Connect to Server (Always Encrypted page) - Database Engine

  • आलेख

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

Use this tab to view or specify Always Encrypted column encryption options when you connect to Azure SQL Database, Azure SQL Managed Instance, or SQL Server. Use this tab to view or specify Always Encrypted secure enclave options when you connect to Azure SQL Database or SQL Server. Access this tab by selecting Options >> on the Login tab.

Always Encrypted tab

The Always Encrypted tab has two checkboxes.

Enable Always Encrypted (column encryption)

By default, Always Encrypted is disabled for a database connection. Enabling Always Encrypted for a database connection instructs the .NET Framework Data Provider for SQL Server, used by SQL Server Management Studio (SSMS), to attempt to transparently:

  • Decrypt any values that are retrieved from encrypted columns and returned in query results.
  • Encrypt the values of the parameterized Transact-SQL variables that target encrypted database columns.

SSMS uses the .NET Framework Data Provider for SQL Server. If you don't enable Always Encrypted for a connection, the .NET Framework Data Provider doesn't try to encrypt query parameters or decrypt results. For more information, see Query columns using Always Encrypted with SQL Server Management Studio.

Enable secure enclaves

Enable this option when you connect to a database configured to use Always Encrypted with secure enclaves. For more information, see Getting started using Always Encrypted with secure enclaves.

Enclave attestation

The Enclave attestation section has two options.

Protocol

Select the attestation protocol to use when you connect to a database configured to use Always Encrypted with secure enclaves. The protocol value determines:

  • If the client app uses attestation, and, if so,
  • It specifies the type of the attestation service it uses.

Available options are None, Host Guardian Service, and Microsoft Azure Attestation. For more information, see Always Encrypted with secure enclaves.

URL

Enter the configured URL for the selected attestation protocol. The URL is specific to the type of enclave and SQL in use.

Attestation isn't supported for Azure SQL Database with VBS enclaves. The URL option is disabled if None is selected for Protocol.
