Project description

Project AlexGyver on Python by TheK4n
\
Steganography encryption tool. It can hide text inside PNG image pixels. It uses AES or RSA encryption methods.
\
Design by Пашушка

Installation:

From AUR

yay -S image-crypt

Install by pacman (Recommended)

git clone https://github.com/TheK4n/image-crypt.git
cd image-crypt
makepkg -sic

Install from source

git clone https://github.com/TheK4n/image-crypt.git
cd image-crypt
make install

Usage

GUI:

image-crypt-qt

CLI:

image-crypt --help

Result:

usage: image-crypt [-h] (-e | -d) [-o OUTPUT] images [images ...]
Steganography encryption tool
positional arguments:
  images                path to image to encrypt of decrypt
optional arguments:
  -h, --help            show this help message and exit
  -e, --encrypt         encrypts text in image
  -d, --decrypt         decrypts text from image
  -o OUTPUT, --output OUTPUT
                        name of output image

\
For encryption:

image-crypt -e images/test.jpg

Result: saved image with default name image_encrypted.png

For decryption:

image-crypt -d test_encrypted.png

Result: decrypted text

\
Example:

echo "test message" | image-crypt -e image.png -o test_image.png
image-crypt -d test_image.png > res.txt

Docker:

Example:

docker run --rm -it -v $(pwd):/image-crypt -w /image-crypt thek4n/image-crypt image-crypt -e image.png

/image-crypt - Container`s directory\
thek4n/image-crypt - Image on DockerHub\
image-crypt - Program name\
image.png - Your image in your work directory

Enter the text, press Ctrl + d and enter the passphrase

Result: Encrypted image in work directory

FAQ

Q: What is the level of cryptographic strength?

A: It uses symmetric and asymmetric encryption methods such as AES and RSA.

Q: Does it pack the image data into text?

A: No, it’s packing text into image pixels.
