PROFILE
Miguel Herran
Worked on the RIPE-NCC/whois repository over three months, delivering seven features and two bug fixes focused on reliability, security, and maintainability. Introduced Java-based Spring configuration to replace XML, improving type safety and modularity. Enhanced deployment flexibility with environment variable support and refactored the RDAP entity data model for better encapsulation. Implemented cross-RIR reverse domain lookup redirection and overhauled authentication by deprecating password-based methods in favor of PGP signing or API keys. Improved GRS import reliability with better timestamp handling and diagnostics. Leveraged Java, YAML, and the Spring Framework, emphasizing backend development, security best practices, and automated testing throughout.

3 Commits • 2 Features
Feb 1, 2026February 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 Implemented GRS Import Process Enhancements (better timestamp handling and warnings for outdated downloads) to improve data freshness and import reliability.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.
