The NIST elliptic curves seeds bounty has been claimed
The seeds behind NIST's P-192 through P-521 curves, which the NSA supplied in the late '90s with no explanation and which were long rumored to be hashes of a joke sentence, turn out to be plain drand48 output seeded with 1997–98 Unix timestamps. An Anthropic team found it with an internal model in under half an hour. Valsorda reimplemented the search in Go to confirm it, and the team donated his tripled $36,864 bounty to Let's Encrypt's nonprofit, ISRG.
