PROFILE

Ari Weiler-ofek

Worked on cryptographic feature development and codebase maintenance across the duckdb/mbedtls, espressif/TF-PSA-Crypto, and Mbed-TLS/mbedtls-framework repositories, focusing on security, reliability, and maintainability. Delivered AES-CBC PBES2 encryption support and comprehensive test datasets, using C and Makefile to expand cryptographic coverage and automate validation. Enhanced documentation and test scripts to clarify PSA Crypto API usage and align test expectations, improving onboarding and CI stability. Removed obsolete PKCS12 modules to streamline code and reduce maintenance overhead. Hardened PKCS#8 and PKCS#5 parsing tests, addressing edge cases and compatibility, and ensured dependencies remained current for robust embedded systems development.
