These ciphers will be difficult to, well, decipher.

If You Can Crack 5/7 Of These Secret Codes, You're A Secret Agent

The [A1Z26 cipher](https://planetcalc.com/4884/) replaces each letter with its place in the alphabet, so A is replaced with 1 (since it's the first letter of the alphabet), B is replaced with 2, and so on.

"This code replaces letters with numbers."

What does this secret message say?

This code uses the [ROT13 substitution cipher](https://en.wikipedia.org/wiki/ROT13), in which each letter of the alphabet is rotated 13 steps.

"This is a simple substitution cipher."

Now try this code:

Also called the masonic cipher, Freemason's cipher, Napoleon cipher, and tic-tac-toe cipher, the [pigpen cipher](https://en.wikipedia.org/wiki/Pigpen_cipher) replaces letters of the alphabet with shapes that are part of a grid.

"This one is the pigpen cipher."

What does this say?

This code uses the [Caesar cipher](https://en.wikipedia.org/wiki/Caesar_cipher), the code that Julius Caesar used to encode his messages. He simply replaced each letter with the one three spots ahead.

"I don't think you're ready for this jelly."

Give this code a try:

For this substitution cipher, the alphabet is rearranged randomly instead of in a set pattern.

"I like big butts and I cannot lie."

What about this one?

This was a combination cipher, first using the Caesar cipher (where each letter is replaced with the letter three steps away) and then putting the resulting code through the A1Z26 cIpher (where every letter is replaced by the number of its order of the alphabet).

"Apple bottom jeans, boots with the fur, the whole club was looking at her."

Can you decipher this message?

(There's a hint to solving this one if you look carefully.)

This code uses the [columnar transposition cipher](https://en.wikipedia.org/wiki/Transposition_cipher#Columnar_transposition), where using the keyword "CODES" (see it in all caps above the message?), each letter of the message is written in rows underneath. The letters are then read out from top to bottom in a chosen order. In this case, the order is the alphabetical order of the keyword, so the letters under the C are read first, then the letters under the D, then E, then O, and then S.

"She had dumps like a truck, truck, truck."

And finally, can you solve this one better than all the other CODES?

Sorry, bud. Your code-cracking skills are pretty lacking, and you're probably not going to join the CIA anytime soon. But hey, ignorance is bliss, right?

You've got some okay code-cracking abilities, but you've still got a little to learn before you can really go undercover. But keep practicing and one day you could be the world's greatest spy.

You're obviously a secret agent with those code-cracking skills. Jack Bauer should recruit you to help save the world.

You're code cracking wizard! You're a better secret agent than James Bond, Sydney Bristow, and Ethan Hunt combined. Nothing gets past you!
