+ Provides access to KMS key data with Google Cloud KMS.

+
+# google\_kms\_crypto\_key
+
+Provides access to a Google Cloud Platform KMS CryptoKey. For more information see
+[the official documentation](https://cloud.google.com/kms/docs/object-hierarchy#key)
+and
+[API](https://cloud.google.com/kms/docs/reference/rest/v1/projects.locations.keyRings.cryptoKeys).
+
+A CryptoKey is an interface to key material which can be used to encrypt and decrypt data. A CryptoKey belongs to a
+Google Cloud KMS KeyRing.
+
+## Example Usage
+
+```hcl
+data "google_kms_key_ring" "my_key_ring" {
+  name     = "my-key-ring"
+  location = "us-central1"
+}
+
+data "google_kms_crypto_key" "my_crypto_key" {
+  name            = "my-crypto-key"
+  key_ring        = "${data.google_kms_key_ring.my_key_ring.self_link}"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The CryptoKey's name.
+    A CryptoKey’s name belonging to the specified Google Cloud Platform KeyRing and match the regular expression `[a-zA-Z0-9_-]{1,63}`
+
+* `key_ring` - (Required) The `self_link` of the Google Cloud Platform KeyRing to which the key belongs.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are
+exported:
+
+* `rotation_period` - Every time this period passes, generate a new CryptoKeyVersion and set it as
+    the primary. The first rotation will take place after the specified period. The rotation period has the format
+    of a decimal number with up to 9 fractional digits, followed by the letter s (seconds).
+
+* `self_link` - The self link of the created CryptoKey. Its format is `projects/{projectId}/locations/{location}/keyRings/{keyRingName}/cryptoKeys/{cryptoKeyName}`.
+

+A KeyRing is a grouping of CryptoKeys for organizational purposes. A KeyRing belongs to a Google Cloud Platform Project
+and resides in a specific location.
+
+## Example Usage

+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The KeyRing's name.
+    A KeyRing name must exist within the provided location and match the regular expression `[a-zA-Z0-9_-]{1,63}`
+
+* `location` - (Required) The Google Cloud Platform location for the KeyRing.
+    A full list of valid locations can be found by running `gcloud kms locations list`.
+
+- - -
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are
+exported:
+
+* `self_link` - The self link of the created KeyRing. Its format is `projects/{projectId}/locations/{location}/keyRings/{keyRingName}`.
