• Resolve TODO 2 : Add auto detection of the name of file to be extracted in new_main funtion
• Auto name of extracted file is "[inputImage Name] [hideFile Name].[inputImage file format]"

I was planning to add the hidden file name along with the hidden file contents itself. Because the hidden file name may contain hint about the file contents. This was the rough plan: Add some magic bytes to the hidden data, then add the file name after those magic bytes, then add "0x0000" as a separator, and after that we can have the hidden file content.

Let me know if you are willing to implement this, else I will do this update

That's a good idea. I was misunderstand what you want to do. Now I'm completely understand and I want to implement it.

[priyansh-anand]

Sure, you can go ahead and implement that :)

Also, for the encrypted mode, encrypt the file name too
