Claude Solves 25-Year NSA Cryptography Mystery in 30 Min

Why this matters

For twenty-five years, a question about the NSA's elliptic curves sat unresolved because the person who could answer it, Jerry Solinas, had died, and the rest of the cryptography community treated it as a problem requiring specialized human archaeology. Claude cleared it in under 30 minutes. That gap, decades of amateur sleuthing and a standing bounty versus half an hour of machine reasoning, is the real headline for anyone building with these models.

If an LLM can reconstruct a cryptographer's undocumented methodology from indirect evidence, the same capability applies to auditing your own codebase, your vendor's crypto implementation, or that legacy system nobody fully understands anymore. For founders, this is a preview of what "due diligence" looks like when AI can retroactively explain decisions nobody wrote down. For researchers, it's a reminder that provenance and documentation matter more, not less, once your work can be reverse-engineered on demand.

We'd be cautious about overreading one well-publicized case, but the pattern is worth tracking: mysteries that outlasted human patience are now solvable in a coffee break.
