创建应用程序

在密钥保管库集合上创建唯一索引

在 encryption.__keyVault 命名空间中的 keyAltNames 字段上创建唯一索引。

选择与所需的 MongoDB 驱动程序对应的标签页：

var connectionString = "<Your MongoDB URI>";
var keyVaultNamespace = CollectionNamespace.FromFullName("encryption.__keyVault");
var keyVaultClient = new MongoClient(connectionString);
var indexOptions = new CreateIndexOptions<BsonDocument>();
indexOptions.Unique = true;
indexOptions.PartialFilterExpression = new BsonDocument { { "keyAltNames", new BsonDocument { { "$exists", new BsonBoolean(true) } } } };
var builder = Builders<BsonDocument>.IndexKeys;
var indexKeysDocument = builder.Ascending("keyAltNames");
var indexModel = new CreateIndexModel<BsonDocument>(indexKeysDocument, indexOptions);
var keyVaultDatabase = keyVaultClient.GetDatabase(keyVaultNamespace.DatabaseNamespace.ToString());
// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.  
keyVaultDatabase.DropCollection(keyVaultNamespace.CollectionName);
// Drop the database storing your encrypted fields as all
// the DEKs encrypting those fields were deleted in the preceding line.
keyVaultClient.GetDatabase("medicalRecords").DropCollection("patients");
var keyVaultCollection = keyVaultDatabase.GetCollection<BsonDocument>(keyVaultNamespace.CollectionName.ToString());
keyVaultCollection.Indexes.CreateOne(indexModel);

uri := "<Your MongoDB URI>"
keyVaultClient, err := mongo.Connect(context.TODO(), options.Client().ApplyURI(uri))
if err != nil {
	return fmt.Errorf("Connect error for regular client: %v", err)
}
defer func() {
	_ = keyVaultClient.Disconnect(context.TODO())
}()
keyVaultColl := "__keyVault"
keyVaultDb := "encryption"
keyVaultNamespace := keyVaultDb + "." + keyVaultColl
keyVaultIndex := mongo.IndexModel{
	Keys: bson.D{{"keyAltNames", 1}},
	Options: options.Index().
		SetUnique(true).
		SetPartialFilterExpression(bson.D{
			{"keyAltNames", bson.D{
				{"$exists", true},
			}},
		}),
}
// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.
if err = keyVaultClient.Database(keyVaultDb).Collection(keyVaultColl).Drop(context.TODO()); err != nil {
	log.Fatalf("Collection.Drop error: %v", err)
}
// Drop the database storing your encrypted fields as all
// the DEKs encrypting those fields were deleted in the preceding line.
if err = keyVaultClient.Database("medicalRecords").Collection("patients").Drop(context.TODO()); err != nil {
	log.Fatalf("Collection.Drop error: %v", err)
}
_, err = keyVaultClient.Database(keyVaultDb).Collection(keyVaultColl).Indexes().CreateOne(context.TODO(), keyVaultIndex)
if err != nil {
	panic(err)
}

String connectionString = "<Your MongoDB URI>";
String keyVaultDb = "encryption";
String keyVaultColl = "__keyVault";
String keyVaultNamespace = keyVaultDb + "." + keyVaultColl;
MongoClient keyVaultClient = MongoClients.create(connectionString);
// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.
keyVaultClient.getDatabase(keyVaultDb).getCollection(keyVaultColl).drop();
// Drop the database storing your encrypted fields as all
// the DEKs encrypting those fields were deleted in the preceding line.
keyVaultClient.getDatabase("medicalRecords").getCollection("patients").drop();
MongoCollection keyVaultCollection = keyVaultClient.getDatabase(keyVaultDb).getCollection(keyVaultColl);
IndexOptions indexOpts = new IndexOptions().partialFilterExpression(new BsonDocument("keyAltNames", new BsonDocument("$exists", new BsonBoolean(true) ))).unique(true);
keyVaultCollection.createIndex(new BsonDocument("keyAltNames", new BsonInt32(1)), indexOpts);
keyVaultClient.close();

