🔓 Oh, look! Another #cryptography "wizard" from the ivory tower of academia thinks they can save the world by roasting #Kerberos tickets like marshmallows over a campfire 🔥. Matthew Green, emerging from the cryptographic crypt, offers 1,473 words of ego-stroking drivel about his resume while the rest of us wonder if the true #security threat is death by #boredom. 🥱

Thank you for embracing the #fediverse #mastodon

I am on the other side of the country in #HamOnt. Can you convince #MatthewGreen to jump on board.

One of the many interesting aspects of the new wave of artificial intelligence systems is that with them, copyright has moved from the fringe to centre stage. There are continuing debates about what role copyright should play in the world of generative AI, not to mention various lawsuits asking the courts to rule on that question. Those debates and lawsuits have been about two aspects of AI: […]

"The challenge in storing encrypted backup data is that strong encryption requires strong (or “high entropy”) cryptographic keys and passwords. Since most of us are terrible at selecting, let alone remembering strong passwords, this poses a challenging problem."

"Indeed, it no longer feels amusing to see the Telegram organization urge people away from default-encrypted messengers, while refusing to implement essential features that would widely encrypt their own users’ messages. In fact, it’s starting to feel a bit malicious."
