Criar uma chave mestra do cliente

Você deve criar uma chave mestre do cliente (CMK) para executar o CSFLE.

Crie uma chave mestra do cliente de 96 bytes e salve-a no seu provedor de chaves locais, que é o seu sistema de arquivos, como o arquivo 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)

Crie um índice único em sua coleção do Key Vault

Crie um índice único parcial no campo keyAltNames no seu namespace encryption.__keyVault . Esse índice precisa ter uma partialFilterExpression para documentos onde existem keyAltNames .

A criptografia do nível do campo no lado do cliente depende da singularidade imposta pelo servidor dos principais nomes alternativos.

Selecione a guia correspondente ao driver MongoDB de sua preferência:

var connectionString = "<Your MongoDB URI>";
var keyVaultNamespace = CollectionNamespace.FromFullName("encryption.__keyVault");
var keyVaultClient = new MongoClient(connectionString);
var indexOptions = new CreateIndexOptions<BsonDocument>();
indexOptions.Unique = 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

Criar uma chave de criptografia de dados

1. Leia a chave mestre do cliente e especifique as configurações do provedor KMS

   Recupere o conteúdo do arquivo de chave mestra do cliente que você gerou na etapa Criar uma chave mestra do cliente deste guia.

   Use o valor CMK nas configurações do provedor KMS. O cliente usa essas configurações para descobrir a CMK. Como você está usando o provedor de chave local, defina o nome do provedor como local.

   C#

   Go

   Java (Sync)

   Node.js

   Python

   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
       },
   }

2. Criar uma chave de criptografia de dados

   Crie um cliente com sua string de conexão do MongoDB e o namespace da collection de cofre de chaves e crie um diretório de dados:

   Observação

   Permissões de namespace da coleção de cofre de chaves

   Para concluir este tutorial, o usuário do banco de dados que seu aplicativo usa para se conectar ao MongoDB deve ter permissões dbAdmin nos seguintes namespaces:

   • encryption.__keyVault

   • medicalRecords database

   C#

   Go

   Java (Sync)

   Node.js

   Python

   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();

   Observação

   Importar ClientEncryption

   Ao usar o driver Node.js v6.0 e posterior, você deve importar ClientEncryption de mongodb.

   Para versões anteriores do driver, importe ClientEncryption de mongodb-client-encryption.

   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)

   A saída do código acima deve ser semelhante ao seguinte:

   DataKeyId [base64]: 3k13WkSZSLy7kwAAP4HDyQ==

Configure o MongoClient

1. Especifique o namespace da coleção do Key Vault

   Especifique encryption.__keyVault como o namespace da coleção Key Vault.

   C#

   Go

   Java (Sync)

   Node.js

   Python

   var keyVaultNamespace = CollectionNamespace.FromFullName("encryption.__keyVault");

   keyVaultNamespace := "encryption.__keyVault"

   String keyVaultNamespace = "encryption.__keyVault";

   const keyVaultNamespace = "encryption.__keyVault";

   key_vault_namespace = "encryption.__keyVault"

2. Especifique a chave mestre do cliente local

   Especifique o provedor de KMS e especifique sua chave em linha:

   C#

   Go

   Java (Sync)

   Node.js

   Python

   var kmsProviders = new Dictionary<string, IReadOnlyDictionary<string, object>>();
   var provider = "local";
   var localMasterKeyPath = "master-key.txt";
   string localMasterKeyBase64Read = File.ReadAllText(localMasterKeyPath);
   var localMasterKeyBytes = Convert.FromBase64String(localMasterKeyBase64Read);
   var localOptions = new Dictionary<string, object>
   {
       { "key", localMasterKeyBytes }
   };
   kmsProviders.Add(provider, localOptions);

   key, err := ioutil.ReadFile("master-key.txt")
   if err != nil {
   	log.Fatalf("Could not read the key from master-key.txt: %v", err)
   }
   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 fs = require("fs");
   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
       },
   }

3. Crie um esquema de criptografia para sua coleção

   Dica

   Adicione sua chave de encriptação de dados ID Base64

   Certifique-se de atualizar o seguinte código para incluir seu ID Base64 DEK . Você recebeu esse valor na etapa Gerar sua chave de criptografia de dados deste guia.

   C#

   Go

   Java (Sync)

   Node.js

   Python

   var keyId = "<Your base64 DEK ID here>";
   var schema = new BsonDocument
   {
      { "bsonType", "object" },
      {
          "encryptMetadata",
          new BsonDocument("keyId", new BsonArray(new[] { new BsonBinaryData(Convert.FromBase64String(keyId), BsonBinarySubType.UuidStandard) }))
      },
      {
          "properties",
          new BsonDocument

4. Especifique o local da biblioteca compartilhada de criptografia automática

   C#

   Go

   Java (Sync)

   Node.js

   Python

   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>"
   }

   Observação

   Opções de criptografia automática

   As opções de criptografia automática fornecem informações de configuração para a Biblioteca compartilhada de criptografia automática, que modifica o comportamento do aplicativo ao acessar campos criptografados.

   Para saber mais sobre a Biblioteca compartilhada de criptografia automática, consulte a página Instalar e configurar uma biblioteca CSFLE .

5. Criar o MongoClient

   Instale instantaneamente um objeto de cliente MongoDB com as seguintes configurações de criptografia automática:

   C#

   Go

   Java (Sync)

   Node.js

   Python

   C# Driver v3.0+

   Driver C# < v3.0

   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)

Inserir um documento com campos criptografados

Use sua instância de MongoClient habilitada para CSFLE para inserir um documento com campos criptografados no namespace medicalRecords.patients usando o seguinte trecho de código:

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)
}

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",
)

Quando você insere um documento, o cliente habilitado para CSFLE criptografa os campos do documento de forma que ele se pareça com o seguinte:

{
  "_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"
    }
  }
}

Recupere seu documento com campos criptografados

Recupere o documento com campos criptografados inseridos na etapa Inserir um documento com campos criptografados deste guia.

Para mostrar a funcionalidade do CSFLE, as seguintes consultas de trecho de código para seu documento com um cliente configurado para CSFLE automático, bem como um cliente que não está configurado para CSFLE automático.
