I am not sure what server does, but for that repo to work, server does not even need any steganography, as the it has a database.
On "create", it picks a random image, hashes it and stores (user-id, secret, text) in database
On "extract", it's opposite - accept image, hash, fetch from db.
All the API calls would work just the same, no cryptography of any kind needed.
- ersinesen 2y ago[author here] Indeed it may be so by looking outside as a black box. But, let me emphasize that there is no data stored in the backend database. Just user credentials and steganogprahy key. This key is crucial to extract data. Hidden data is stored only in the image. Without access to it, server cannot extract the hidden data.
