快速入门
Overview
本指南向您展示如何使用自动客户端字段级加密 (CSFLE) 和 MongoDB 驱动程序来加密文档。
完成本指南后,您应该具备以下知识和软件:
了解配置驱动程序以加密文档字段的步骤。
一个有效但不适合生产的客户端应用程序,它利用自动客户端字段级加密。
重要
请勿在生产中使用此应用程序
由于此示例应用程序在应用程序的文件系统上存储了加密密钥,因此您可能会遇到未经授权访问该密钥或丢失解密数据的密钥的风险。
要查看演示如何创建支持 CSFLE 的生产就绪应用程序的教程,请参阅教程。
开始之前
要完成并运行本指南中的代码,您需要按照安装要求页面中的步骤来设置开发环境。
从页面右侧的 Select your language(选择语言)下拉菜单中,选择要查看代码示例的编程语言。

重要
使用 go build
或 go run
构建或运行本指南中的Go代码时,请始终包含 cse
构建约束以启用CSFLE 。 有关包含构建约束的示例,请参阅以下shell命令:
go run -tags cse insert-encrypted-document.go
// You are viewing the Java synchronous driver code examples. // Use the dropdown menu to select a different driver.
// You are viewing the Node.js driver code examples. // Use the dropdown menu to select a different driver.
# You are viewing the Python driver code examples. # Use the dropdown menu to select a different driver.
创建客户主密钥
您必须创建客户主密钥 ( CMK ) 才能执行 CSFLE。
创建 96 字节的客户主密钥并将其保存在本地密钥提供商(即您的文件系统)中,作为文件master-key.txt
:
const fs = require("fs"); const crypto = require("crypto"); try { fs.writeFileSync("master-key.txt", crypto.randomBytes(96)); } catch (err) { console.error(err); }
using (var randomNumberGenerator = System.Security.Cryptography.RandomNumberGenerator.Create()) { var bytes = new byte[96]; randomNumberGenerator.GetBytes(bytes); var localMasterKeyBase64Write = Convert.ToBase64String(bytes); Console.WriteLine(localMasterKeyBase64Write); File.WriteAllText("master-key.txt", localMasterKeyBase64Write); }
func localMasterKey() []byte { key := make([]byte, 96) if _, err := rand.Read(key); err != nil { log.Fatalf("Unable to create a random 96 byte data key: %v", err) } if err := ioutil.WriteFile("master-key.txt", key, 0644); err != nil { log.Fatalf("Unable to write key to file: %v", err) } return key }
byte[] localMasterKeyWrite = new byte[96]; new SecureRandom().nextBytes(localMasterKeyWrite); try (FileOutputStream stream = new FileOutputStream("master-key.txt")) { stream.write(localMasterKeyWrite); }
import os path = "master-key.txt" file_bytes = os.urandom(96) with open(path, "wb") as f: f.write(file_bytes)
警告
保护生产环境中的本地密钥文件
提示
从命令行生成 CMK
使用以下命令从 Unix Shell 或 PowerShell 生成 CMK :
Unix shell:
echo $(head -c 96 /dev/urandom | base64 | tr -d '\n') PowerShell:
$r=[byte[]]::new(64);$g=[System.Security.Cryptography.RandomNumberGenerator]::Create();$g.GetBytes($r);[Convert]::ToBase64String($r)
将上述命令的输出保存到名为 customer-master-key.txt
的文件中。

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
字段上创建部分唯一索引。 对于存在keyAltNames
的文档,此索引应具有partialFilterExpression
。
客户端字段级加密取决于服务器强制执行的密钥备用名称的唯一性。
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);

创建数据加密密钥
读取客户主密钥并指定 KMS 提供商设置
检索您在本指南的创建客户主密钥步骤中生成的客户主密钥文件的内容。
使用KMS提供商设置中的集合扫描值。客户端使用这些设置来发现集合扫描 。当您使用本地密钥提供程序时,请将提供商名称设立为
local
。var kmsProviders = new Dictionary<string, IReadOnlyDictionary<string, object>>(); var provider = "local"; string localMasterKeyBase64Read = File.ReadAllText("master-key.txt"); var localMasterKeyBytes = Convert.FromBase64String(localMasterKeyBase64Read); var localOptions = new Dictionary<string, object> { { "key", localMasterKeyBytes } }; kmsProviders.Add("local", localOptions); key, err := ioutil.ReadFile("master-key.txt") if err != nil { log.Fatalf("Could not read the key from master-key.txt: %v", err) } provider := "local" kmsProviders := map[string]map[string]interface{}{"local": {"key": key}} String kmsProvider = "local"; String path = "master-key.txt"; byte[] localMasterKeyRead = new byte[96]; try (FileInputStream fis = new FileInputStream(path)) { if (fis.read(localMasterKeyRead) < 96) throw new Exception("Expected to read 96 bytes from file"); } Map<String, Object> keyMap = new HashMap<String, Object>(); keyMap.put("key", localMasterKeyRead); Map<String, Map<String, Object>> kmsProviders = new HashMap<String, Map<String, Object>>(); kmsProviders.put("local", keyMap); const provider = "local"; const path = "./master-key.txt"; const localMasterKey = fs.readFileSync(path); const kmsProviders = { local: { key: localMasterKey, }, }; path = "./master-key.txt" with open(path, "rb") as f: local_master_key = f.read() kms_providers = { "local": { "key": local_master_key # local_master_key variable from the previous step }, } 创建数据加密密钥
使用 MongoDB 连接字符串和密钥保管库集合命名空间构建客户端,并创建数据加密密钥:
注意
密钥保管库集合命名空间权限
要完成本教程,您的应用程序用于连接到 MongoDB 的数据库用户必须具有对以下命名空间的
dbAdmin
权限:encryption.__keyVault
medicalRecords
database
var clientEncryptionOptions = new ClientEncryptionOptions( keyVaultClient: keyVaultClient, keyVaultNamespace: keyVaultNamespace, kmsProviders: kmsProviders ); var clientEncryption = new ClientEncryption(clientEncryptionOptions); var dataKeyOptions = new DataKeyOptions(); 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() 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()); 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); 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("local") base_64_data_key_id = base64.b64encode(data_key_id) print("DataKeyId [base64]: ", base_64_data_key_id) 上述代码的输出应类似于以下内容:
DataKeyId [base64]: 3k13WkSZSLy7kwAAP4HDyQ==

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>" } 创建 MongoClient
使用以下自动加密设置实例化 MongoDB 客户端对象:
MongoClientSettings.Extensions.AddAutoEncryption(); // .NET/C# Driver v3.0 or later only 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); 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" } } }
