Worked on the openssl/openssl repository to enhance memory management and security in documentation and demo code. Focused on updating all relevant instances to use OSSL_PARAM_clear_free() in place of OSSL_PARAM_free(), this change ensures that sensitive memory is properly cleared before being freed, reducing potential security risks. The work involved careful review and modification of C code, with attention to both technical accuracy and clarity in documentation. Collaborated with reviewers to validate the approach and confirm adherence to best practices. Utilized skills in C programming, documentation, and memory management to deliver a targeted improvement in secure resource handling.
