PROFILE
Daniel Van Geest
Daniel van Geest contributed to the openssl/openssl repository by engineering cryptographic features and reliability improvements using C and OpenSSL provider development. He implemented CMS support for SHAKE-based digests and enhanced AlgorithmIdentifier compliance, enabling post-quantum digest strategies. Daniel delivered RFC-compliant HKDF and KEMRecipientInfo support, expanding cryptographic agility and user control. He improved decoder prioritization logic, ensuring correct algorithm selection across providers, and extended test coverage for property queries. Addressing CI and RNG issues, he aligned test data formats and library context usage for randomness. His work demonstrated depth in cryptography, CMS, and security engineering, consistently strengthening interoperability and standards compliance.

Jun 1, 2025June 2025: OpenSSL repository contributions focusing on decoder prioritization, reliability, and test coverage. Implemented a scoring mechanism to select the highest-scoring decoder when multiple providers support the same algorithm, improving correctness and runtime behavior. Updated the fake_rsa test provider to support encoding/decoding, expanding test coverage. Added a test validating adherence to property query strings, increasing reliability and user-facing correctness. Key commit: decoders: Fix prioritization of decoders via property query (60775e31123e6ef66a7cf86f199289d6e250dceb).