const uri = "<Your Connection String>";
const keyVaultDatabase = "encryption";
const keyVaultCollection = "__keyVault";
const keyVaultNamespace = `${keyVaultDatabase}.${keyVaultCollection}`;
const keyVaultClient = new MongoClient(uri);
await keyVaultClient.connect();
const keyVaultDB = keyVaultClient.db(keyVaultDatabase);
// Drop the Key Vault Collection in case you created this collection
// in a previous run of this application.
await keyVaultDB.dropDatabase();
// Drop the database storing your encrypted fields as all
// the DEKs encrypting those fields were deleted in the preceding line.
await keyVaultClient.db("medicalRecords").dropDatabase();
const keyVaultColl = keyVaultDB.collection(keyVaultCollection);
await keyVaultColl.createIndex(
  { keyAltNames: 1 },
  {
    unique: true,
    partialFilterExpression: { keyAltNames: { $exists: true } },
  }
);

connection_string = "<your connection string here>"
key_vault_coll = "__keyVault"
key_vault_db = "encryption"
key_vault_namespace = f"{key_vault_db}.{key_vault_coll}"
key_vault_client = MongoClient(connection_string)
# Drop the Key Vault Collection in case you created this collection
# in a previous run of this application.
key_vault_client.drop_database(key_vault_db)
# Drop the database storing your encrypted fields as all
# the DEKs encrypting those fields were deleted in the preceding line.
key_vault_client["medicalRecords"].drop_collection("patients")
key_vault_client[key_vault_db][key_vault_coll].create_index(
    [("keyAltNames", ASCENDING)],
    unique=True,
    partialFilterExpression={"keyAltNames": {"$exists": True}},
)

创建新的数据加密密钥

添加 Azure Key Vault 档案

将服务账户凭证添加到启用 CSFLE 的客户端代码中。

var kmsProviders = new Dictionary<string, IReadOnlyDictionary<string, object>>();
var provider = "azure";
var azureKmsOptions = new Dictionary<string, object>
{
   { "tenantId", "<Your Azure Tenant ID>" },
   { "clientId", "<Your Azure Client ID>" },
   { "clientSecret", "<Your Azure Client Secret>" },
};

provider := "azure"
kmsProviders := map[string]map[string]interface{}{
	provider: {
		"tenantId":     "<Your Azure Tenant ID>",
		"clientId":     "<Your Azure Client ID>",
		"clientSecret": "<Your Azure Client Secret>",
	},
}

String kmsProvider = "azure";
Map<String, Map<String, Object>> kmsProviders = new HashMap<String, Map<String, Object>>();
Map<String, Object> providerDetails = new HashMap<>();
providerDetails.put("tenantId", "<Azure account organization>");
providerDetails.put("clientId", "<Azure client ID>");
providerDetails.put("clientSecret", "<Azure client secret>");
kmsProviders.put(kmsProvider, providerDetails);

提示

Azure虚拟机托管身份

如果客户端在Azure虚拟机 (VM) 上运行，则可以允许 VM 使用其托管标识对密钥保管库进行身份验证。

要允许Azure VM 自动提供您的凭证，请分配一个空映射，而不是包含您的Azure的映射，如以下代码所示：

String kmsProvider = "azure";
Map<String, Map<String, Object>> kmsProviders = new HashMap<String, Map<String, Object>>();
Map<String, Object> providerDetails = new HashMap<>();
kmsProviders.put(kmsProvider, providerDetails);

const provider = "azure";
const kmsProviders = {
  azure: {
    tenantId: "<Your Tenant ID>",
    clientId: "<Your Client ID>",
    clientSecret: "<Your Client Secret>",
  },
};

provider = "azure"
kms_providers = {
    provider: {
        "tenantId": "<Azure account organization>",
        "clientId": "<Azure client ID>",
        "clientSecret": "<Azure client secret>",
    }
}

