Worked on the chipsalliance/Caliptra and chipsalliance/caliptra-sw repositories, focusing on documentation quality and cryptographic feature enhancements. Addressed broken README links by updating references to the correct hardware specification version, improving documentation accuracy and usability. Developed a flexible SHA input length feature in Rust, enabling precise hashing of partial data by trimming unused padding and supporting an optional data length parameter. Added comprehensive unit tests to validate hashing correctness across edge cases. Leveraged skills in cryptography, embedded systems, and documentation to drive cross-repository consistency, reduce friction for hardware specification access, and enhance the reliability of hashing workflows for embedded applications.
