Stuart-I think that the changes you have made to the page on the Affine Cipher are good. I like that you added the examples for encryption and decryption because it makes it much easier to understand how the cipher works. The only part of that section that I think is a bit confusing is why the numbers 5 and 8 are chosen for that formula. If you know why, maybe you could find a way to just explain that on the page. I also couldn't tell if you were the one who added the section on the weaknesses, but that section is good and should remain on the page. The only other information I would add to the page is maybe how the cipher first came about (who created it or when the cipher was first used) if you happen to know these details. ~Sam~ 123samantha (talk) 16:06, 12 April 2009 (UTC)
