PROFILE
Wyatt O'day
Wyatt contributed to the curl/curl repository by enhancing TLS security and reliability across Windows and mbedTLS backends. He stabilized Windows TLS negotiation by delegating ciphersuite selection to SChannel, reducing platform inconsistencies and simplifying code maintenance. For mbedTLS, Wyatt improved security posture by cleaning deprecated code, refining TLS version handling, and aligning cryptographic standards, including the removal of weak SHA1 certificates and RSA-1024 keys. His work also introduced modular random number generation and improved thread safety, leveraging C programming, network security, and multi-threading expertise. These changes addressed brittle behaviors and strengthened both the reliability and maintainability of curl’s TLS stack.

Nov 1, 2024Month: 2024-11 — Stabilized Windows TLS negotiation in curl by removing TLS 1.3 ciphersuite-list support from the Schannel path and delegating ciphersuite negotiation to SChannel. This reduces cross-platform inconsistencies, mitigates brittle behavior, and improves reliability for Windows deployments.
