I have got a custom.dll which is utilized in a larger application. The application executable imports this dll to use its functionality. But this functionality is not used through out the life cycle of the application but only when a specific event occurs. for instance when I input something in the application console a new thread would be created and some of the functionality of the given dll would be used. Now the problem is I am unable to find out what is exactly going on in the dll without having that application executable. I only have the dll file. I want to reverse it. Just like debugging an exe file and go through the registers step by step to find out what is what and why something happens, simply perform a dynamic analysis on the dll instead of the static one.
To be more specific, the dll file creates a specific string, I want to know how that string is created and where it is stored for console usage.
