Hello Matthew Nakama,
Thanks for posting your question in the Microsoft Q&A forum.
You would need to:
- Develop a custom application or script that can authenticate to Azure Key Vault using appropriate credentials and retrieve keys from Azure Key Vault, and pass those keys to the AIX or IBM i encryption tools.
- Ensure secure communication between your on-premises systems and Azure Key Vault, likely involving VPN or ExpressRoute connections.
- Implement proper key rotation and management practices that work with both Azure Key Vault and your AIX/IBM i systems.
