 > The driver contains a list of AKV endpoints which it trusts. Starting with driver version 17.5.2, this list is configurable: set the `AKVTrustedEndpoints` property in the driver or DSN's ODBCINST.INI or ODBC.INI registry key (Windows) or `odbcinst.ini` or `odbc.ini` file section (Linux/macOS) to a semicolon-delimited list. Setting it in the DSN takes precedence over a setting in the driver. If the value begins with a semicolon, it extends the default list; otherwise, it replaces the default list. The default list (as of 17.5) is `vault.azure.net;vault.azure.cn;vault.usgovcloudapi.net;vault.microsoftazure.de`. Starting with 17.7, the list also includes `managedhsm.azure.net;managedhsm.azure.cn;managedhsm.usgovcloudapi.net;managedhsm.microsoftazure.de`.

 ### Using the Windows Certificate Store provider
 
 The ODBC Driver for SQL Server on Windows includes a built-in column master key store provider for the Windows Certificate Store, named `MSSQL_CERTIFICATE_STORE`. (This provider isn't available on macOS or Linux.) With this provider, the CMK is stored locally on the client machine and no extra configuration by the application is necessary to use it with the driver. However, the application must have access to the certificate and its private key in the store. For more information, see [Create and Store Column Master Keys (Always Encrypted)](../../relational-databases/security/encryption/create-and-store-column-master-keys-always-encrypted.md).