添加您的密钥信息

更新以下代码以指定客户主密钥：

提示

您在本指南的创建客户主密钥步骤中记录了客户主密钥的 ARN 和地区。

kmsProviders.Add(provider, azureKmsOptions);
var dataKeyOptions = new DataKeyOptions(
masterKey: new BsonDocument
{
   { "keyName", "<Your Azure Key Name>" },
   { "keyVaultEndpoint", "<Your Azure Key Vault Endpoint>" },
});

masterKey := map[string]interface{}{
	"keyVaultEndpoint": "<Your Azure Key Vault Endpoint>",
	"keyName":          "<Your Azure Key Name>",
}

BsonDocument masterKeyProperties = new BsonDocument();
masterKeyProperties.put("provider", new BsonString(kmsProvider));
masterKeyProperties.put("keyName", new BsonString("<Azure key name>"));
masterKeyProperties.put("keyVaultEndpoint", new BsonString("<Azure key vault endpoint"));

const masterKey = {
  keyVaultEndpoint: "<Your Key Vault Endpoint>",
  keyName: "<Your Key Name>",
};

master_key = {
    "keyName": "<Azure key name>",
    "keyVersion": "<Azure key version>",
    "keyVaultEndpoint": "<Azure key vault endpoint/key identifier>",
}

生成数据加密密钥

使用本教程的步骤 1 中声明的变量，生成数据加密密钥。

var clientEncryptionOptions = new ClientEncryptionOptions(
    keyVaultClient: keyVaultClient,
    keyVaultNamespace: keyVaultNamespace,
    kmsProviders: kmsProviders
    );
var clientEncryption = new ClientEncryption(clientEncryptionOptions);
var dataKeyId = clientEncryption.CreateDataKey(provider, dataKeyOptions, CancellationToken.None);
var dataKeyIdBase64 = Convert.ToBase64String(GuidConverter.ToBytes(dataKeyId, GuidRepresentation.Standard));
Console.WriteLine($"DataKeyId [base64]: {dataKeyIdBase64}");

clientEncryptionOpts := options.ClientEncryption().SetKeyVaultNamespace(keyVaultNamespace).
	SetKmsProviders(kmsProviders)
clientEnc, err := mongo.NewClientEncryption(keyVaultClient, clientEncryptionOpts)
if err != nil {
	return fmt.Errorf("NewClientEncryption error %v", err)
}
defer func() {
	_ = clientEnc.Close(context.TODO())
}()
dataKeyOpts := options.DataKey().
	SetMasterKey(masterKey)
dataKeyID, err := clientEnc.CreateDataKey(context.TODO(), provider, dataKeyOpts)
if err != nil {
	return fmt.Errorf("create data key error %v", err)
}
fmt.Printf("DataKeyId [base64]: %s\n", base64.StdEncoding.EncodeToString(dataKeyID.Data))

ClientEncryptionSettings clientEncryptionSettings = ClientEncryptionSettings.builder()
        .keyVaultMongoClientSettings(MongoClientSettings.builder()
                .applyConnectionString(new ConnectionString(connectionString))
                .build())
        .keyVaultNamespace(keyVaultNamespace)
        .kmsProviders(kmsProviders)
        .build();
MongoClient regularClient = MongoClients.create(connectionString);
ClientEncryption clientEncryption = ClientEncryptions.create(clientEncryptionSettings);
BsonBinary dataKeyId = clientEncryption.createDataKey(kmsProvider, new DataKeyOptions().masterKey(masterKeyProperties));
String base64DataKeyId = Base64.getEncoder().encodeToString(dataKeyId.getData());
System.out.println("DataKeyId [base64]: " + base64DataKeyId);
clientEncryption.close();

const client = new MongoClient(uri);
await client.connect();
const encryption = new ClientEncryption(client, {
  keyVaultNamespace,
  kmsProviders,
});
const key = await encryption.createDataKey(provider, {
  masterKey: masterKey,
});
console.log("DataKeyId [base64]: ", key.toString("base64"));
await keyVaultClient.close();
await client.close();

