+# huaweicloud_kms_tags
+
+Use this data source to query the tag list of KMS within HuaweiCloud.
+
+## Example Usage
+
+```hcl
+data "huaweicloud_kms_tags" "test" {}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.  
+  If omitted, the provider-level region will be used.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `tags` - The list of the tags.  
+  The [tags](#kms_project_tags) structure is documented below.
+
+<a name="kms_project_tags"></a>
+The `tags` block supports:
+
+* `key` - The tag key.
+
+* `values` - The tag values.
