New: Encrypt a string into an already existing image using Stegodon (a C# library built for this project) and high-bit AES encryption.

Crack: Decrypt any message that was injected through this app.

Gen: Insert Stable Diffusion prompt, insert the string you want to encrypt, and save your one-of-a-kind password holder.

IF YOU RECEIVE THE BAD REQUEST ERROR YOU ARE USING AN OUTDATED VERSION OF THE PROGRAM. Download the latest build to fix this issue here This error is made because HF had a token breach and a lot of existing tokens were deleted. This new version has a new token.

Gen HTTP Request: Gen utilizes an HTTP request to fetch from an API, which can fail when loading the service initially. Restart the application a few times until you establish a connection. We are actively working on fixing this in the next patch series.
