This page provides a list of Google Cloud services that offer integrations with Cloud KMS. These services generally fall under one of the following categories:
A Customer-managed encryption key (CMEK) integration lets you encrypt the data at rest in that service using a Cloud KMS key that you own and manage. Data protected with a CMEK key cannot be decrypted without access to that key.
A CMEK-compliant service either does not store data, or only stores data for a short period of time, such as during batch processing. Such data is encrypted using an ephemeral key that only exists in memory and is never written to disk. When the data is no longer needed, the ephemeral key is flushed from memory, and the data can't ever be accessed again. The output of a CMEK-compliant service might be stored in a service that is integrated with CMEK, such as Cloud Storage.
Your applications can use Cloud KMS in other ways. For example, you can directly encrypt application data before transmitting or storing it.

CMEK integrations
The following table lists services that integrate with Cloud KMS. All services in this list support software and hardware (HSM) keys. Products that integrate with Cloud KMS when using external Cloud EKM keys are indicated under EKM supported.
