  By

A few weeks ago, I wrote Part 1, 2 and 3 of this series, which was a beginner’s guide to Always Encrypted. In part 4, I am going to talk about the changes that are coming in vNext of SQL Server.

In the current available versions of SQL Server 2016 and 2017, along with Azure SQL Database, the cost of using AE was way too high for many companies.

Verify Your Setup First, let’s verify that the table is still encrypted, and nothing changed after you ran through the Part 1 examples. To confirm, simply query sys.columns, script out the table, or query the data to check that… Continue Reading

Encryption has always been intriguing to me but seemed like it could be a very complex process to set up. However, SQL Server has made it very simple when they introduced Always Encrypted (AE) into SQL Server 2016 and Azure SQL Database.

Additionally, Always Encrypted is available in Standard (and Express) Edition, starting with SQL Server 2016 SP1.  You can easily encrypt a social security number (SSN) which is considered very sensitive within the United… Continue Reading
