This project is based on qhexedit2capstone and keystone engines. New features could be added in the future, PRs are welcomed.

Please note that in chunk mode, all the operations (e.g. search) applies only to the current chunk except for file save (the entire file is saved). However, each time you edit a chunk, save it before to move to another chunk, otherwise you will lose your changes.
  • Search and replace (UTF-8, HEX, regex, reverse search supported) [CTRL + F]
  • Colored output (white spaces, ASCII characters, 0xFF, UTF-8 and NULL bytes have different colors)
  • Interpret selected bytes as integer, long, unsigned long [CTRL + B]
  • Copy & Paste [CTRL + C and CTRL + V]
  • Copy selected unicode characters [CTRL + Space]
  • Zeroing all the selected bytes [Delete or CTRL + D]
  • Undo & Redo [CTRL + Z and CTRL + Y]
  • Drag & Drop....
