Always Encrypted

SQL Server 2019 includes Always Encrypted, an encryption technology first introduced in SQL Server 2016 which allows clients to encrypt sensitive data inside client applications with the key benefit of never revealing the encryption keys to the database engine.

When using Always Encrypted, data never appears in plain text when querying it, and it is not even exposed in plain text in the memory of the SQL Server process. Only client applications that have access to the relevant keys can see the data. This feature is ideal for protecting data from even highly privileged users such as database administrators and system administrators. It does not prevent them from administrating the servers, but it does prevent them from viewing highly sensitive data such as bank account details.

Algorithm types

Always Encrypted uses the AEAD_AES_256_CBC_HMAC_SHA_256 algorithm. There are two variations: deterministic and randomized. The deterministic encryption always generates...
