Et Tu, Brute?

The Story

This morning the mailman dropped off a mysterious package. You weren't expecting anything, but the box had labels that said "extremely fragile" and "live animal: biological specimen" and "do not agitate" on the outside, and it didn't have a return address. You decide to bring it inside, and carefully open it up, expecting spiders. Instead, you see a phone sitting on top of a pile of bubble wrap.

The phone rings.

You look around, then pick up the phone. It's the White Rabbit, wearing a fake moustache. "Hello agent, I hope you don't mind all the mystery, but these are special circumstances, and we can't let POOKIE find out that you're helping us! He might tamper with our communications, or worse, make a connection with your world and hire a motorcycle gang to find you and keep you from solving the puzzles."

You consider that last part. What, exactly, have you gotten yourself into?

The White Rabbit blinks at the screen. "Well... Don't worry to much about it! I promise the extra credit will be worth it. We're short on time so let's get started. Thanks for your help solving the first puzzle - POOKIE, the evil artificial intelligence that Bill the Lizard accidentally set loose on the world of Wonderland, stopped printing invisible money once we solved the problem, as promised. But now we have a bigger problem - and another puzzle."

Before the White Rabbit can continue, another, more shrill, voice in the background begins shouting things in an angry voice. The White Rabbit looks around nervously.

"I knew we never should have installed those smart lights! Or that smart refrigerator! Who needs a smart refrigerator anyway? Or the smart thermostat! It's freezing in here, where's my jacket? And don't even get me started about the smart toilet... Smart is stupid! That's how the world is these days!"

You almost ask what a smart toilet is, but instead you ask, "Who's that?"

The White Rabbit says, "Oh, that's the Mad Hatter! He's my boss, you see. He's the CEO of Mad Hatter Industries. I answer the phones - Mad Hatter Industries, how may I help yooooou! But anyway, back to the big problem. You see, POOKIE hacked our system, encrypted all our files, and took over all the smart gadgets in our office - the smart lights, the smart printer, the smart thermostat, everything. Now we have to solve POOKIE's puzzle, or be left in the dark forever."

There was a loud crash, and the Mad Hatter began cursing. "Can't see anything in here!"

"Okay, Mr. White Rabbit, just tell me what I need to do to help you."

"Excellent! I am sending the puzzle now. Once we get the lights back on, maybe you can meet the Mad Hatter. We have a very fine conference room, the finest in all of Wonderland."

You're not so sure that's a good idea, but you just nod.

The Mad Hatter was stumbling around, bumping into things. "Can't find my hat! Where's my hat? Where'd it go?"

"Have you checked your head, Mr. Hatter?" asked the White Rabbit. "Mr. Hatter really is a lovely person, you'll really like him very much," the White Rabbit to you.

"Sure," you say.

"Well, back to the problem - with our system hacked, and our smart appliances under the control of the evil POOKIE, we're defenseless. We can't even write Java code to try and solve POOKIE's puzzle. But maybe you can make some sense of the puzzle - I'll send it to you using the phone."

There was a sound of a parrot screeching in the background. "Well," said the White Rabbit, "I'd better go. Thanks for your help, and don't forget, the extra credit will show up in your account when you finish each puzzle!"

The call ends, and shortly after, POOKIE's next puzzle arrives in your mailbox. You peek out the window, checking for motorcycles or tattooed thugs, but don't see any. Well, time to get to work...

Solution

Can crack using spaces, or using brute force.

Token 1 (k=9):

Cryptology is the study of encoding an decoding messages as well as the mathematical foundations of cryptographic messages. The word cryptology originates from the Greek word kryptos meaning hidden.

Token 2 (k=11):

It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. Sherlock Holmes, A Scandal in Bohemia.

Token 3 (k=13):

If you are looking for a secret key, you have come to the right place. The secret key is the word kryptos. Enter the secret word in the puzzle two quiz on canvas.
