GoKawiilAmateurs use AI models to crack decades-old Enigma-era ciphers
Non-expert enthusiasts, including a product development coach named Carter Leffen, are using large language models such as GPT-6 Astra to decode historical encrypted messages, including a German army Enigma cipher that had remained unsolved for 85 years. The AI systems deploy decryption algorithms and search online for supporting historical records, allowing users without cryptography training to attempt and sometimes succeed at codebreaking tasks.
