additionalAuthenticatedData property
Optional data that, if specified, must also be provided during decryption through DecryptRequest.additional_authenticated_data.
The maximum size depends on the key version's protection_level. For SOFTWARE, EXTERNAL, and EXTERNAL_VPC keys the AAD must be no larger than 64KiB. For HSM keys, the combined length of the plaintext and additional_authenticated_data fields must be no larger than 8KiB.
Optional.
