pySigMaker

An IDA Pro plugin to make creating code signatures quick and simple. This is a port of the popular (compiled) version of SigMaker-X64 with a new pyQt5 GUI that can be left open as a floating window or docked. The primary goal was to make a plugin that would work with many versions of IDA without needing to compile against the IDA SDK. Since the IDAPython API is now uniform in structure it seemed like a good time to tackle this project.

Credits to the author/contributors of SigMaker-x64 for the core sig generating code.

** Python 3.8 Recommended **

Updates:

2026-01-23 Added support for IDA v9, tested on 9.1  
2026-01-24 Changed bin_search flags for IDA 9  

Install:

copy pySigMaker.py into IDA plugin folder.

**Note** Default is to use same hotkey as SigMaker-x64 (Ctrl-Alt-S) which will 
         cause a warning to be displayed in IDA if orig SigMaker-x64 plugin 
         exists.  On settings tab there will be an option to archive the origional
         SigMaker-X64 plugins to a folder in IDA plugins dir.  Or you can 
         choose to change the hotkey.  This plugin will get priority if both exist
         and default hotkey is used.

Default hotkey:

• Ctrl + Alt + S

Confirmed working:

IDA Pro 7.0
IDA Pro 7.5, IDAPython 64-bit v7.4.0 final, Python 3.8 64 bit
IDA Pro 7.6
IDA Pro 9.1

Sig types supported:

IDA Patterns : E8 ? ? ? ? 48 8B 83 ? ? ? ? 48 8B CB
Olly Patterns: E8 ?? ?? ?? ?? 48 8B 83 ?? ?? ?? ?? 48 8B CB
Code Patterns: \xE8\x00\x00\x00\x00\x48\x8B x????xx (mask optional)

Bug fixes:

Fixed issue with rebased images (related to ida inf struct)

Changes:

1. Making a sig from selection was replaced with an auto-create at current address. 
2. Trailing wildcards on sigs are dropped
3. Added a new pyQt5 tabbed Gui that can be used in floating or docked modes.
4. LOG_ERROR is minimum output setting now so error messages are always output.
5. Improved history, mask automatically restored based on sig selected in drop down.
