HexTool is a GNU GPL Windows (Win95/98/NT/2000/XP) application to provide hexadecimal, decimal and binary number manipulation.
The latest version of HexTool now contains IP address fields and an endian flip button.
Starting HexTool with a command line option, eg, "hextool 1" will force it to start in Advanced mode. The user can toggle between simple mode and advanced mode using the Maximise/Restore button.
The latest version of HexTool is hosted on SourceForge. You can get the latest CVS snapshot from there, or download the latest official release by following the links below:
