MongoClient Options for CSFLE

Overview概述

View information about the Client-Side Field Level Encryption (CSFLE)-specific configuration options for MongoClient instances.

AutoEncryptionOpts

Pass an autoEncryptionOpts object to your MongoClient instance to specify CSFLE-specific options.

The following table describes the structure of an autoEncryptionOpts object:

ParameterType类型RequiredDescription描述
keyVaultClientMongoClientNo

A MongoClient instance configured to connect to the MongoDB instance hosting your Key Vault collection.

If you omit the keyVaultClient option, the MongoDB instance specified to your MongoClient instance containing the autoEncryptionOpts configuration is used as the host of your Key Vault collection.

To learn more about Key Vault collections, see Encryption Keys and Key Vaults.

keyVaultNamespaceString字符串YesThe full namespace of the Key Vault collection.
kmsProvidersObjectYes

The Key Management System (KMS) used by Client-Side Field Level Encryption for managing your Customer Master Keys (CMKs).

To learn more about kmsProviders objects, see KMS Providers.

To learn more about Customer Master Keys, see Encryption Keys and Key Vaults.

tlsOptionsObjectNo

An object that maps Key Management System provider names to TLS configuration options.

To learn more about TLS options see: TLS Options.

To learn more about TLS see: TLS/SSL (Transport Encryption).

schemaMapObjectNo

An encryption schema.

To learn how to construct an encryption schema, see Encryption Schemas.

For complete documentation of encryption schemas, see CSFLE Encryption Schemas.

bypassAutoEncryptionBoolean布尔值No

Specify true to bypass automatic Client-Side Field Level Encryption rules and perform explicit encryption. bypassAutoEncryption does not disable automatic decryption.

To learn more about this option, see Automatic Decryption.

Example示例

To view a code-snippet demonstrating how to use autoEncryptionOpts to configure your MongoClient instance, select the tab corresponding to your driver:

MongoDB Shell


var autoEncryptionOpts =
{
   "keyVaultNamespace" : "<database>.<collection>",
   "kmsProviders" : { ... },
   "schemaMap" : { ... }
}

cluster = Mongo(
  "<Your Connection String>",
  autoEncryptionOpts
);

Tip

Environment Variables

If possible, consider defining the credentials provided in kmsProviders as environment variables, and then passing them to mongosh using the --eval option. This minimizes the chances of credentials leaking into logs.

C#
var clientSettings = MongoClientSettings.FromConnectionString(_connectionString);
var autoEncryptionOptions = new AutoEncryptionOptions(
    keyVaultNamespace: keyVaultNamespace,
    kmsProviders: kmsProviders,
    schemaMap: schemaMap,
    extraOptions: extraOptions);
clientSettings.AutoEncryptionOptions = autoEncryptionOptions;
var client = new MongoClient(clientSettings);
Go


autoEncryptionOpts := options.AutoEncryption().
	SetKmsProviders(provider.Credentials()).
	SetKeyVaultNamespace(keyVaultNamespace).
	SetSchemaMap(schemaMap).
	SetExtraOptions(extraOptions)
client, err := mongo.Connect(context.TODO(), options.Client().ApplyURI(uri).SetAutoEncryptionOptions(autoEncryptionOpts))
Java(Sync)
MongoClientSettings clientSettings = MongoClientSettings.builder()
    .applyConnectionString(new ConnectionString("mongodb://localhost:27017"))
    .autoEncryptionSettings(AutoEncryptionSettings.builder()
        .keyVaultNamespace(keyVaultNamespace)
        .kmsProviders(kmsProviders)
        .schemaMap(schemaMap)
        .extraOptions(extraOptions)
        .build())
    .build();

MongoClient mongoClient = MongoClients.create(clientSettings);
Node.js
const secureClient = new MongoClient(connectionString, {
  monitorCommands: true,
  autoEncryption: {
    keyVaultNamespace,
    kmsProviders,
    schemaMap: patientSchema,
    extraOptions: extraOptions,
  },
});
Python
fle_opts = AutoEncryptionOpts(
  kms_providers,
  key_vault_namespace,
  schema_map=patient_schema,
  **extra_options
)
client = MongoClient(connection_string, auto_encryption_opts=fle_opts)
