Rockstar🎓
Top SchoolDavid Hook is a veteran software engineering leader with 13 years in senior roles and a multi-decade background in cryptography, applied security and systems engineering from Melbourne. As VP Software Engineering at Keyfactor and long-time director of Crypto Workshop, he has led FIPS 140-2 certifications for Bouncy Castle on both Java and .NET and built privacy-preserving systems such as an EC threshold MixNet for anonymous e-voting. A hands-on maintainer of core cryptographic libraries (notably contributions to the Bouncy Castle Java and C# mirrors), he blends deep algorithmic and protocol knowledge with product architecture and team leadership. His career spans secure product delivery, patent-backed designs, and public speaking on post-quantum and FIPS topics—evidence of a practitioner who navigates both standards and cutting-edge research.
