Anthropic reproduces 1997 seed-generation path for P-256 curve
- —P-256 seed matched the 1,842nd lrand48 candidate from an Aug. 16, 1997 initialization
- —The 876th candidate also produced a valid curve; the choice of 1,842 is unexplained
- —Base-point generation for P-256 and other NSA curves remains unresolved
- —Anthropic published reproduction code; the ETH link is EIP-7951 and passkey wallets
Why it matters: The work explains the provenance of NSA standard parameters but is not an exploit: private keys and existing Ethereum wallets are unaffected.
