> GCP HSM Integration Issues in Ranger KMS
>
> The integration of GCP HSM with Ranger KMS was failing due to the following
> issues:
>
> 1. Missing Dependencies
>
> Required dependencies such as protobuf-java, failureaccess, and guava were
> not included, causing compatibility issues with GCP libraries.
>
> Resolution:
>
> Added the missing dependencies (Guava, failureaccess, protobuf-java) to the
> project.
> Updated the KMS assembly configuration to ensure all required dependencies
> are packaged correctly.
>
> 2. Unconditional Master Key Creation Attempts
>
> The system was repeatedly attempting to call create master key even when it
> already existed. This led to unnecessary exceptions and instability.
>
> Additionally, the logic did not differentiate between user roles:
>
> Owner role → has permission to create a master key
> Viewer role → has permission to read/view the master key only
>
> However, both roles were attempting to generate the master key, which caused
> permission-related failures.
>
> Resolution:
>
> Introduced a masterKeyExists() check in the GCP HSM provider.
> Updated the logic to:
> First verify whether the master key already exists.
> Avoid call for creating the key if it already exists.
> Ensure that:
> Owner role can create the master key if it does not exist.
> Viewer role only checks for the existence of the master key and does not
> attempt creation.
