Usar criptografia no nível do campo automática no lado do cliente com KMIP

Configure seu provedor de chaves compatível com KMIP

Para conectar um cliente de driver MongoDB ao seu fornecedor de chaves compatível com KMIP , você deve configurar seu provedor de chaves compatível com KMIPpara que ele aceite o certificado TLS do seu cliente.

Consulte a documentação do seu provedor de chaves compatível com KMIPpara obter informações sobre como aceitar seu certificado de cliente.

Especifique seus certificados

Seu cliente deve se conectar ao seu provedor de chaves compatível com KMIPpor meio de TLS e apresentar um certificado de cliente que seu provedor de chaves compatível com KMIPaceite:

var tlsOptions = new Dictionary<string, SslSettings>();
var sslSettings = new SslSettings();
var clientCertificate = new X509Certificate2("<path to your pkcs12 client certificate file>");
sslSettings.ClientCertificates = new List<X509Certificate>() {
    clientCertificate,
 };
tlsOptions.Add(provider, sslSettings);

openssl pkcs12 -export -out "<new pkcs12 certificate>" -in "<certificate to convert>" \
-name "<new certificate name>" -password "<new certificate password>"

tlsConfig := make(map[string]*tls.Config)
tlsOpts := map[string]interface{}{
	"tlsCertificateKeyFile": "<path to your client certificate file>",
	"tlsCAFile":             "<path to file containing your Certificate Authority certificate>",
}
kmipConfig, err := options.BuildTLSConfig(tlsOpts)
tlsConfig["kmip"] = kmipConfig

-Djavax.net.ssl.keyStoreType=pkcs12
-Djavax.net.ssl.keyStore=<path to pkcs12 KeyStore containing your client certificate>
-Djavax.net.ssl.keyStorePassword=<KeyStore password>

const tlsOptions = {
  kmip: {
    tlsCAFile:
      "<path to file containing your Certificate Authority certificate>",
    tlsCertificateKeyFile: "<path to your client certificate file>",
  },
};

tls_options = {
    "kmip": {
        "tlsCAFile": "<path to file containing your Certificate Authority certificate>",
        "tlsCertificateKeyFile": "<path to your client certificate file>",
    }
}

Crie um índice único em sua coleção de cofre de chaves

Crie um índice único no campo keyAltNames no seu espaço de nomes encryption.__keyVault.

   });
   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),
       kms_tls_options=tls_options,
   )
   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)

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 seu endpoint KMIP

   Especifique kmip no seu objeto kmsProviders e insira o endpoint URI do seu provedor de chaves compatível com KMIP :

   C#

   Go

   Java (Sync)

   Node.js

   Python

   var kmsProviders = new Dictionary<string, IReadOnlyDictionary<string, object>>();
   var provider = "kmip";
   var kmipKmsOptions = new Dictionary<string, object>
   {
      { "endpoint", "<endpoint for your KMIP-compliant key provider>" },
   };
   kmsProviders.Add(provider, kmipKmsOptions);

   provider := "kmip"
   kmsProviders := map[string]map[string]interface{}{
   	provider: {
   		"endpoint": "<endpoint for your KMIP-compliant key provider>",
   	},
   }

   String kmsProvider = "kmip";
   Map<String, Map<String, Object>> kmsProviders = new HashMap<String, Map<String, Object>>();
   Map<String, Object> providerDetails = new HashMap<>();
   providerDetails.put("endpoint", "<endpoint for your KMIP-compliant key provider>");
   kmsProviders.put(kmsProvider, providerDetails);

   const provider = "kmip";
   const kmsProviders = {
     kmip: {
       endpoint: "<endpoint for your KMIP-compliant key provider>",
     },
   };

   provider = "kmip"
   kms_providers = {
       provider: {"endpoint": "<endpoint for your KMIP-compliant key provider>"}
   }

3. Crie um esquema de criptografia para sua coleção

   Crie um esquema de criptografia que especifique como o aplicativo cliente criptografa os campos dos documentos:

   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

   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 que usam as variáveis declaradas nas etapas anteriores:

   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,
       tlsOptions: tlsOptions
       );
   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,
       tlsOptions: tlsOptions
       );
   clientSettings.AutoEncryptionOptions = autoEncryptionOptions;
   var secureClient = new MongoClient(clientSettings);

   autoEncryptionOpts := options.AutoEncryption().
   	SetKmsProviders(kmsProviders).
   	SetKeyVaultNamespace(keyVaultNamespace).
   	SetSchemaMap(schemaMap).
   	SetExtraOptions(extraOptions).SetTLSConfig(tlsConfig)
   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,
       tlsOptions,
     },
   });

   fle_opts = AutoEncryptionOpts(
       kms_providers,
       key_vault_namespace,
       schema_map=patient_schema,
       kms_tls_options=tls_options,
       **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.

Console.WriteLine("Finding a document with regular (non-encrypted) client.");
var filter = Builders<BsonDocument>.Filter.Eq("name", "Jon Doe");
var regularResult = regularCollection.Find(filter).Limit(1).ToList()[0];

Console.WriteLine("Finding a document with encrypted client");
var ssnFilter = Builders<BsonDocument>.Filter.Eq("name", "Jon Doe");
var secureResult = secureCollection.Find(ssnFilter).Limit(1).First();
Console.WriteLine($"\n{secureResult}\n");

pprint.pprint(result)
print("Finding a document with encrypted client")
pprint.pprint(secureClient.medicalRecords.patients.find_one({"name": "Jon Doe"}))

A saída do trecho de código anterior deve ser semelhante a esta:
