Anthropic's AI model, Claude, has cracked a 25-year-old digital mystery from the U.S. National Security Agency (NSA), discovering that encrypted numbers provided by the agency in the 1990s were not hidden backdoors but came from a common random number program using 1997-1998 timestamps. The model solved a problem that cryptographers had pursued for 25 years in just half an hour.

Bitcoin's encryption curve (secp256k1) is unrelated to this, and its quantum computing threat remains unresolved.
