An Anthropic research model named Claude solved a decades-old cryptographic mystery by discovering the exact origins of the seed parameters used in NIST's ECDSA standard curves. Claude deduced that the seeds were generated using a 1990s C library pseudorandom number generator (`lrand48`) initialized by simple Unix timestamps. This finding dispels long-standing conspiracy theories about potential backdoors, confirming that the widely used cryptographic standards were created benignly rather than maliciously.
