AES GCM mode vs AES-CBC — The Mode Decision That Is Breaking Production Security Right Now
AES GCM mode and AES-256-CBC are not equivalent choices — one gives you authenticated encryption by default, the other silently opens your stack to padding oracle attacks and ciphertext tampering. This technical breakdown covers the real differences, when CBC is a compliance liability, and exactly how to migrate to AES-256-GCM in production systems today.
