Inhabilita y habilita versiones de clave

Una versión de clave tiene un estado que determina si se puede usar para encriptación y desencriptación.

Para habilitar o inhabilitar una versión de clave, es necesario que un usuario tenga la función o el permiso adecuado de Cloud Identity and Access Management.

• Las funciones predefinidas roles/cloudkms.admin, roles/owner o roles/editor pueden habilitar o inhabilitar una versión de clave.

• Una función personalizada que contenga el permiso cloudkms.cryptoKeyVersions.update puede habilitar o inhabilitar una versión de clave.

Inhabilita una versión de clave habilitada

Solo se pueden inhabilitar las claves habilitadas. Para ello, utiliza el método UpdateCryptoKeyVersion con el campo state, los métodos de biblioteca cliente mapeados a UpdateCryptoKeyVersion, gcloud kms keys versions disable o Google Cloud Platform Console.

Nota: Cuando inhabilitas las versión de clave, aún puedes usarla para encriptar y desencriptar datos durante aproximadamente 40 minutos. Puede permanecer disponible para usarla en la encriptación y desencriptación de datos hasta por 3 horas.

Console

1. Ve a la página Claves criptográficas en GCP Console.
   Ir a la página Claves criptográficas
   

2. Haz clic en el nombre del llavero de claves que contiene la clave cuya versión se inhabilitará.

3. Haz clic en la clave cuya versión de clave deseas inhabilitar.

4. Haz clic en la versión de clave que deseas inhabilitar.

5. Haz clic en Inhabilitar.

6. Cuando se te solicite confirmar la inhabilitación de la versión de clave, haz clic en Inhabilitar.

Línea de comandos

Para inhabilitar la versión 42 de la clave answer del llavero de claves answers en la ubicación global, usa el siguiente comando:

gcloud kms keys versions disable 42 --location global \
  --keyring answers --key answer

Coherencia cuando se habilita o inhabilita una versión de clave

Habilitar una versión de clave es una operación de coherencia sólida. La versión de clave habilitada está disponible inmediatamente para la encriptación y desencriptación de datos. Inhabilitar una versión de clave es una operación de coherencia eventual. La versión de clave inhabilitada aún puede usarse para encriptar y desencriptar datos por 40 minutos, en promedio, y hasta por 3 horas. Para obtener más detalles sobre la coherencia de las versiones de clave, consulta Coherencia de recursos de Cloud KMS.
