I have thought about this before, that is why I wrote "inspired by Kasiski's Test" in the description.
Actually, I found the terminology rather unclear, in the literature I used, and in Wikipedia's article, too, concerning which part of it is still "the method/test" and which part goes beyond it. On Wikipedia (http://en.wikipedia.org/wiki/Kasiski_examination#A_string_based_attack), point 3 - 5 are concerned with the function to implement here, so I thought it would be reasonable to name it accordingly.

Do you have another source which is more clear about it?
What change in the description/title would you suggest?
