KeyVault.getKeys()

On this page本页内容

New in version 4.2.在版本4.2中新增

KeyVault.getKeys()

getKeys() returns all data encryption keys stored in the key vault associated to the database connection.返回存储在与数据库连接关联的密钥库中的所有数据加密密钥。

getKeys() has the following syntax:具有以下语法:

keyVault = db.getMongo().getKeyVault()
keyVault.getKeys()
Returns:返回:Returns all data encryption keys associated to the key vault.返回与密钥库关联的所有数据加密密钥。

Returns nothing if the key vault is empty.如果密钥库为空,则不返回任何内容。

Behavior行为

Requires Configuring Client-Side Field Level Encryption on Database Connection需要在数据库连接上配置客户端字段级加密

The mongo 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:

Example示例

The following example uses a locally managed KMS for the client-side field level encryption configuration.以下示例将本地管理的KMS用于客户端字段级加密配置。

Configuring client-side field level encryption for a locally managed key requires specifying a base64-encoded 96-byte string with no line breaks. 为本地管理的密钥配置客户端字段级加密需要指定不带换行符的base64编码的96字节字符串。The following operation generates a key that meets the stated requirements and loads it into the mongo shell:以下操作生成满足所述要求的密钥并将其加载到mongo shell中:

TEST_LOCAL_KEY=$(echo "$(head -c 96 /dev/urandom | base64 | tr -d '\n')")
mongosh --nodb --shell --eval "var TEST_LOCAL_KEY='$TEST_LOCAL_KEY'"

Create the client-side field level encryption object using the generated local key string:

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

Use the Mongo() constructor to create a database connection with the client-side field level encryption options. Replace the mongodb://myMongo.example.net URI with the connection string URI of the target cluster.

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

Retrieve the KeyVault object and use the KeyVault.getKeys() method to retrieve all data encryption keys in the key vault:

keyVault.getKeys()

getKeys() returns all data encryption keys in the key vault, with output similar to the following:返回密钥库中的所有数据加密密钥,输出类似于以下内容:
