Transparent data encryption in Azure SQL Database now supports AES keys (Public Preview) (opens in new tab)

For teams thinking about long-term cryptographic resilience, this preview is especially relevant. TDE with customer-managed keys has traditionally used asymmetric RSA-based key protectors, while broader industry guidance is increasingly focused on preparing for a post-quantum cryptographic (PQC) future and adopting cryptographic approaches that are better aligned with that transition. This update aligns with broader security guidance, including the NSA’s CNSA 2.0 recommendations, which emphas...
