Valentin Haerter developed security-focused enhancements for the THI-CSI/decentralized_iam_battery_data repository, building robust access control and encrypted data storage for the Battery Pass API. He implemented HPKE-based encryption, key management, and role-based access control using Python and FastAPI, migrating data to an encrypted TinyDB backend. Valentin expanded the API with a secure GET endpoint supporting scope-based permissions and Verifiable Presentations, while improving payload validation and cryptographic handling. He consolidated and clarified API documentation with Swagger, updated dependencies, and resolved configuration issues. His work strengthened data security, compliance, and developer experience, providing a solid technical foundation for secure battery data sharing.
