Anthropics' Claude cracks a 25-year-old NSA cryptography mystery in under 30 minutes

Anthropic's Claude solved a 25-year-old cryptography puzzle in under 30 minutes, determining that the unexplained seeds behind NIST's standard curves for digital signatures were generated by "lrand48," a simple C random number generator. The seeds had been supplied by the NSA without explanation, fueling long-standing suspicion of built-in backdoors; the finding makes deliberate backdoors far less likely.
