AutoIt Obfuscator Integration with SciTE

AutoIt is a scripting language for automating Windows tasks — from simple GUI macros to full desktop applications. Scripts are typically written in SciTE, the editor bundled with AutoIt.

AutoIt Decompilation

Compiled AutoIt executables still embed the original source code in an encrypted form.

With the right reverse engineering tools (aka decompilers), that code can be recovered, exposing variable names, strings, and program logic. Obfuscation transforms the source into a functionally equivalent but far harder-to-analyze version, making reverse engineering significantly more difficult.

AutoIt Obfuscation

**AutoIt Obfuscator is an advanced & battle-tested AutoIt obfuscator with years of development & testing. It now integrates directly with SciTE. When the integration option is selected during installation, the setup program updates %USERPROFILE%\SciTEUser.properties and adds an Obfuscate command to the Tools** menu.

Developers can then obfuscate *.au3 scripts with a single click, without leaving the editor.

Configuration changes

The installer appends the following block to the user configuration file:

### AutoItObfuscator Section Start

# Activate the obfuscator menu for *.au3 files only (* for all files)
command.name.11.*.au3=Obfuscate

# Setup your obfuscation parameters, enter your activation key, output path etc.

#
# overwrite existing file (SciTE will refresh the view, you can always undo with CTRL-Z)
#
command.11.*.au3=C:\Program Files (x86)\AutoIt Obfuscator\AutoItObfuscatorCmd.exe /InputFilePath="$(FilePath)" /OutputFilePath="$(FilePath)"
#command.11.*.au3=C:\Program Files (x86)\AutoIt Obfuscator\AutoItObfuscatorCmd.exe /ActivationCode="ENTER-YOUR-CODE-HERE" /InputFilePath="$(FilePath)" /OutputFilePath="$(FilePath)"

#
# create a new file
#
#command.11.*.au3=C:\Program Files (x86)\AutoIt Obfuscator\AutoItObfuscatorCmd.exe /InputFilePath="$(FilePath)" /OutputFilePath="$(FilePath).obfuscated.au3"

# Save any script before obfuscation (1 - save before obfuscation, 2 - use previously saved file content)
command.save.before.11.*.au3=1

# Specify the subsystem (0 Console, 2 = Windows GUI Executable / Web Link)
command.subsystem.11.*.au3=0

# Obfuscation command shortcut
command.shortcut.11.*.au3=Ctrl+F12

Customization

These settings can be edited in SciTE under Options → Open User Options File — for example, to adjust obfuscation parameters or add an activation key.
