‘Wow, it’s a real discovery’: Claude cracks a 25-year NSA number mystery — Live Feedhttps://www.live-feeds.com/feed/wow-it-s-a-real-discovery-claude-cracks-a-25-year-nsa-number-mysteryContinuously updated, source-cited coverage. Claude AI identifies origin of 25-year-old NSA cryptography seedshttps://www.live-feeds.com/feed/wow-it-s-a-real-discovery-claude-cracks-a-25-year-nsa-number-mysteryhttps://www.live-feeds.com/feed/wow-it-s-a-real-discovery-claude-cracks-a-25-year-nsa-number-mystery#u138709Tue, 20 Oct 2026 05:52:08 +0000An internal research model from Anthropic solved a 25-year-old cryptography mystery in under 30 minutes. Claude traced five elliptic curve seeds supplied by the NSA for NIST digital signature standards back to lrand48, a simple C random number generator from the 1990s. This discovery suggests the seeds were generated by a standard process rather than being carefully crafted to include hidden backdoors, addressing long-standing suspicions among security researchers regarding the integrity of these widely adopted security standards.Why it mattersThe NSA provided these seeds without explanation,
