# Large Language Models Cannot Break Symmetric Cryptography

A Hacker News discussion highlights that current large language models pose no real threat to symmetric encryption, such as AES. Despite their text-generation capabilities, they lack the mathematical reasoning needed to crack cryptographic keys. This reassures that core encryption standards remain secure against AI-powered attacks for now.
