Introduction

From ever since I was a little kid, I liked solving puzzles...including, Jig Saw puzzles/and, word game puzzles: Find the word/-etc. I also liked making words out of random letters: A,N,D = A, AN, DAN, -etc. I enjoyed writing poems...getting lines to rhyme. Then, when I grew up, and, learned about computer programming; I also learned about cryptography.

My own ability level, though, has never been expert; mainly, because the ability to produce really good Cryptography is to do with having learned maths...-(unless, of course, you have a program which does all of the Cryptography work for you)-; and, I was never very good at maths, I'm afraid; instead, all I ever learned was merely basic beginners maths, namely, how to: add/subtract/multiply/divide...; but, apart from having learned to recite by heart the 12 x Tables...that's about as far as I ever really got.
