All official builds from LineageOS are signed with our private keys. You can verify whether a build has been signed with our keys by following these steps:

{% include alerts/note.html content="To go ahead with the verification, `git`, `python3-pip`, and `python3` are required." %}

Download the verifier and install its dependencies:

```
git clone https://github.com/LineageOS/update_verifier
cd update_verifier
pip3 install -r requirements.txt
```

Check the signature of the downloaded ZIP file:

```
python3 update_verifier.py lineageos_pubkey /path/to/zip
```

If the script reports `verified successfully`, the ZIP file signature is valid.
