Hextor

What Hextor is
Hextor is a Windows hexadecimal editor and toolkit for examining and editing binary data. It can display values as text, hexadecimal, integers, or floating-point numbers, and interpret or edit them with C-like structure descriptions. Search and replace cover text, hex, Unicode, wildcards, and values; binary comparison identifies insertions and deletions. Hextor can also access logical volumes, physical disks, and process memory for viewing and editing. Analysis tools include bitmap viewing, MD, SHA, and CRC hash calculation, plus a disassembler based on the Zydis library. Scripting is available through IActiveScript. Version 0.15 adds limited, view-only Intel HEX support and search for an unknown half-byte. The freeware license allows personal and commercial use at no cost, while source code is available for review only. The project advises caution and backups when working with valuable data. It comes without warranty, and the author disclaims liability for damage arising from use.
