NIST Elliptic Curves Seeds Bounty
Some of the backstory here (it's the funniest fucking backstory ever): it's lately been circulating --- though I think this may have been somewhat common knowledge among practitioners, though definitely not to me --- that the "random" seeds for the NIST P-curves, generated in the 1990s by Jerry Solinas at NSA, were simply SHA1 hashes of some variation of the string "Give Jerry a raise".At the time, the "pass a string through SHA1" thing was meant to increase confidence in the curve seeds; the idea was that SHA1 would destroy any possible structure in the seed, so NSA couldn't have selected a deliberately weak seed. Of course, NIST/NSA then set about destroying its reputation in the 2000's, and this explanation wasn't nearly enough to quell conspiracy theories.But when Jerry Solinas went back to reconstruct the seeds, so NIST could demonstrate that the seeds really were benign, he found that he'd forgotten the string he used!If you're a true conspiracist, you're certain nobody is going to find a string that generates any of these seeds. On the flip side, if anyone does find them, that'll be a pretty devastating blow to the theory that the NIST P-curves were maliciously generated --- even for people totally unfamiliar with basic curve math.So: pretty fun bounty.
