AES-128 drops to ~64-bit effective security. AES-256 stays at ~128-bit. The fix is one config line — but every place stores cipher state, you need to find. grover aes symmetric migration key-size https://qbit404.com/en/news/nist-pqc-suite https://qbit404.com/en/news/nist-pqc-suite Tue, 02 Jun 2026 00:00:00 +0000 noreply@qbit404.com (Mara Chen) Four years after the round-3 finalists were named, the standards are signed.
