Supported AutoIt versions

• JB01 AutoIT2

Installation

python3 -m pip install autoit-ripper

or, if you’d like to install the version from sources:

git clone https://github.com/nazywam/AutoIt-Ripper.git
cd AutoIt-Ripper
pip install .

Running

From a python script:

from autoit_ripper import extract, AutoItVersion
with open("sample.exe", "rb") as f:
    file_content = f.read()
# EA05 for v3.00+, EA06 for v3.26+
# Omitting `version` or passing None will try both versions
content_list = extract(data=file_content, version=AutoItVersion.EA06)

From the commandline:

autoit-ripper sample.exe out_directory
