STEP 7: To hide the message type python LSBSteg.py -i "your image in which you want to hide your messge" -o "output of the image file with the format" -f "text file which you want to hide". ![]() #How to reveal hidden messages in image files installSTEP 6: Install the dependencies by typing pip install -r requirements.txt. STEP 5: Now type got clone and move into this directory. STEP 4: I will upload this encrypted message to some hosting server and then copy the downloadable link to hide it in our image. STEP 3: It will ask for password so enter your desire password. ( I am using CAST 128 cipher for encryption.) STEP 2: We will encrypt our message with symmetric key algorithm using gpg so that both the sender and receiver will only need a single key for encryption and decryption. So first we will create our secret key, for this i will open nano (you can use whatever you want ) by typing nano file.txt then press return and then i will enter my secret key then exit. STEP 1: Before hiding our secret message we will make sure to make it fully encrypted so if someone extracted the message from the image he would not able to get the secret message. By modifying only the first most right bit of an image we can insert our secret message and it also make the picture unnoticeable, but if our message is too large it will start modifying the second right most bit and so on and an attacker can notice the changes in picture. LSB-Steganography is a steganography technique in which we hide messages inside an image by replacing Least significant bit of image with the bits of message to be hidden. For example in binary number 10010010, "0" is the least significant bit. Least Significant bit also called RightMost Bit is a lowest bit of a binary number. So here I am going to use LSB-Steganography method to hide our message inside an image. We will use every possible methods to make our message hidden from any third person. Imagine a scenario where we want to send a confidential message and don't want anyone except the recipient to read it.
