kmsKeyName property
[Preview] Resource name of a KMS crypto key (managed by the user) used to encrypt/decrypt function source code objects in intermediate Cloud Storage buckets.
When you generate an upload url and upload your source code, it gets
copied to an intermediate Cloud Storage bucket. The source code is then
copied to a versioned directory in the sources bucket in the consumer
project during the function deployment. It must match the pattern
projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}
.
The Google Cloud Functions service account
(service-{project_number}@gcf-admin-robot.iam.gserviceaccount.com) must be
granted the role 'Cloud KMS CryptoKey Encrypter/Decrypter
(roles/cloudkms.cryptoKeyEncrypterDecrypter)' on the
Key/KeyRing/Project/Organization (least access preferred).
