Always Encrypted on Sql 2017 Express Edition I am so tentative to decide to use Always Encrypted tool, however I have a question → I'm working on a project with SQL Server 2017 - 14 Express Edition. 

And I'm pretty sure they aren't going to buy the Enterprise Edition.

Even so, Can I use this tool? Or is there any limitation related to the final version of SQL? I didn't find any limitation at the official documentation from Microsoft

Thanks a lot.
As per this link, Always Encrypted is supported in SQL Server 2017 Express Edition.
