- 6Hacker News·10/16/2026researchClaude Traces NIST ECDSA Curve Seed Origins
Anthropic says Claude identified how the seed values for several NIST ECDSA curves were generated: from the C library lrand48 pseudo-random generator seeded with Unix timestamps, not from a hash of a hidden phrase. The finding closes a long-running community question about the provenance of the P-192, P-224, P-256, P-384, and P-521 curve parameters and does not indicate a cryptographic break.
