Release Notes

Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider

1.0.0-preview1.19295.2 released 22 October 2019

Fixed

  • Fixed missing NuGet package dependency on Microsoft.Data.SqlClient and updated maximum version attribute for other dependencies.

1.0.0-preview1.19292.1 released 18 October 2019

This is the initial public preview release of the new Microsoft.Data.SqlClient.AlwaysEncrypted.AzureKeyVaultProvider namespace. This library contains the implementation of Microsoft.Data.SqlClient.SqlColumnEncryptionKeyStoreProvider for accessing Azure Key Vault, and the provider class is named as SqlColumnEncryptionAzureKeyVaultProvider.

Working with SQLColumnEncryptionAzureKeyVaultProvider

SqlColumnEncryptionAzureKeyVaultProvider is implemented for Microsoft.Data.SqlClient driver and supports .NET Framework 4.6+ and .NET Core 2.1+. This provider name identifier for this library is "AZURE_KEY_VAULT" and it is not registered in driver by default. Client applications must call SqlConnection.RegisterColumnEncryptionKeyStoreProviders() API only once in the lifetime of driver to register this custom provider by implementing a custom Authentication Callback mechanism.

Once the provider is registered, it can used to perform Always Encrypted operations by creating Column Master Key using Azure Key Vault Key Identifier URL.

A sample C# application to demonstrate Always Encrypted with Azure Key Vault can be download from samples directory: AzureKeyVaultProviderExample.cs
