faiqsohail/securestego repository overview

⁠SecureStego

SecureStego is a command-line steganography tool that uses AES-256 encryption to securely hide and extract sensitive data within images. This tool can encrypt and decrypt data, ensuring that your hidden messages remain confidential.

⁠Features

• AES-256 encryption for secure data hiding
• Supports both PNG and JPEG image formats
• Data integrity check with hash verification
• Dockerized for easy portability

⁠Getting Started

You can easily pull and use the SecureStego Docker image from Docker Hub.

⁠Pull the Docker Image

docker pull faiqsohail/securestego:latest

⁠Running SecureStego with Docker

⁠Encryption (Hide Data in Image)

docker run --rm -it -v $(pwd):/app faiqsohail/securestego:latest -mode=encrypt -image=/app/<image.png> -data=/app/<secret.txt> -out=/app/<stego.png>

Replace:

• <image.png>: Path to the image in which the data will be hidden.
• <secret.txt>: Path to the file containing the data to hide.
• <stego.png>: Path to the output image with hidden data.

⁠Decryption (Extract Data from Image)

docker run --rm -it -v $(pwd):/app faiqsohail/securestego:latest -mode=decrypt -image=/app/<stego.png> -out=/app/<recovered.txt>

Replace:

• <stego.png>: Path to the image that contains hidden data.
• <recovered.txt>: Path where the extracted data will be saved.

⁠Example

docker run --rm -it -v $(pwd):/app faiqsohail/securestego:latest -mode=encrypt -image=/app/sample.png -data=/app/secret.txt -out=/app/stego.png

This command will hide the contents of secret.txt inside sample.png, producing stego.png. You will be prompted for a password.

Note: sample.png and secret.txt will need to exist in the current working directory where the docker command is ran from.

⁠Helpers for SecureStego

To make running the SecureStego Docker container easier, you can add the following helper functions to your shell configuration (.bashrc or .zshrc):

# Helpers for SecureStego
securestego_encrypt() {
  docker run --rm -it -v "$(pwd)":/app faiqsohail/securestego:latest \
  -mode=encrypt -image="/app/$1" -data="/app/$2" -out="/app/$3"
}
securestego_decrypt() {
  docker run --rm -it -v "$(pwd)":/app faiqsohail/securestego:latest \
  -mode=decrypt -image="/app/$1" -out="/app/$2"
}

Once added, you can use securestego_encrypt and securestego_decrypt commands directly from the terminal.

⁠Example with the helpers

To encrypt:

securestego_encrypt <input.png> <secret.txt> <output.png>

To decrypt:

securestego_decrypt <output.png> <recovered.txt>
