“In under half an hour, Claude discovered the origins of the NIST P-192, P-224, P-256, P-384 and P-521 seeds. None of them were the results of any hash algorithm at all, but rather the output of the C library’s lrand48 random-number generator, seeded with a Unix timestamp!”

Gorgeous. I wonder if the NSA employee who did this suffered a head injury or has been quietly giggling to themselves for the last quarter century.

The two people were Bob Reiter and Jerry Solinas. Jerry wrote in a 2015 email to Daniel Bernstein that he thought it was a hash of the passphrase. I corroborated that story with 4 people, including two ex-NSA folks off the record.

Everyone was wrong!

I wasn't able to reach Bob. He was working in private industry as of 2018, but never responded.

Kind of sus that they would spread a rumor that its a phrase. This isnt something I would forget, or confuse with a timestamp..

It's possible that this "phrase hash" method was used for a different case - like another, unrelated and possibly unreleased algorithm. And then it was confused for the one used for those curves.

Maybe that explanation covers the rest that wasn’t identified?

FTA: This work was conducted at Anthropic by [...], and Steve Weis.

I wonder how much time he spent on the video relative to the other stuff

A buddy did it with Claude, so zero time.

Oh I even saw your other posts in this thread but didn't recognize the name. So much for my research skills

▲thadt an hour ago | parent [-]

I mean, at least you didn’t spend the last 20 years hashing 2^51 sentences in your research.

Genuine question, how many days of your life have you had to spend on this particular tinfoil convention?

Video is meant as a joke, it’s common to edit the subtitles of this video to alternate ones

Tptacek is an expert in this field. I imagine he's had to spend a considerable amount of time explaining why ECDSA probably aren't nerfed.

That's one of the best executed implementations of that joke I've seen in years.

understanding Spanish throws it off, but this is hilarious either way. LOL

▲guelo 4 hours ago | parent [-]

I understand Spanish being from Latin America but for a long time I couldn't understand a single thing he said because of the Spaniard accent and crazy laughter, and I enjoyed the memes just fine. But then few years ago I watched it with the real subtitles and something clicked in my brain so now when I watch it I mostly understand him fine. But now the memes are ruined because it's hard to hear and read two speeches at the same time. Just an annecdote about our weird brains.

Just to add here that this guy doesn't have a "standard" Spanish accent. He was from Andalucía (I don't remember where exactly), a region rather known for its accent being difficult for even native speakers to understand.

Anyway after I moved to Andalucía I now can understand the story he tells, but I have to pay close attention!

Is this like what Downfall is like for Germans?
