Create a Python script that acts as a plugin.
import sys import clipboard # pip install clipboard Note: HXD copies raw hex bytes, not ASCII hex. This example assumes you copied bytes, not text. data = clipboard.paste() Simulate: Reverse byte order if isinstance(data, bytes): reversed_data = data[::-1] clipboard.copy(reversed_data) print("Reversed! Paste back into HXD.") else: print("Copy raw binary from HXD first.") hxd plugins
Is this a flaw? Not necessarily. Many security professionals argue that a hex editor should not run code embedded in files. A plugin system introduces attack surface. When you open a malicious file, you don't want your hex editor's plugin loader to be the vector. Create a Python script that acts as a plugin
However, a common question that arises when users try to push HXD to its limits is: data = clipboard
If you search for “HXD plugins,” you will find a confusing landscape. Unlike code editors like VS Code or IDEs like Eclipse, HXD does not have an official, documented SDK (Software Development Kit) or a dedicated plugin marketplace. But that does not mean you cannot extend its functionality.
Don't wait for HXD plugins. Learn to script the tool indirectly. Or, if you truly need a plugin architecture, migrate to ImHex immediately—it is the spiritual successor to HXD for power users.
