To execute a query on encrypted database columns, insert data into these columns, retrieve plaintext values, or perform supported operations (such as point lookup searches) using deterministic encryption, the user or application issuing the query must fulfill the following prerequisites:
Nota
If the user has required database permissions to read the data, but no access to the keys protecting it, the user can still retrieve cyphertext (encrypted) data by connecting to the database without enabling Always Encrypted in the database connection.
Here's how queries on encrypted columns work:
A client driver interacts with a key store, containing a column master key, using a column master key store provider, which is a client-side software component that encapsulates a key store containing the column master key. Providers for common types of key stores are available in client-side driver libraries from Microsoft, or as standalone downloads. You can also implement your own provider. Always Encrypted capabilities, including built-in column master key store providers vary by a driver library and its version.
See Develop applications using Always Encrypted for the list of client drivers supporting Always Encrypted and for information on how to develop applications that query encrypted columns.
You can also query encrypted columns using SQL tools, for example Query columns using Always Encrypted with Azure Data Studio or Query columns using Always Encrypted with SQL Server Management Studio.
