Next Steps

Queryable Encryption with equality queries is generally available (GA) in MongoDB 7.0 and later. The Queryable Encryption Public Preview, released in version 6.0, is no longer supported. Data encrypted using the Public Preview is incompatible with the feature release. For more information, see Compatibility Changes in MongoDB 7.0.

Overview

This guide shows you how to build an application that implements Queryable Encryption to automatically encrypt and decrypt document fields.

After you complete the steps in this guide, you should have a working client application that is ready for inserting documents with fields encrypted with your Customer Master Key.

Add your KMS credentials

Create a variable containing your KMS credentials with the following structure. Use the Access Key ID and Secret Access Key you used in step 2.2 when you created an AWS IAM user.

kmsProviderCredentials = {
  aws: {
    accessKeyId: process.env["AWS_ACCESS_KEY_ID"], // Your AWS access key ID
    secretAccessKey: process.env["AWS_SECRET_ACCESS_KEY"], // Your AWS secret access key
  },
};

var kmsProviderCredentials = new Dictionary<string, IReadOnlyDictionary<string, object>>();
var kmsOptions = new Dictionary<string, object>
{
    { "accessKeyId", _appSettings["Aws:AccessKeyId"] }, // Your AWS access key ID
    { "secretAccessKey", _appSettings["Aws:SecretAccessKey"] } // Your AWS secret access key
};
kmsProviderCredentials.Add("aws", kmsOptions);

kmsProviderCredentials := map[string]map[string]interface{}{
	"aws": {
		"accessKeyId":     os.Getenv("AWS_ACCESS_KEY_ID"),     // AWS access key ID
		"secretAccessKey": os.Getenv("AWS_SECRET_ACCESS_KEY"), // AWS secret access key
	},
}

Map<String, Object> kmsProviderDetails = new HashMap<>();
kmsProviderDetails.put("accessKeyId", getEnv("AWS_ACCESS_KEY_ID")); // Your AWS access key ID
kmsProviderDetails.put("secretAccessKey", getEnv("AWS_SECRET_ACCESS_KEY")); // Your AWS secret access key
Map<String, Map<String, Object>> kmsProviderCredentials = new HashMap<String, Map<String, Object>>();
kmsProviderCredentials.put("aws", kmsProviderDetails);

kmsProviders = {
  aws: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID, // Your AWS access key ID
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY, // Your AWS secret access key
  },
};

kms_provider_credentials = {
    "aws": {
        "accessKeyId": os.environ['AWS_ACCESS_KEY_ID'], # Your AWS access key ID
        "secretAccessKey": os.environ['AWS_SECRET_ACCESS_KEY'] # Your AWS secret access key
    }
}

Important

Reminder: Authenticate with IAM Roles in Production

To use an IAM role instead of an IAM user to authenticate your application, specify an empty object for your credentials in your KMS provider object. This instructs the driver to automatically retrieve the credentials from the environment:

kmsProviders = {
  aws: { }
};

kmsProviderCredentials.Add("aws", new Dictionary<string, object>);

kmsProviderCredentials := map[string]map[string]interface{}{
  "aws": { },
}

kmsProviderCredentials.put("aws", new HashMap<>());

kmsProviders = {
  aws: { }
};

kms_provider_credentials = {
  "aws": { }
}

Add your CMK credentials

Create a variable containing your Customer Master Key credentials with the following structure. Use the ARN and Region you recorded in step 1.3 when you created a CMK.

customerMasterKeyCredentials = {
  key: process.env["AWS_KEY_ARN"], // Your AWS Key ARN
  region: process.env["AWS_KEY_REGION"], // Your AWS Key Region
};

var customerMasterKeyCredentials = new BsonDocument
{
    { "key", _appSettings["Aws:KeyArn"] }, // Your AWS Key ARN
    { "region", _appSettings["Aws:KeyRegion"] } // Your AWS Key Region
};

customerMasterKeyCredentials := map[string]string{
	"key":    os.Getenv("AWS_KEY_ARN"),    // Your AWS Key ARN
	"region": os.Getenv("AWS_KEY_REGION"), // Your AWS Key Region
}

BsonDocument customerMasterKeyCredentials = new BsonDocument();
customerMasterKeyCredentials.put("provider", new BsonString(kmsProviderName));
customerMasterKeyCredentials.put("key", new BsonString(getEnv("AWS_KEY_ARN"))); // Your AWS Key ARN
customerMasterKeyCredentials.put("region", new BsonString(getEnv("AWS_KEY_REGION"))); // Your AWS Key Region

customerMasterKeyCredentials = {
  key: process.env.AWS_KEY_ARN, // Your AWS Key ARN
  region: process.env.AWS_KEY_REGION, // Your AWS Key Region
};

customer_master_key_credentials = {
    "key": os.environ['AWS_KEY_ARN'],  # Your AWS Key ARN
    "region": os.environ['AWS_KEY_REGION'] # Your AWS Key Region
}

Set automatic encryption options

Note

Automatic Encryption Options

The automatic encryption options provide configuration information to the Automatic Encryption Shared Library, which modifies the application's behavior when accessing encrypted fields.

