AI Cracks 217-Year-Old Napoleonic Cipher in Six Hours

Carter Church, a cybersecurity engineer at SentinelOne, used OpenAI's GPT-6 Astra model to decipher an 1809 military letter in six hours. The document, originally encrypted by Eugène de Beauharnais on Napoleon's orders, had remained unsolved for over two centuries. The AI transcribed the image, analyzed the homophonic substitution cypher, and cross-referenced historical records to reveal troop positions. Church published the full research record on September 18, 2026, allowing independent verification. The decoded text provides details on Bavarian, Polish, and French forces, confirming the document's date as late March 1809, shortly before the Austrian offensive.

AI Decodes 1809 Napoleonic Cipher in Six Hours, Revealing Lost Military Briefing

Carter Church, an AI engineer at SentinelOne, used OpenAI’s GPT-6 Astra to decode a 217-year-old encrypted letter from 1809. The AI transcribed 1,300 symbols from a scanned image in six hours, revealing a military briefing sent to General Auguste de Marmont. The decoded text details troop positions and completes a sentence from Napoleon’s memoir, marking a significant application of AI in historical research.

AI Decodes Napoleon's 1809 Cipher in Six Hours

Carter Church, a cybersecurity engineer, used OpenAI's GPT-6 Astra to decipher a coded military letter from 1809 in six hours. The letter, sent by Napoleon's stepson to General Marmont, outlined troop positions and urged the general not to be intimidated by his isolation. Church published the solution and code on September 18, 2026, allowing others to verify the result. The decipherment confirms the letter's date and content, which had been lost for 217 years.

AI Decodes 217-Year-Old Napoleonic Cipher in Six Hours

Carter Church used OpenAI's GPT-6 Astra to decode a 1809 cipher letter sent to Napoleon's marshal Auguste de Marmont. The AI transcribed 1,300 symbols from a 1969 journal scan in six hours, revealing military troop movements before the Austrian invasion. Church released the key and script for verification, though some historical details remain debated.

Apple debuts cryptographic photo authentication with iPhone 18 Pro

Apple revealed Apple Reference Image, a camera feature on the iPhone 18 Pro that signs captured pixel data and metadata to produce a tamper-evident 'digital negative' processed in Private Cloud Compute. The system binds the camera sensor to the Secure Enclave, signs data at capture, timestamps it, and uses cryptographic verification (RSA-3072 and ML-DSA-87) with a revocation mechanism to flag compromised sensors, enabling verifiable authenticity for photos.

AI-Fueled Duel: Simultaneous Proofs Spark Credit Questions in Cryptography

Two independent teams used OpenAI’s GPT-5.6 Sol Ultra to tackle the same open problem in unclonable encryption, submitting arXiv preprints within about three hours of each other: MIT’s Seyoon Ragavan via a hands‑on, multi‑agent workflow, and Ananth with Amit Sahai using a bespoke UCLA system to pursue and critique the solution. The near‑simultaneous results raise questions about independent discovery and how credit is attributed in AI‑augmented research, though neither paper is peer‑reviewed yet.

Cryptology: from war codes to modern digital encryption

Cryptology is the study of secret codes, encompassing both cryptography (creating codes) and cryptanalysis (breaking them). While historically linked to spy networks, cryptology today also refers to computer algorithms that encrypt data to protect passwords and personal information, with World War II code talkers highlighted as an example of its use in practice.

Reticulum Targets a Radio-Driven Post-Internet Network

Hackaday reports on The Tech Prepper's demonstration of Reticulum, a decentralized cryptographic network stack, using high-frequency radio to envision a post‑Internet communications layer that could operate when traditional networks fail; encryption bans on ham bands complicate real-world use, but the setup shows connecting a PC to an open-source radio modem and SDR tools, with BBS-style options like modem73 as possible alternatives. While appealing to survivalists and cyberpunk hobbyists, practical mass deployment faces regulatory and technical barriers.

Quantum Basics: From Spooky Action to a New Computing Era

A plain‑language primer on quantum ideas: at tiny scales particles can be in superpositions and only take a definite state when measured, while entangled particles remain linked across distances. These quirks enable qubits that can encode many possibilities in parallel, potentially solving problems in drug design, materials science and cryptography far faster than classical computers. Real-world quantum tech is still fragile and not a substitute for everyday tasks; nonetheless, progress raises both exciting capabilities and security/ethical questions as encryption faces new risks and quantum‑safe networks develop.

Microsoft’s Majorana 2 promises 1,000x reliability, edging quantum era forward

Microsoft unveiled Majorana 2, a topological quantum chip the company says is 1,000 times more reliable than Majorana 1, with qubits lasting up to a minute. AI-driven research and manufacturing acceleration helped speed development, pushing toward scalable quantum computing by 2029. The story also notes rising crypto concerns, as advances in quantum tech threaten Bitcoin’s cryptography and Citi warns practical quantum attacks could arrive sooner than expected.

Quantum Entanglement Delivers Certifiably Perfect Randomness

ETH Zurich researchers used a Bell-test experiment with entangled qubits separated by 30 meters and performed over a billion trials in about nine hours to demonstrate randomness amplification that transforms imperfect randomness into certifiably perfect randomness, a device-independent result that could underpin future cryptography and security systems. The work, published in Nature 2026, shows randomness that remains truly unpredictable under rigorous analysis, surpassing previous RNGs that depended on trusted hardware.
