Binary Diff

Binary diff is a tool or technique used to compare two binary files and identify differences between them at the byte level. It is essential for tasks like reverse engineering, malware analysis, software patching, and debugging compiled programs. Unlike text-based diff tools, it operates on raw binary data, making it crucial for low-level software work.

Also known as: BinDiff, Binary Comparison, Byte-level Diff, Hex Diff, Binary Patch

Why learn Binary Diff?

Developers should learn binary diff when working with compiled code, such as in reverse engineering to analyze malware or proprietary software, or when creating patches for binary files without source code access. It is also vital for firmware analysis, game modding, and verifying the integrity of binary distributions by comparing checksums or byte patterns.
