During November 2025, Marius updated the SHA-256 hash for the Witch App in the Homebrew/homebrew-cask repository, focusing on enhancing download integrity and authenticity for end users. By implementing cryptographic hash verification and aligning repository documentation with security best practices, Marius reduced the risk of tampered installations and reinforced trust in package management workflows. The work involved using Ruby for cask configuration, leveraging Git for version control, and applying DevOps principles to maintain repository hygiene. While the scope was limited to a single feature, the update addressed a core security concern and demonstrated careful attention to validation and secure software distribution.
