PROFILE
Christopher Patton
Over two months, Chris Patton contributed to the cloudflare/boring repository by engineering features that simplify cryptographic configuration and strengthen security defaults. He overhauled FIPS feature management and improved build reliability, particularly for environments using precompiled BoringSSL, leveraging Rust and C for robust system programming. Chris streamlined the TLS API by removing obsolete key exchange features and refactoring curve handling, exposing curve IDs directly for better observability. He enabled post-quantum cryptography by default, aligning with evolving security policies while maintaining flexibility. His work demonstrated depth in API design, build system configuration, and cryptography, resulting in cleaner interfaces and more reliable deployments.

Sep 1, 2025September 2025 monthly summary for cloudflare/boring: Delivered three key feature initiatives that simplify usage, improve TLS API clarity, and strengthen default cryptography, with direct code changes and accompanying tests. Key features delivered: - API surface simplification and cleanup: removed unused default kx-* features and obsolete FIPS-related comments to simplify the TLS API and reduce maintenance risk. - TLS curve API overhaul: removed the SslCurve API and reintroduced the curve() method on SslRef to expose the curve ID, including tests. - PQ cryptography enabled by default: removed the pq-experimental flag and enabled PQ cryptography by default across the project, with an override available. Impact and outcomes: - Reduced API surface and clearer TLS API surface, enabling easier onboarding and lower risk of misconfiguration. - Improved observability and interoperability through explicit access to the curve ID on SslRef. - Strengthened security posture by enabling PQ cryptography by default, with opt-out preserves flexibility for specialized work. Technical and business value: - Cleaner API reduces long-term maintenance costs and accelerates feature iteration. - Tests accompanying the curve API change help prevent regressions and support reliable deployments. - Default PQ cryptography aligns with security policy goals, improving baseline crypto strength for users.
