The reverse turing test

I asked GPT-4 to come up with 10 questions to determine if the answerer was AI or human.

I provided my own answers for these questions and I also asked ChatGPT to answer them.

The result is that GPT-4 was able to correctly differentiate between AI and Human.

MD5 Collision with CRC32 Preimage

Here's the scenario: We want to craft two different messages with the same MD5 hash, and a specific CRC32 checksum, simultaneously.

In other words, we want an MD5 collision attack and a CRC32 preimage attack.

This might seem like a contrived scenario, but it's exactly the one I faced while producing my PNG hashquine (Yes OK maybe that's also a contrived scenario, cut me some slack).

On its own, a CRC32 preimage attack is trivial. You can craft a 4-byte suffix that gives any message a specific checksum, calculated using a closed-form expression (which I am too lazy to derive, not even with assistance from Z3). It's not an attack per-se, since CRC32 was never meant to be cryptograpically secure in the first place.

Pizza Recipe

Hi I'm Simone! This recipe was developed based on some tips I acquired over time from lots and lots of resources and tutorials like youtube videos, family and friends recipes. I'm just an amateur who likes making pizza :)

If you plan to perfectionate your pizza making skills, I suggest to come up with your own recipe and research online watching lots of tutorials and different techniques. For now the following recipe is the one that works for me!

(I'm not a professional pizzaiolo and I never had any sort of experience in a professional pizzeria restaurant)

When I put the reference implementation onto the website I needed to
put a software license on it.

And I looked at all the licenses that were available, and there were a lot
of them. And I decided that the one I liked the best was the MIT License,
which was a notice that you would put on your source and it would say,
"you're allowed to use this for any purpose you want, just leave the
notice in the source and don't sue me."
