+  Get information on a AWS Key Management Service (KMS) Custom Key Store
+---
+
+# Data Source: aws_kms_custom_key_store
+
+Use this data source to get the metadata KMS custom key store.
+By using this data source, you can reference KMS custom key store
+without having to hard code the ID as input.
+
+## Example Usage
+
+```terraform
+data "aws_kms_custom_key_store" "keystore" {
+  name = "my_cloudhsm"
+}
+```
+
+## Argument Reference
+
+* `name` - (Optional) The user-specified friendly name for the custom key store.
+* `id` - (Optional) The ID for the custom key store.
+
+## Attributes Reference
+
+* `cloudhsm_cluster_id` - ID for the CloudHSM cluster that is associated with the custom key store.
+* `connection_state` - Indicates whether the custom key store is connected to its CloudHSM cluster.
+* `creation_date` - The date and time when the custom key store was created.
+* `trust_anchor_certificate` - The trust anchor certificate of the associated CloudHSM cluster.
