Goal: 

To actually implement the adoption steps of a Proteccio HSM as a secure backend for the Barbican (Key Manager) service, migrating from a legacy RHOSP 17.1 environment to RHOSO 18.

Acceptance Criteria:

• Secure network connectivity is established and verified between the OpenStack Key Manager (Barbican) service pods and the Eviden Proteccio HSM.
• The Barbican service is configured with the PKCS#11 driver and successfully uses the Eviden Proteccio HSM as its cryptographic backend for all secret storage operations.

• End-to-end validation tests pass, confirming that secrets can be created, retrieved, and deleted via the Barbican API, with HSM-level logs verifying that all cryptographic functions are being processed by the hardware.