注意

导入 ClientEncryption

使用 Node.js 驱动程序 v6.0 及更高版本时，必须从 mongodb 导入 ClientEncryption。

对于较早的驱动程序版本，请从 mongodb-client-encryption 导入 ClientEncryption。

key_vault_database = "encryption"
key_vault_collection = "__keyVault"
key_vault_namespace = f"{key_vault_database}.{key_vault_collection}"
client = MongoClient(connection_string)
client_encryption = ClientEncryption(
    kms_providers,  # pass in the kms_providers variable from the previous step
    key_vault_namespace,
    client,
    CodecOptions(uuid_representation=STANDARD),
)
data_key_id = client_encryption.create_data_key(provider, master_key)
base_64_data_key_id = base64.b64encode(data_key_id)
print("DataKeyId [base64]: ", base_64_data_key_id)

指定自动加密共享库位置
var mongoBinariesPath = "<Full path to your Automatic Encryption Shared Library>"; var extraOptions = new Dictionary<string, object>() { { "cryptSharedLibPath", mongoBinariesPath }, };
extraOptions := map[string]interface{}{ "cryptSharedLibPath": "<Full path to your Automatic Encryption Shared Library>", }
Map<String, Object> extraOptions = new HashMap<String, Object>(); extraOptions.put("cryptSharedLibPath", "<Full path to your Automatic Encryption Shared Library>"));
const extraOptions = { cryptSharedLibPath: "<Full path to your Automatic Encryption Shared Library>", };
extra_options = { "cryptSharedLibPath": "<Full path to your Automatic Encryption Shared Library>" }
注意
自动加密选项
自动加密选项向自动加密共享库提供配置信息，这将修改应用程序在访问加密字段时的行为。
要了解有关自动加密共享库的更多信息，请参阅 CSFLE 的自动加密共享库页面。

创建 MongoClient

使用以下自动加密设置实例化 MongoDB 客户端对象，这些设置使用前面步骤中声明的变量：

var clientSettings = MongoClientSettings.FromConnectionString(connectionString);
var autoEncryptionOptions = new AutoEncryptionOptions(
    keyVaultNamespace: keyVaultNamespace,
    kmsProviders: kmsProviders,
    schemaMap: schemaMap,
    extraOptions: extraOptions
    );
clientSettings.AutoEncryptionOptions = autoEncryptionOptions;
var secureClient = new MongoClient(clientSettings);

autoEncryptionOpts := options.AutoEncryption().
	SetKmsProviders(kmsProviders).
	SetKeyVaultNamespace(keyVaultNamespace).
	SetSchemaMap(schemaMap).
	SetExtraOptions(extraOptions)
secureClient, err := mongo.Connect(context.TODO(), options.Client().ApplyURI(uri).SetAutoEncryptionOptions(autoEncryptionOpts))
if err != nil {
	return fmt.Errorf("Connect error for encrypted client: %v", err)
}
defer func() {
	_ = secureClient.Disconnect(context.TODO())
}()

MongoClientSettings clientSettings = MongoClientSettings.builder()
    .applyConnectionString(new ConnectionString(connectionString))
    .autoEncryptionSettings(AutoEncryptionSettings.builder()
        .keyVaultNamespace(keyVaultNamespace)
        .kmsProviders(kmsProviders)
        .schemaMap(schemaMap)
        .extraOptions(extraOptions)
        .build())
    .build();
MongoClient mongoClientSecure = MongoClients.create(clientSettings);

const secureClient = new MongoClient(connectionString, {
  autoEncryption: {
    keyVaultNamespace,
    kmsProviders,
    schemaMap: patientSchema,
    extraOptions: extraOptions,
  },
});

fle_opts = AutoEncryptionOpts(
    kms_providers, key_vault_namespace, schema_map=patient_schema, **extra_options
)
secureClient = MongoClient(connection_string, auto_encryption_opts=fle_opts)

