# google\_kms\_crypto\_key
Allows creation of a Google Cloud Platform KMS CryptoKey. For more information see
[the official documentation](https://cloud.google.com/kms/docs/object-hierarchy#cryptokey)
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.
~> Note: CryptoKeys cannot be deleted from Google Cloud Platform. Destroying a Terraform-managed CryptoKey will remove it
from state and delete all CryptoKeyVersions, rendering the key unusable, but **will not delete the resource on the server**.
## Example Usage
```hcl
resource "google_kms_key_ring" "my_key_ring" {
name = "my-key-ring"
project = "my-project"
location = "us-central1"
}
resource "google_kms_crypto_key" "my_crypto_key" {
name = "my-crypto-key"
key_ring = "${google_kms_key_ring.my_key_ring.id}"
rotation_period = "100000s"
}
```
## Argument Reference
The following arguments are supported:
* `name` - (Required) The CryptoKey's name.
A CryptoKeys name must be unique within a location and match the regular expression `[a-zA-Z0-9_-]{1,63}`
* `key_ring` - (Required) The id of the Google Cloud Platform KeyRing to which the key shall belong.
- - -
* `rotation_period` - (Optional) 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). It must be greater than
a day (ie, 83400).
## Attributes Reference
In addition to the arguments listed above, the following computed attributes are
exported:
* `id` - The ID of the created CryptoKey. Its format is `{projectId}/{location}/{keyRingName}/{cryptoKeyName}`.
## Import
CryptoKeys can be imported using the CryptoKey autogenerated `id`, e.g.
```
$ terraform import google_kms_crypto_key.my_crypto_key my-gcp-project/us-central1/my-key-ring/my-crypto-key
$ terraform import google_kms_crypto_key.my_crypto_key us-central1/my-key-ring/my-crypto-key
```
