+
+# google_kms_crypto_key_version_latest
+
+Provides access to a Google Cloud Platform KMS Latest CryptoKeyVersion. For more information see
+[the official documentation](https://cloud.google.com/kms/docs/object-hierarchy#key_version)
+and
+[API](https://cloud.google.com/kms/docs/reference/rest/v1/projects.locations.keyRings.cryptoKeys.cryptoKeyVersions).
+
+A CryptoKeyVersion represents an individual cryptographic key, and the associated key material. Multiple CryptoKeyVersions can
+exist within one CryptoKey. This data source allows the ability to use the latest CryptoVersion from a specified CryptoKey.
+
+## 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.id
+}
+
+data "google_kms_crypto_key_version_latest" "my_crypto_key_version_latest" {
+  crypto_key = data.google_kms_crypto_key.my_key.id
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `crypto_key` - (Required) The `id` of the Google Cloud Platform CryptoKey to which the key version belongs. This is also the `id` field of the 
+`google_kms_crypto_key` resource/datasource.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are
+exported:
+
+* `id` - an identifier for the resource with format `//cloudkms.googleapis.com/v1/{{crypto_key}}/cryptoKeyVersions/{{version}}`
+
+* `name` - The resource name for this CryptoKeyVersion in the format `projects/*/locations/*/keyRings/*/cryptoKeys/*/cryptoKeyVersions/*`
+
+* `state` - The current state of the CryptoKeyVersion. See the [state reference](https://cloud.google.com/kms/docs/reference/rest/v1/projects.locations.keyRings.cryptoKeys.cryptoKeyVersions#CryptoKeyVersion.CryptoKeyVersionState) for possible outputs.
+
+* `protection_level` - The ProtectionLevel describing how crypto operations are performed with this CryptoKeyVersion. See the [protection_level reference](https://cloud.google.com/kms/docs/reference/rest/v1/ProtectionLevel) for possible outputs.
+
+* `algorithm` - The CryptoKeyVersionAlgorithm that this CryptoKeyVersion supports. See the [algorithm reference](https://cloud.google.com/kms/docs/reference/rest/v1/CryptoKeyVersionAlgorithm) for possible outputs.
+
+* `public_key` -  If the enclosing CryptoKey has purpose `ASYMMETRIC_SIGN` or `ASYMMETRIC_DECRYPT`, this block contains details about the public key associated to this CryptoKeyVersion. Structure is [documented below](#nested_public_key).
+
+<a name="nested_public_key"></a>The `public_key` block, if present, contains:
+
+* `pem` - The public key, encoded in PEM format. For more information, see the RFC 7468 sections for General Considerations and Textual Encoding of Subject Public Key Info.
+
+* `algorithm` - The CryptoKeyVersionAlgorithm that this CryptoKeyVersion supports.
