PROFILE

Miguel Herran

Over three months, Miguel Herranz enhanced the RIPE-NCC/whois repository by delivering seven features and resolving two bugs, focusing on reliability, security, and maintainability. He migrated legacy XML configuration to Java-based Spring configuration, improving type safety and modularity. Miguel refactored the RDAP entity data model and implemented cross-RIR reverse domain lookup redirection, supporting IPv4 and IPv6. He overhauled authentication by deprecating password-based methods in favor of PGP signing and API keys, strengthening security. Using Java, YAML, and the Spring Framework, Miguel’s work demonstrated depth in backend development, test automation, and secure deployment practices, resulting in a more robust codebase.

February 2026 — RIPE-NCC/whois: Security hardening and data-import reliability upgrades. Delivered an Authentication System Overhaul with a secure path forward (password deprecation, control flag to disable password auth, updated tests and error messaging, plus user guidance toward PGP signing or API keys). Implemented GRS Import Process Enhancements (better timestamp handling and warnings for outdated downloads) to improve data freshness and import reliability. Both initiatives reduce security risk, improve user experience, and bolster data integrity.
