Column-Level Encryption in SQL Server

  • Article

Beginning with SQL Server 2005, column-level encryption and decryption capabilities were made available within the database, providing a solution for situations where one-off types of data need to be secured beyond your existing authorization, authentication or firewall settings. This article provides an overview and example of securing a column using native SQL Server cryptography functions.

SQL Server Encryption Symmetric vs. Asymmetric Keys

  • Article

I need to encrypt my data within SQL Server and I plan on using the built-in encryption functionality in SQL Server 2005 and 2008. However, I'm looking at symmetric and asymmetric key algorithms and while I see information saying to use symmetric keys, I don't understand why. What's the difference between the two and why is a symmetric key algorithm preferred over the asymmetric key ones?

Question of the Day

Which Table I

I have this code in SQL Server 2022:

CREATE SCHEMA etl;
GO
CREATE TABLE etl.product
(
    ProductID INT,
    ProductName VARCHAR(100)
);
GO
INSERT etl.product
VALUES
(2, 'Bee AI Wearable');
GO
CREATE TABLE dbo.product
(
    ProductID INT,
    ProductName VARCHAR(100)
);
GO
INSERT dbo.product
VALUES
(1, 'Spiral College-ruled Notebook');
GO
CREATE OR ALTER PROCEDURE etl.GettheProduct
AS
BEGIN
    SELECT  ProductName
    FROM product;
END;
GO
When I execute this code as a user whose default schema is dbo and has rights to the tables and proc, what is returned?