插入具有加密字段的文档

使用启用了 CSFLE 的 MongoClient 实例，通过以下代码片段将具有加密字段的文档插入到 medicalRecords.patients 命名空间中：

var sampleDocFields = new BsonDocument
{
    { "name", "Jon Doe" },
    { "ssn", 145014000 },
    { "bloodType", "AB-" },
    {
        "medicalRecords", new BsonArray
        {
            new BsonDocument("weight", 180),
            new BsonDocument("bloodPressure", "120/80")
        }
    },
    {
        "insurance", new BsonDocument
        {
            { "policyNumber", 123142 },
            { "provider", "MaestCare" }
        }
    }
};
// Construct an auto-encrypting client
var secureCollection = secureClient.GetDatabase(db).GetCollection<BsonDocument>(coll);
// Insert a document into the collection
secureCollection.InsertOne(sampleDocFields);

test_patient := map[string]interface{}{
	"name":      "Jon Doe",
	"ssn":       241014209,
	"bloodType": "AB+",
	"medicalRecords": []map[string]interface{}{{
		"weight":        180,
		"bloodPressure": "120/80",
	}},
	"insurance": map[string]interface{}{
		"provider":     "MaestCare",
		"policyNumber": 123142,
	},
}
if _, err := secureClient.Database(dbName).Collection(collName).InsertOne(context.TODO(), test_patient); err != nil {
	return fmt.Errorf("InsertOne error: %v", err)
}

注意

您可以将带有bson标签的结构体直接传递给驱动程序进行编码，而无需创建原始 BSON 文档。

ArrayList<Document> medicalRecords = new ArrayList<>();
medicalRecords.add(new Document().append("weight", "180"));
medicalRecords.add(new Document().append("bloodPressure", "120/80"));
Document insurance = new Document()
.append("policyNumber", 123142)
.append("provider",  "MaestCare");
Document patient = new Document()
    .append("name", "Jon Doe")
    .append("ssn", 241014209)
    .append("bloodType", "AB+")
    .append("medicalRecords", medicalRecords)
    .append("insurance", insurance);
mongoClientSecure.getDatabase(recordsDb).getCollection(recordsColl).insertOne(patient);

try {
  const writeResult = await secureClient
    .db(db)
    .collection(coll)
    .insertOne({
      name: "Jon Doe",
      ssn: 241014209,
      bloodType: "AB+",
      medicalRecords: [{ weight: 180, bloodPressure: "120/80" }],
      insurance: {
        policyNumber: 123142,
        provider: "MaestCare",
      },
    });
} catch (writeError) {
  console.error("writeError occurred:", writeError);
}

def insert_patient(
    collection, name, ssn, blood_type, medical_records, policy_number, provider
):
    insurance = {"policyNumber": policy_number, "provider": provider}
    doc = {
        "name": name,
        "ssn": ssn,
        "bloodType": blood_type,
        "medicalRecords": medical_records,
        "insurance": insurance,
    }
    collection.insert_one(doc)
medical_record = [{"weight": 180, "bloodPressure": "120/80"}]
insert_patient(
    secureClient.medicalRecords.patients,
    "Jon Doe",
    241014209,
    "AB+",
    medical_record,
    123142,
    "MaestCare",
)

在您插入文档时，启用了 CSFLE 的客户端对文档字段进行加密，以使其类似于以下内容：

{
  "_id": { "$oid": "<_id of your document>" },
  "name": "Jon Doe",
  "ssn": {
    "$binary": "<cipher-text>",
    "$type": "6"
  },
  "bloodType": {
    "$binary": "<cipher-text>",
    "$type": "6"
  },
  "medicalRecords": {
    "$binary": "<cipher-text>",
    "$type": "6"
  },
  "insurance": {
    "provider": "MaestCare",
    "policyNumber": {
      "$binary": "<cipher-text>",
      "$type": "6"
    }
  }
}

console.log("Finding a document with regular (non-encrypted) client.");
console.log(
  await regularClient.db(db).collection(coll).findOne({ name: /Jon/ })

pprint.pprint(result)
print("Finding a document with encrypted client, searching on an encrypted field")
pprint.pprint(secureClient.medicalRecords.patients.find_one({"ssn": 241014209}))
