Viewing decrypted data within SQL Server Management Studio (SSMS) is very easy. SSMS uses .NET 4.6 and the modern SQL Server client, so you can pass in the necessary encryption options. SSMS uses the connection string to access the Master Key and return the data in its decrypted format.
First create a new SQL Connection and Click Options to expand the window.
Then go to the Additional Connections Parameters Tab of the login window and simply type column encryption setting = enabled. Then choose Connect.
