MongoClient Options for Queryable Encryption

Overview

View information about the Queryable Encryption specific configuration options for MongoClient instances.

AutoEncryptionOpts

Pass an AutoEncryptionOpts object to your MongoClient instance to specify Queryable Encryption specific options.

The following table describes the structure of an AutoEncryptionOpts object:

Parameter
Type
Required
Description
keyVaultClient
MongoClient
No

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 Key Vault Collections.

keyVaultNamespace
String
Yes
The full namespace of the Key Vault collection.
kmsProviders
Object
Yes

The Key Management System (KMS) used by Queryable 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 Keys and Key Vaults.

encryptedFieldsMap
Object
No

An encryption schema.

To learn how to construct an encryption schema, see Field Encryption and Queryability.

bypassQueryAnalysis
Boolean
No
Disables automatic analysis of outgoing commands. Set bypassQueryAnalysis to true to use explicit encryption on indexed fields without the crypt_shared library. Defaults to false if not specified.

Example

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

var AutoEncryptionOpts =
{
   "keyVaultClient" : keyVaultClient,
   "keyVaultNamespace" : "<database>.<collection>",
   "kmsProviders" : { ... },
   "bypassQueryAnalysis": "<boolean value>", // optional - defaults to false
   "encryptedFieldsMap" : { ... }
}
cluster = Mongo(
  "mongodb://myhostexample.net:27017/?replicaSet=myReplicaSet",
  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.

const secureClient = new MongoClient(connectionString, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
  monitorCommands: true,
  autoEncryption: {
    keyVaultNamespace,
    kmsProviders,
    bypassQueryAnalysis, // optional - defaults to false
    encryptedFieldsMap: patientSchema,
    extraOptions: extraOptions,
  },
});

To learn about additional options for configuring Automatic Encryption Shared Library, see Configuration.
