GoKawiilAI models help amateur cryptographers crack historical ciphers, Nature reports
Nature's daily briefing describes how hobbyist codebreakers are using AI tools, including OpenAI's GPT-6 Astra, to solve historical encrypted messages, such as WWII-era German military ciphers. One user reportedly used the model to find a key to an unsolved 1809 cipher in about six hours. Cryptography experts say the surge of interest is welcome but has also led to a flood of requests to verify AI-generated solutions, some of which turn out to be wrong.
GoKawiil's interpretation of the reporting above, not reported fact.
The report suggests AI could meaningfully lower the barrier to historical cryptanalysis, letting non-specialists tackle problems once reserved for trained experts. It also hints at a emerging strain on expert communities, who must now spend time vetting a growing volume of AI-assisted claims, some of which may be false positives.
- Amateur cryptographers are using AI models like GPT-6 Astra to attempt historical cipher-cracking.
- One user reportedly solved an unsolved 1809 cipher key in about six hours using AI.
- Experts welcome the interest but are strained by requests to validate AI solutions that are sometimes incorrect.
