The system will ask for the passphrase you have set while embedding the file into the image file. When you need to extract the confidential file from the image file, use the following syntax: $ steghide extract –sf image.jpgĮxample: $ Steghide extract –sf sample.jpg Now we can only keep the image file “sample.jpg” while deleting the confidential file, that is the “testfile” in our example. If you do not want to set a paraphrase for embedding, just hit Enter twice. This paraphrase will be used when you need to extract or decrypt the file. Then enter the paraphrase twice for embedding the file. AdvertisementĮxample: $ steghide embed –ef ~/Documents/testfile –cf sample.jpg Alternatively, you can also mention the complete path to the file instead of navigating to the directory. So will first navigate to the ~/Documents directory and then run the embed command. In our example, the file named “testfile” is in ~/Documents directory and we want to embed it into the “sample.jpg” image file. The syntax to embed a file into a JPEG format is: $ steghide embed -ef -cf It supports embedding the file into WAV, JPEG, AU, BMP formats. To hide a confidential file using Steghide embed feature, you will need the file that you want to hide and an image or audio file in which you want to hide the data.
After that, the Steghide will be installed on your system. The system might prompt for confirmation with Y/n option, hit y, and then Enter to confirm. Then install Steghide using the apt command as follows: $ sudo apt install steghide Update the system’s repository index using the following command: $ sudo apt update From the results, click on the Terminal icon to open. Then search for the Terminal application by typing the relevant keyword in the search bar. Go to the Activities tab in the top left corner of your desktop.
Method 1: Through the Steghide utility (command line) Steghide Installationįirst, launch the Terminal in your OS. Note that we have done the procedure mentioned in this article on a Debian 10 system.
#Outguess orginial how to#
In this article, we will explain how to hide the confidential files in an ordinary image file using various tools (including the command line and the GUI). On the other hand, an encrypted file also generates curiosity in the viewers. Why Steganography?Īlthough steganography is not as secure as encryption, it has several other advantages, such as the fact that no one will notice it because the embedded file looks like an ordinary file. The cover file in which you want to hide the confidential data can be a text, picture, audio or any video file. It is also useful if you want to send confidential data to someone without compromising security. In steganography, the confidential data is embedded in a camouflage file in such a way that no one but the sender and recipient can suspect the existence of confidential information in it. But today we are going to talk about another method, namely steganography, which makes it possible to hide the existence of secret data in order to keep communications private. However, one way to achieve this is through encryption. Sometimes we have to hide our data to protect it from third-party access to the system.
