GPT-6 Astra cracks 1809 Napoleon cipher, Claude audits NSA curves

AI engineer Carter Church used OpenAI's GPT-6 Astra to decode an 1809 letter detailing Napoleonic troop positions in six hours instead of weeks of manual work. Separately, an internal Anthropic Claude model traced the origins of five NSA elliptic curve seeds in under 30 minutes and found no backdoors.

• GPT-6 Astra decoded the 1809 military cipher in six hours
• Patent engineer Satoshi Tomokiyo verified the result
• Claude checked five NSA elliptic curve seeds in 30 minutes
• No weaknesses or backdoors were found in the NSA curves
