[ARG] The Pizza Code Mystery

You just described decryption.

I’ve heard this tossed around a lot, but has anyone actually tried using the Benaloh cryptosystem, and then the Paillier cryptosystem?

The problem that we ran into, if I recall correctly was that we needed two large prime numbers as a key.

Decryption is where you already know the key. If you don’t know the key - then it’s called ‘code breaking’.

"Decryption is the process of converting encrypted data back into its original form, so it can be understood."

Decryption is very broad in scope. You do not have to know the key in order to decrypt something. The method commonly used for decrypting something without the key is called “brute forcing”, and not “code breaking”.

Actually the most common form of decryption is entering in the key… because you already know it. A bruteforce attack is not considered decryption at all. Why? Because the bruteforce attack is the process in which you use to FIND the key. Once you have the key, that’s when the decrypting beings.

Bruteforce, and dictionary ‘key-finding methods’ are known in cryptography as “Cryptanalysis’s Attacks”. Decryption has nothing to do with it.

Brute forcing is a method which you generate every combination of key that could decrypt the encrypted data. Cryptanalysis is a method used for analyzing encrypted data (who would have known) and attempt to learn information about the data.

Brute Force Attacks. Unlike hacks that focus on vulnerabilities in software, a Brute Force Attack aims at being the simplest kind of method to gain access to a site: it tries usernames and passwords, over and over again, until it gets in.”

Cryptanalysis refers to the study of ciphers, ciphertext, or cryptosystems (that is, to secret code systems) with a view to finding weaknesses in them that will permit retrieval of the plaintext from the ciphertext, without necessarily knowing the key or the algorithm.”

If you make the encrypted data readable, then you have decrypted it.

Why not take the semantics argument to a different forum? This forum is for solving the Pizza Code Mystery.

Did we ever try this?

Also you are right, we should work together not against each other.

Can Benaloh or Paillier be cracked (doesn’t matter how long it would take)?
Since “CIA couldn’t crack it”, and password for hex is BENALOHPAILLIER, it would seem pretty obvious to focus on those methods.
Unfortunately, I don’t know how to, and CryptTool 2.1 doesn’t have Benaloh. :confused:

A lot of the homophoric encryption methods seem to have not a lot of implementaions online.

Even the CrypTools don’t seem to support them. CrypTool 2 supports Paillier, but I can’t find anything for Benaloh. We would have to write a program to do it.

Already been written and posted. Unfortunately, I just don’t know how to run it

You guys still trying to figure out this?

I thought the thread was dead…oh well.

-sleeps-

someone wake me when we find something.

Was there anything that’s important to the ARG in Dr. Horn’s easter egg office in the canyons?

Don’t think so.
But if I remember correctly, there was pictures of air force base, IRC clue (one that gave cords).

Have we ever checked for stenograpy in Lies.jpg? Something about it just seems off.

Just checked and I found nothing.

How did you check? Because there is a corner of the image that appears to have been put over something else.

I’ve circled the spot where this happens:

EDIT: Just to clarify, the reason that it looks pasted over is that the edge of the word lies is cut off in a straight line, and in the upper right corner there are two black lines.
Lies.jpg

I checked for hidden images, and if the image matches up (in case part of it was photoshopped together). I do see what you mean, but it looks more like poor ms paint skills. It looks like it says lies, and I can’t think of any word that start with lies.
