Well, Vigenère is truly loved here, so I made a challenge too.

Hah! Dang you are fast! 6 minutes from post to crack, and you couldn't have gotten it IMMEDIATLY upon post... Incredible!

I'm certain it will take me longer than 6 minutes!

I looked at it on the screen long enough to convince myself that I had found N * the key length for low N. After that, it's basically housekeeping, which was fun the first couple of times but would pall a third time. I really should write a program to do this!

I still remember the look on - was it Revelation's? - face when I cracked Donald's first Vigenere by hand. All those astonished little 0s and 1s, glowing orange in his Jawa hood... priceless.

Yeah, Vigenere is so much easier to crack than even a monoalphabetic substitution if you have sufficient text. I just use a program to get the key length, and another one to score the possible key values based on how many SENORITA letters they yield. Even if I do them by hand, it is mostly just tedium, it doesn't really require any analysis or guess work.

I was thinking about posting a playfair challenge. I have a good bit of trouble with those.

Well, I thought this wouldn't last long. I use my own application to crack Vigenère. I still think it's handy :)
