Steganography software for BMP images, based on blue LSB technique; includes cryptography + steganography. Created for the final research paper of high school (2018).
- Clone the repository
git clone https://github.com/brancaleon/stegomalignani.git - Compile with command
g++ -o StegoMalignani StegoMalignani.cpp EasyBMP.cpp - Begin to exchange secret messages with your friends
For hiding a message in an image, use:
./StegoMalignani -n targetImage.bmp
Type the secret text, then <end>
Type the key for encrypting the text
For revealing a message from an image, use:
./StegoMalignani -r targetImage.bmp
Type the key for encrypting the text
If the key is correct, you will get the secret message (with a wrong key, you will probably get a nonsense string)
-
Never reuse an image and don't allow in any way a comparison between original and edited image.
-
Choose strong encryption keys.
-
Compressing the image, you will lose the encoded content.
-
Try to exchange the image in not-suspect situations, usually posting the photo of your kitty should draw much attention.
It is a quite secure communication system if you are trying to hide something from your colleagues. Feel free to test or contribute to the project, keeping in mind that it is not suited for a professional context.
Don't trust this software if NSA or governments are tracking you. Go for something a bit more secure.
