Claude reportedly traces origins of NIST elliptic curve seeds in under half an hour

Anthropic says Claude identified how five NIST standard elliptic curve seeds were likely generated, a question unresolved for over 20 years. Claude proposed the seeds came from the lrand48 generator seeded by Unix timestamps from 1997 to 1998, and the P-256 seed matches an August 16, 1997 start time. Some gaps remain, including the B-163 seed and skipped candidate curves.
