PROFILE
Elizarova, Alina
Worked on the openssl/openssl repository over three months, focusing on low-level performance enhancements for cryptographic workloads. Delivered hardware-accelerated SM3 and SM4 hashing and encryption on x86-64 by leveraging ISA extensions, writing assembly implementations for block processing, encryption, decryption, and key setup. Extended CPU feature detection by updating OPENSSL_ia32cap to support additional CPUID leaves, enabling broader use of advanced instruction sets. Integrated these optimizations across multiple cipher modes, improving throughput and reducing CPU usage for TLS and secure communications. Utilized Assembly, C, and Perl, applying expertise in CPU architecture, cryptography, and performance engineering to optimize OpenSSL for modern hardware.
