steganography-tool's Introduction

What is this?

A Steganography Web Application.

Supported Files

  • PNG
  • WAV

Development Setup

Both deployment setup have been tested on Debian 12. No guarantees it will work on other operating systems...

  1. Install Docker Engine with Docker Compose
  2. Create a enviornment variable file. touch .env.
  3. Fill in the enviornment variable file based on the example file, .env.example.
  4. docker-compose -f docker-compose-debug up
  5. Visit your webpage at localhost:4321.
  6. Your API endpoint should be running at localhost:8000

Perform Database Migrations

The database for the API endpoint will be empty initally:

  1. Give execution access to migration-helpers.sh.
  2. Run migration-helpers.sh

In the event that the script does not work (no output, error messages), consider running the commands in the shell script manually.

โš ๏ธ This was hacked together for a small university coursework. The codebase is messy and many things are hard-coded.
You have been warned.

steganography-tool's Issues

Center the image shown to be align with the header text

When uploading smaller images, the images are aligned towards the left, causing it to be mis-aligned from the header text.

Evidence

image

Expected

Image should be directly centered below the header text (Base Image and Encoded Image header text)

(Image) Encoding/Decoding fails if all bits are selected

To replicate

  1. Upload a png image.
  2. Select all bits for encoding
  3. Put any message/key.
  4. Encode
  5. Use encoded image as the base.
  6. Attempt to decode the image with the same key, with all selected bits.
  7. Decoding will fail. Showing random bytes instead of original message.
