Managing data encryption
You can encrypt data on the Business Central server by generating new or importing existing encryption keys that you enable on the Business Central server instance that connects to the database.
For more information, see Encrypting Data in Dynamics 365 Business Central in Developer and IT-Pro help.
Note
Note:
You can turn on or turn off encryption only if you are using an on-premises version of Business Central. Encryption is always turned on for online versions, and you cannot turn it off.