To learn more about the Automatic Encryption Shared Library, see the Automatic Encryption Shared Library page.

Create an autoEncryptionOptions object with the following options:

The namespace of your Key Vault collection
The kmsProviderCredentials object, which contains your AWS KMS credentials

const autoEncryptionOptions = {
  keyVaultNamespace: keyVaultNamespace,
  kmsProviders: kmsProviderCredentials,
};

Create an AutoEncryptionOptions object with the following options:

The namespace of your Key Vault collection
The kmsProviderCredentials object, which contains your AWS KMS credentials
The extraOptions object, which contains the path to your Automatic Encryption Shared Library

var extraOptions = new Dictionary<string, object>
{
    { "cryptSharedLibPath", _appSettings["CryptSharedLibPath"] } // Path to your Automatic Encryption Shared Library
};
var autoEncryptionOptions = new AutoEncryptionOptions(
    keyVaultNamespace,
    kmsProviderCredentials,
    extraOptions: extraOptions);

Create an AutoEncryption object with the following options:

The namespace of your Key Vault collection
The kmsProviderCredentials object, which contains your AWS KMS credentials
The cryptSharedLibraryPath object, which contains the path to your Automatic Encryption Shared Library

cryptSharedLibraryPath := map[string]interface{}{
	"cryptSharedLibPath": os.Getenv("SHARED_LIB_PATH"), // Path to your Automatic Encryption Shared Library
}
autoEncryptionOptions := options.AutoEncryption().
	SetKeyVaultNamespace(keyVaultNamespace).
	SetKmsProviders(kmsProviderCredentials).
	SetExtraOptions(cryptSharedLibraryPath)

Create an AutoEncryptionSettings object with the following options:

The namespace of your Key Vault collection
The kmsProviderCredentials object, which contains your AWS KMS credentials
The extraOptions object, which contains the path to your Automatic Encryption Shared Library

Map<String, Object> extraOptions = new HashMap<String, Object>();
extraOptions.put("cryptSharedLibPath", getEnv("SHARED_LIB_PATH")); // Path to your Automatic Encryption Shared Library
AutoEncryptionSettings autoEncryptionSettings = AutoEncryptionSettings.builder()
        .keyVaultNamespace(keyVaultNamespace)
        .kmsProviders(kmsProviderCredentials)
        .extraOptions(extraOptions)
        .build();

Create an autoEncryptionOptions object with the following options:

The namespace of your Key Vault collection
The kmsProviders object, which contains your AWS KMS credentials
The sharedLibraryPathOptions object, which contains the path to your Automatic Encryption Shared Library

const extraOptions = {
  cryptSharedLibPath: process.env.SHARED_LIB_PATH, // Path to your Automatic Encryption Shared Library
};
const autoEncryptionOptions = {
  keyVaultNamespace,
  kmsProviders,
  extraOptions,
};

Create an AutoEncryptionOpts object with the following options:

The kms_provider_credentials object, which contains your AWS KMS credentials
The namespace of your Key Vault collection
The path to your Automatic Encryption Shared Library

auto_encryption_options = AutoEncryptionOpts(
    kms_provider_credentials,
    key_vault_namespace,
    crypt_shared_lib_path=os.environ['SHARED_LIB_PATH'] # Path to your Automatic Encryption Shared Library>
)

Add your KMS credentials

Create a variable containing your KMS credentials with the following structure. Use the Azure Key Vault credentials you recorded in the when you registered your application with Azure.

kmsProviderCredentials = {
  azure: {
    tenantId: process.env["AZURE_TENANT_ID"], // Your Azure tenant ID
    clientId: process.env["AZURE_CLIENT_ID"], // Your Azure client ID
    clientSecret: process.env["AZURE_CLIENT_SECRET"], // Your Azure client secret
  },
};

var kmsProviderCredentials = new Dictionary<string, IReadOnlyDictionary<string, object>>();
var kmsOptions = new Dictionary<string, object>
{
    { "tenantId", _appSettings["Azure:TenantId"] }, // Your Azure tenant ID
    { "clientId", _appSettings["Azure:ClientId"] }, // Your Azure client ID
    { "clientSecret", _appSettings["Azure:ClientSecret"] } // Your Azure client secret
};

Add your CMK credentials

Create a variable containing your Customer Master Key credentials with the following structure. Use the CMK details you recorded when you created a CMK.

