P-256 seed: Claude reveals its origins in a clock

The seed of P-256, a key curve for digital signatures, had an unknown origin. Anthropic says Claude reconstructed how it was generated: with lrand48 and a timestamp from 1997.

The finding reproduces the 160 bits of the published seed, but it does not reveal an attack or demonstrate a weakness in ECDSA. We explore what Claude discovered about P-256 and other cryptographic curves, which historical questions remain open, and why a public seed is not the same as the secret keys used for a signature.
