Raul Gonzalez wants to combine Always Encrypted with temporal tables in SQL Server 2016:
Again the wall. There is no way you can choose a temporal table and apply encryption to a column or columns using the wizard.
I tried then using the powershell (after manually creating the keys) as this is true the only way to encrypt existing columns, just in case.
Raul doesn’t stop there, though, and he does figure out a workaround.
