These are the basic database settings in Microsoft SQL Server and SSMS for testing Always Encrypted in conjunction with YubiHSM.
Step 3 To verify the settings, expand the object Database > Database-Name (in our example the database name is Sales3), and select New Query in the top menu again. Re-enter the SQL query in the example below and click Execute.
SELECT * FROM Table_Customers;
When the SSMS settings take effect, the encrypted database columns are decrypted, and the values displayed in clear text as shown in the screenshot below.
