Question

我正在尝试创建一个KSM密钥以在S3服务中使用它，但我得到了MalformedPolicyDocument异常。这是资源：

"CustomerMasterKey":{
  "Type" : "AWS::KMS::Key",
  "Condition" : "EnableEncryption",
  "Properties" : {
    "Description" : "Client Master Key used to encrypt data",
    "Enabled" : true,
    "EnableKeyRotation" : true,
    "KeyPolicy" :
    {
      "Version": "2012-10-17",
      "Id": {"Fn::Join": ["",["Key","Policy",{"Ref": "CustomerParam"}]]},
      "Statement":
      [{
      "Sid": "Allow access for Key Administrators",
      "Effect": "Allow",
      "Principal": {
        "AWS": {"Fn::Join": ["",["arn:aws:iam::",{"Ref": "AWS::AccountId"},"moimeco"]]}
      },
      "Action": [
        "kms:Create*",
        "kms:Describe*",
        "kms:Enable*",
        "kms:List*",
        "kms:Put*",
        "kms:Update*",
        "kms:Revoke*",
        "kms:Disable*",
        "kms:Get*",
        "kms:Delete*",
        "kms:TagResource",
        "kms:UntagResource",
        "kms:ScheduleKeyDeletion",
        "kms:CancelKeyDeletion"
      ],
      "Resource": "*"
      },
      {
      "Sid": "Allow use of the key",
      "Effect": "Allow",
      "Principal": {
        "AWS":
        [
          {"Fn::Join": ["",["arn:aws:iam::",{"Ref": "AWS::AccountId"}, {"Ref": "CustomerParam"}]]},
          {"Fn::Join": ["",["arn:aws:iam::",{"Ref": "AWS::AccountId"},"userprod"]]}
        ]
      },
      "Action": [
        "kms:Encrypt",
        "kms:Decrypt",
        "kms:ReEncrypt*",
        "kms:GenerateDataKey*",
        "kms:DescribeKey"
      ],
      "Resource": "*",
      "Condition": {
        "StringEquals": {
          "kms:ViaService": "s3.eu-west-1.amazonaws.com"
        }
      }
      }]
    }
  }
},

我不知道错误在哪里，对我来说这一切都很好。好吗？

此代码给出了同样的错误：

定义的主体不会评估为Arns。

第一位委托人将评估为：

"AWS": "arn:aws:iam::11111111moimeco"

用户的有效ARN如下所示：

"arn:aws:iam::1111111:user/username"

此外，您需要将root用户包含在您的主体中。

否则，AWS根本不允许您创建密钥。这背后的原因如下所述：

“允许访问AWS账户并启用IAM策略”下的

AWS Key policies

创建AWS :: KSM :: Key时出现MalformedPolicyDocumentException
