Worked on the SkriptLang/Skript repository to enhance the stability and correctness of the scripting engine by addressing a bug related to MD5 deprecation warnings in the ExprHash component. The solution involved implementing conditional logic in Java to ensure that deprecation warnings for MD5 usage are only triggered when the parser is active, thereby reducing unnecessary runtime errors and clarifying cryptographic policy for users. This backend development effort improved the maintainability and safety of the warning system, demonstrating a focus on security best practices, parser debugging, and collaborative code review within a Java-based codebase dedicated to scripting engine reliability.
