For P-256, the timestamp corresponds to August 16, 1997. The program extracted twenty-byte candidates; candidate number 1842 matches the seed published in the standard. It is more than a visual resemblance: it reproduces all 160 bits. Anthropic says Claude took less than half an hour to find the origin

For P-256, the timestamp corresponds to August 16, 1997. The program extracted twenty-byte candidates; candidate number 1842 matches the seed published in the standard. It is more than a visual resemblance: it reproduces all 160 bits. Anthropic says Claude took less than half an hour to find the origin of the five NIST seeds for curves over prime fields: P-192, P-224, P-256, P-384, and P-521.
