Thanks for the easy read. Question though: when we get to the input data and hashing algorithm, those numbers don't have to be clean, right? In your example, you used 9,437 and 319 - but these could be values like 9437.139 and 319.005385235808, right? That would make the system a lot stronger in my opinion and literally infinitely harder to find the original input value. Great post and thanks for sharing!
