Spec score 7.2 #25 of 32 in Hex Editors

What it is

Hextor is a free Windows hexadecimal editor and toolkit for analyzing binary data. It can present content as text, hexadecimal, integer, or floating-point values, and can interpret or edit data through C-like structure descriptions. Search and replace supports text, hex, Unicode, wildcards, and value searches. Binary comparison detects inserted and deleted data. Hextor can view and edit logical volumes, physical disks, and process memory. Analysis features include bitmap viewing, MD, SHA, and CRC hash calculation, plus a disassembler using the Zydis library. Scripting works through IActiveScript. Version 0.15 adds partial, view-only Intel HEX support and searches involving an unknown half-byte. The Freeware plan costs nothing and allows personal and commercial use. Source code is available only for review. The project advises caution and backups for valuable data, provides no warranty, and disclaims liability for damage from use.
