You can access the articles through the following links: For information about enabling Always Encrypted in client applications and their drivers, refer to the MSDN article Always Encrypted (client development), which points you to details about several drivers, including .NET Framework Data Provider for SQL Server, Microsoft JDBC Driver for SQL Server, and ODBC Driver for SQL Server.To create these objects, I used the following T-SQL script: You do not need to create this database and table to try out the examples. Just substitute the target database and table as appropriate when going through the examples.That said, you do need to be working in SQL Server Management Studio (SSMS) to follow along.When SQL Server 2016 was first released, the Always Encrypted feature was available only to the Enterprise and Developer editions, but with the release of SQL Server 2016 Service Pack 1, Always Encrypted is now available to all editions.There’s not much you need to do to prepare a database for enabling Always Encrypted, other than to be running an instance of SQL Server 2016, with SP1 installed if necessary.The database engine stores the column encryption key on the SQL Server instance where Always Encrypted is implemented.
The article focuses primarily on the SQL Server side of the equation, demonstrating how to create the two encryption keys and encrypt the columns.
However, before you try to implement Always Encrypted, you should be aware of the many limitations that come with this feature.
To begin with, you cannot use Always Encrypted to protect columns configured with the following data types: Always Encrypted also comes with a number of other restrictions.
For testing purposes, however, we can use a single machine, as I’ve done for these examples.
The simplest way to implement Always Encrypted is to run the SSMS Always Encrypted wizard, which steps you through the process of applying encryption to one or more existing columns within a database’s tables.
