Ah, yes, the thrill of downgrading from modern cryptographic marvels to hash functions that even your toaster would mock. 🤦‍♂️ Why settle for the robust #security of SHA256 when you can embrace the "cheapest, stupidest" algorithms that even a toddler could outsmart? 🙃🔐

Simplest hash functions

What came to your mind when you read “hash functions” in the title? If you’re pragmatic, you probably remembered SHA-256 or MD5. Those are cryptographic hash functions, and they work fast and well for arbitrary inputs, even if they are supplied by malicious actors. Or at least they’re designed to. That’s the exact opposite of what I want to talk about. I want to talk about the cheapest, stupidest, most ridiculous hash functions you can get away with.

[A] new paper [...] demonstrates a method for tricking a commercially available proof system into certifying false statements, even though the system is demonstrably secure if you accept the random oracle model."

Behold, yet another 🚀 "groundbreaking" #intro to #cryptography, assuming every #programmer lives and breathes only this – because who needs a #life outside of #SSL and hash functions? 🤓 Spoiler alert: mastering the art of exploiting cryptographic flaws will definitely make you the life of the party! 🎉

🎨🤓 Ah yes, because nothing screams "fun weekend project" quite like getting excited over math equations with coordinates and colors. Who knew hash functions could be so thrillingly intricate and *aesthetically pleasing*? But hey, if your idea of a good time is deciphering cryptic predicates, Doug's playground is your amusement park! 🧩🎢

@theZacAttacks No problem! Let me know what you think and share if you dig it!

I think crypto is the future now, whether we like it or not.