customerMasterKeyCredentials = {
  keyVaultEndpoint: process.env["AZURE_KEY_VAULT_ENDPOINT"], // Your Azure Key Vault Endpoint
  keyName: process.env["AZURE_KEY_NAME"], // Your Azure Key Name
};

var customerMasterKeyCredentials = new BsonDocument
{
    { "keyVaultEndpoint", _appSettings["Azure:KeyVaultEndpoint"] }, // Your Azure Key Vault Endpoint
    { "keyName", _appSettings["Azure:KeyName"] } // Your Azure Key Name
};

customerMasterKeyCredentials := map[string]string{
	"keyVaultEndpoint": os.Getenv("AZURE_KEY_VAULT_ENDPOINT"), // Your Azure Key Vault Endpoint
	"keyName":          os.Getenv("AZURE_KEY_NAME"),           // Your Azure Key Name
}

BsonDocument customerMasterKeyCredentials = new BsonDocument();
customerMasterKeyCredentials.put("provider", new BsonString(kmsProviderName));
customerMasterKeyCredentials.put("keyName", new BsonString(getEnv("AZURE_KEY_NAME"))); // Your Azure Key Vault Endpoint
customerMasterKeyCredentials.put("keyVaultEndpoint", new BsonString(getEnv("AZURE_KEY_VAULT_ENDPOINT"))); // Your Azure Key Name

customerMasterKeyCredentials = {

Create an encryption client

To create a client for encrypting and decrypting data in encrypted collections, instantiate a new MongoClient using your connection URI and automatic encryption options.

const encryptedClient = Mongo(uri, autoEncryptionOptions);

var clientSettings = MongoClientSettings.FromConnectionString(uri);
clientSettings.AutoEncryptionOptions = qeHelpers.GetAutoEncryptionOptions(
    keyVaultNamespace,
    kmsProviderCredentials);
var encryptedClient = new MongoClient(clientSettings);

encryptedClient, err := mongo.Connect(
	context.TODO(),
	options.Client().ApplyURI(uri).SetAutoEncryptionOptions(autoEncryptionOptions),
)
if err != nil {
	panic(fmt.Sprintf("Unable to connect to MongoDB: %v\n", err))
}
defer func() {
	_ = encryptedClient.Disconnect(context.TODO())
}()

MongoClientSettings clientSettings = MongoClientSettings.builder()
        .applyConnectionString(new ConnectionString(uri))
        .autoEncryptionSettings(autoEncryptionSettings)
        .build();
try (MongoClient encryptedClient = MongoClients.create(clientSettings)) {

const encryptedClient = new MongoClient(uri, {
  autoEncryption: autoEncryptionOptions,
});

encrypted_client = MongoClient(
    uri, auto_encryption_opts=auto_encryption_options)

Map<String, Object> kmsProviderDetails = new HashMap<>();
kmsProviderDetails.put("endpoint", getEnv("KMIP_KMS_ENDPOINT")); // Your KMIP KMS endpoint
Map<String, Map<String, Object>> kmsProviderCredentials = new HashMap<String, Map<String, Object>>();
kmsProviderCredentials.put("kmip", kmsProviderDetails);

kmsProviders = {
  kmip: {
    endpoint: process.env.KMIP_KMS_ENDPOINT, // Your KMIP KMS endpoint
  },
};

kms_provider_credentials = {
    "kmip": {
        "endpoint": os.environ['KMIP_KMS_ENDPOINT'] # Your KMIP KMS endpoint
    }
}

Add your CMK credentials

Create an empty object as shown in the following code example. This prompts your KMIP-compliant key provider to generate a new Customer Master Key.

customerMasterKeyCredentials = {};

var customerMasterKeyCredentials = new BsonDocument();

cmkCredentials := map[string]string{}

BsonDocument customerMasterKeyCredentials = new BsonDocument();

customerMasterKeyCredentials = {};

customer_master_key_credentials = {}

Create an encryption client

To create a client for encrypting and decrypting data in encrypted collections, instantiate a new MongoClient using your connection URI and automatic encryption options.

const encryptedClient = Mongo(uri, autoEncryptionOptions);

var clientSettings = MongoClientSettings.FromConnectionString(uri);
clientSettings.AutoEncryptionOptions = qeHelpers.GetAutoEncryptionOptions(
    keyVaultNamespace,
    kmsProviderCredentials);
var encryptedClient = new MongoClient(clientSettings);

encryptedClient, err := mongo.Connect(
	context.TODO(),
	options.Client().ApplyURI(uri).SetAutoEncryptionOptions(autoEncryptionOptions),
)
if err != nil {
	panic(fmt.Sprintf("Unable to connect to MongoDB: %v\n", err))
}
defer func() {
	_ = encryptedClient.Disconnect(context.TODO())
}()

MongoClientSettings clientSettings = MongoClientSettings.builder()
        .applyConnectionString(new ConnectionString(uri))
        .autoEncryptionSettings(autoEncryptionSettings)
        .build();
try (MongoClient encryptedClient = MongoClients.create(clientSettings)) {

const encryptedClient = new MongoClient(uri, {
  autoEncryption: autoEncryptionOptions,
});

encrypted_client = MongoClient(
    uri, auto_encryption_opts=auto_encryption_options)
