Contributed to the hashcat/hashcat repository by focusing on repository hygiene and tooling enhancements. Addressed maintenance challenges by implementing a .gitignore rule to exclude macOS .DS_Store files, reducing accidental commits and repository clutter. Developed gitea2hashcat.py, a Python script that converts Gitea PBKDF2-HMAC-SHA256 password hashes into a format compatible with Hashcat, streamlining data conversion and supporting robust password hashing workflows. Leveraged skills in scripting, data conversion, and version control to improve interoperability with external authentication systems. These updates enhanced continuous integration reliability and simplified repository management, reflecting a practical approach to foundational engineering tasks within the project.
