通过 Azure 使用客户端字段级自动加密

在此页面上

  • 概述
  • 开始之前
  • 设置 KMS
  • 向 Azure 注册您的应用程序
  • 创建客户主密钥
  • 创建应用程序
  • 在密钥保管库集合上创建唯一索引
  • 创建新的数据加密密钥
  • 配置 MongoClient
  • 插入具有加密字段的文档
  • 检索加密文档
  • 了解详情

本指南介绍如何使用 Azure Key Vault 构建启用客户端字段级加密 (CSFLE) 的应用程序。

在完成本指南中的步骤后,您应该具有:

  • 托管在 Azure Key Vault 实例上的客户主密钥。

  • 一个有效的客户端应用程序,使用客户主密钥插入加密文档。

要完成并运行本指南中的代码,您需要按照安装要求页面所示设置开发环境。

在本指南中,代码示例使用占位符文本。在运行示例之前,请用您自己的值替换这些占位符。

例如:

dek_id := "<Your Base64 DEK ID>"

您可以将引号之间的内容替换为您的 DEK ID。

dek_id := "abc123"

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。

提示

要在 Azure Active Directory 上注册应用程序,请按照 Microsoft 官方文档 注册应用程序到 Microsoft 身份平台 快速入门。

重要

记录凭证

确保记录以下凭证:

  • 租户 ID

  • 客户 ID

  • 客户端密钥

在本教程的后面部分,您将需要它们来构造 kmsProviders对象。

要创建新的 Azure Key Vault 实例和客户主密钥,请遵循 Microsoft 官方文档 使用 Azure 门户从 Azure Key Vault 设置和检索密钥 快速入门。

注意

客户主密钥的 RSA 密钥大小应为 2048 或 4096 位。

重要

记录凭证

确保记录以下凭证:

  • 密钥名称

  • 密钥标识符(本指南后面称为keyVaultEndpoint

  • keyVersion

在本教程的后面内容中,您将需要它们来构造dataKeyOpts对象。

授予您的客户端应用程序对该密钥的wrapunwrap权限。

使用以下自动加密设置实例化 MongoDB 客户端对象:

InsertEncryptedDocument.cs
var clientSettings = MongoClientSettings.FromConnectionString(connectionString);
var autoEncryptionOptions = new AutoEncryptionOptions(
keyVaultNamespace: keyVaultNamespace,
kmsProviders: kmsProviders,

var secureClient = new MongoClient(clientSettings);
insert-encrypted-document.go

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)

使用启用了 CSFLE 的MongoClient实例,通过以下代码片段将加密文档插入到medicalRecords.patients命名空间中:

InsertEncryptedDocument.cs
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);
insert-encrypted-document.go
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。

InsertEncryptedDocument.java

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"
}
}
}

为了显示 CSFLE 的功能,以下代码片段使用配置为自动 CSFLE 的客户端以及未配置为自动 CSFLE 的客户端来查询文档。

InsertEncryptedDocument.cs
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($"\n{regularResult}\n");
Console.WriteLine("Finding a document with encrypted client, searching on an encrypted field");
var ssnFilter = Builders<BsonDocument>.Filter.Eq("ssn", 145014000);
var secureResult = secureCollection.Find(ssnFilter).Limit(1).First();
Console.WriteLine($"\n{secureResult}\n");
insert-encrypted-document.go
fmt.Println("Finding a document with regular (non-encrypted) client.")
var resultRegular bson.M
err = regularClient.Database(dbName).Collection(collName).FindOne(context.TODO(), bson.D{{"name", "Jon Doe"}}).Decode(&resultRegular)
if err != nil {
panic(err)
}
outputRegular, err := json.MarshalIndent(resultRegular, "", " ")
if err != nil {
panic(err)
}
fmt.Printf("%s\n", outputRegular)
fmt.Println("Finding a document with encrypted client, searching on an encrypted field")
var resultSecure bson.M

if err != nil {
panic(err)
}
outputSecure, err := json.MarshalIndent(resultSecure, "", " ")
if err != nil {
panic(err)
}
fmt.Printf("%s\n", outputSecure)
InsertEncryptedDocument.java
System.out.println("Finding a document with regular (non-encrypted) client.");
Document docRegular = mongoClientRegular.getDatabase(recordsDb).getCollection(recordsColl).find(eq("name", "Jon Doe")).first();
System.out.println(docRegular.toJson());
System.out.println("Finding a document with encrypted client, searching on an encrypted field");
Document docSecure = mongoClientSecure.getDatabase(recordsDb).getCollection(recordsColl).find(eq("ssn", 241014209)).first();
System.out.println(docSecure.toJson());
insert_encrypted_document.js
console.log("Finding a document with regular (non-encrypted) client.");
console.log(
await regularClient.db(db).collection(coll).findOne({ name: /Jon/ })
);
console.log(
"Finding a document with encrypted client, searching on an encrypted field"
);
console.log(
await secureClient.db(db).collection(coll).findOne({ ssn: "241014209" })

insert_encrypted_document.py
print("Finding a document with regular (non-encrypted) client.")
result = regularClient.medicalRecords.patients.find_one({"name": "Jon Doe"})
pprint.pprint(result)
print("Finding a document with encrypted client, searching on an encrypted field")
pprint.pprint(secureClient.medicalRecords.patients.find_one({"ssn": 241014209}))

上述代码片段的输出应如下所示:
