Worked on the joernio/ghidra repository to enhance the display of PNG CRC32 metadata by formatting the checksum as a hexadecimal string prefixed with 0x, aligning with common hex conventions. This feature, implemented in Java, focused on improving data representation and file format analysis, making the output clearer for both developers and automated tooling. The change was delivered through a single, well-scoped commit with clear documentation, minimizing risk and maintaining project stability. No major bugs were addressed during this period, and the update contributed to more consistent and readable data presentation, facilitating easier debugging and integration with existing workflows.
