Worked on the openssl/openssl repository to deliver hardware-accelerated cryptographic operations for SHA-512 and SM3 by leveraging the RISC-V Vector Crypto Extension. Focused on low-level programming and performance optimization, the work involved implementing vectorized cryptographic routines in Assembly and integrating them with OpenSSL’s codebase. Benchmarks on the Xuantie C930 FPGA with VLEN256 demonstrated substantial throughput improvements, directly benefiting TLS and encryption workloads by increasing throughput and reducing latency. The contributions enhanced performance portability for RISC-V platforms, enabling scalable security workloads. The technical approach emphasized cross-architecture optimization, utilizing Assembly, Perl, and YAML to achieve efficient cryptographic acceleration.
