For the module "Vertiefung Soziale Medien und Informationssysteme" at Leuphana university during 2020 I had the opportunity to research further into steganography and more creative approaches on encryption.

Steganography is a very interesting topic as there area many ways on how to achieve hiding information in plain sight. Also the concept of not urgently needing to encrypt data to hide it but to make questioning if it is even there in the first place a potential better approach really makes one think about all the use cases and possibilities of this still niche subject.

Thus during my research on the topic I stumbled upon Peter Eigenschink's JavaScript implementation of Steganography.js. After some backtalk to my lecturer I thought it would be a great chance to create a little modern website offering steganographic functionality like hiding text in images for the web while also gaining further insights during the usage of his implementation.

To get this project running I used Create-React-App for bootstrapping and Tailwindcss for dealing with layout pretty fast.

Working with the inputs for the steganographic functions made the implementation a bit difficult for me as either my drag-and-drop file library or the steganography.js library ran into many errors due to asynchronity of file deliverance. The latter works with the HTML5 canvas element and after spending some good hours on the project my approach was to at least drop the drag-and-drop functionality for the original file upload for encoding, but keep it for decoding still available which works now.

A video covering deeper research on the topic of steganography will soon be embedded into the website instead of a piano playing cat.

• Third Party scripts without package managers like npm or yarn can be added to React with the postscribe package. But they have to be attached after the DOM has been rendered so the order when postscribe is invoked matters and should be after React has built the site.
• In this project Tailwind was added with different start scripts so that running the project locally the whole css is available but when beeing deployed in production the css will get purged and file sized reduced dramatically.
• Third Party packages not available to npm or yarn can be imported as the javascript file directly in the src/ folder. In the first line of the package /* eslint-disable */ has to be added so that ESLint doesn't try to compile it on React startup. Then the package can be normally imported and functions can be called in ComponentDidUpdate().sdsa
