- Decrypt
-
Si usó una clave administrada por el cliente de AWS KMS para cifrar el objeto de criterios de filtro, Lambda envía una solicitud Decrypt
en su nombre cuando intenta acceder a él en texto sin formato (por ejemplo, desde una llamada a ListEventSourceMappings
). El siguiente evento de ejemplo registra la operación Decrypt
:

Si usó una clave administrada por el cliente de AWS KMS para cifrar el objeto de criterios de filtro, Lambda envía una solicitud DescribeKey

- GenerateDataKey
-
Cuando utiliza una clave administrada por el cliente de AWS KMS para cifrar el objeto de criterios de filtro en una llamada a CreateEventSourceMapping
o UpdateEventSourceMapping
, Lambda envía una solicitud GenerateDataKey
en su nombre para generar una clave de datos para cifrar los criterios de filtro (cifrado de sobre). El siguiente evento de ejemplo registra la operación GenerateDataKey
:
