Worked on modernizing IP address handling in the hashcat/hashcat repository by replacing the deprecated inet_ntoa function with inet_ntop. This update improved compatibility with both IPv4 and IPv6, aligning the codebase with current networking standards and reducing future maintenance risks. The approach focused on enhancing cross-platform reliability for address parsing, ensuring that the software remains robust as networking APIs evolve. Utilizing C programming and network programming skills, the developer contributed a targeted feature that eliminates reliance on legacy APIs. The work addressed a specific technical debt, resulting in more maintainable and future-proof IP address management within the project.
