KeyVault.getKeyByAltName()（mongosh方法）

KeyVault.getKeyByAltName(keyAltName)

获取具有指定 keyAltName 的所有数据加密密钥。

返回：	表示匹配数据加密密钥的文档。

兼容性

此命令可用于以下环境中托管的部署：

MongoDB Atlas：用于云中 MongoDB 部署的完全托管服务

MongoDB Enterprise：基于订阅、自我管理的 MongoDB 版本
MongoDB Community：源代码可用、免费使用且可自行管理的 MongoDB 版本

语法

getKeyByAltName() 通过以下语法实现：

keyVault = db.getMongo().getKeyVault()
keyVault.getKeyByAltName("keyAltName")

行为

需要在数据库连接上配置客户端字段级加密

The mongosh client-side field level encryption methods require a database connection with client-side field level encryption enabled. If the current database connection was not initiated with client-side field level encryption enabled, either:

Use the Mongo() constructor from the mongosh to establish a connection with the required client-side field level encryption options. The Mongo() method supports the following Key Management Service (KMS) providers for Customer Master Key (CMK) management:
or
Use the mongosh command line options to establish a connection with the required options. The command line options only support the Amazon Web Services KMS provider for CMK management.

例子

以下示例使用本地托管的 KMS 进行客户端字段级加密配置。

启动 mongosh

启动mongosh客户端。

mongosh --nodb

生成密钥

要为本地托管的密钥配置客户端字段级加密，请生成一个不带换行符的 base64 编码的 96 字节字符串。

const TEST_LOCAL_KEY = require("crypto").randomBytes(96).toString("base64")

创建客户端字段级加密选项

使用生成的本地密钥字符串创建客户端字段级加密选项：

 let autoEncryptionOpts = {
   "keyVaultNamespace" : "encryption.__dataKeys",
   "kmsProviders" : {
     "local" : {
       "key" : BinData(0, TEST_LOCAL_KEY)
     }
   }
 }

创建加密客户端

使用配置了客户端字段级加密选项的Mongo()构造函数来创建数据库连接。将mongodb://myMongo.example.net URI 替换为目标集群的连接字符串 URI 。

encryptedClient = Mongo(
  "mongodb://myMongo.example.net:27017/?replSetName=myMongo",
   autoEncryptionOpts
)

Retrieve the KeyVault object and use the KeyVault.getKeyByAltName() method to retrieve the data encryption key whose keyAltNames array includes the specified key alternate name:

keyVault.getKeyByAltName("data-encryption-key")

getKeyByAltName() 返回以下数据加密密钥：

{
    "_id" : UUID("b4b41b33-5c97-412e-a02b-743498346079"),
    "keyMaterial" : BinData(0,"PXRsLOAYxhzTS/mFQAI8486da7BwZgqA91UI7NKz/T/AjB0uJZxTvhvmQQsKbCJYsWVS/cp5Rqy/FUX2zZwxJOJmI3rosPhzV0OI5y1cuXhAlLWlj03CnTcOSRzE/YIrsCjMB0/NyiZ7MRWUYzLAEQnE30d947XCiiHIb8a0kt2SD0so8vZvSuP2n0Vtz4NYqnzF0CkhZSWFa2e2yA=="),
    "creationDate" : ISODate("2019-08-12T21:21:30.569Z"),
    "updateDate" : ISODate("2019-08-12T21:21:30.569Z"),
    "status" : 0,
    "version" : Long(0),
    "masterKey" : {
        "provider" : "local"
    },
    "keyAltNames" : [
        "data-encryption-key"
    ]
}
