PROFILE
Willy Zhang
Contributed to the lowRISC/opentitan repository by expanding cryptographic capabilities and improving backend tooling over a two-month period. Developed and integrated MLDSA support into hsmtool, enabling generation, export, signing, and verification of MLDSA keys with domain-level configuration and proper OID handling for certificate signing requests. Updated cryptoki libraries to maintain compatibility with upstream APIs, reducing integration risk for downstream projects. Enhanced code quality by refactoring MLDSA algorithm input to use enums, centralizing key encoding and decoding logic, and applying consistent formatting and documentation standards. Worked primarily in Rust and Python, focusing on cryptography, API integration, and command line tool development.

Feb 1, 2026February 2026 monthly summary for lowRISC/opentitan focused on MLDSA integration in hsmtool and code quality improvements. Delivered MLDSA cryptography support for hsmtool, enabling encoding/decoding of MLDSA keys via the ml_dsa crate, and updated PKCS#11 constants/attributes to recognize MLDSA. Refactored MLDSA algorithm input to use an enum and centralized MLDSA key encoding/decoding in a dedicated utility module. Enhanced documentation for all MLDSA commands and applied formatting/documentation standards for maintainability. Implemented broad readability improvements across the hsmtool module, including rustfmt formatting on MLDSA-related code.

Jan 1, 2026January 2026 monthly summary for lowRISC/opentitan focusing on expanding cryptographic capabilities and API compatibility. Delivered MLDSA support in hsmtool with domain configuration, enabling generation/export/sign/verify of MLDSA keys and proper CSR OID handling (default MLDSA-87). Updated cryptoki libraries to align with the latest API, removing local patches and ensuring smooth initialization with upstream changes. These efforts improve security capabilities, interoperability, and reduce integration risk for downstream projects.
