# python-licverify
Python client for [go-license](https://github.com/luhtfiimanal/go-license) license verification.
`python-licverify` allows you to verify `.lic` files generated by the `licforge` CLI or Go library **entirely from Python**, including:
* RSA-SHA256 signature validation
* Hardware binding checks (MAC address, disk ID, hostname)
* Expiry validation
* Simple CLI utility
## Installation
```bash
pip install python-licverify # or uv pip install python-licverify
```
> Depend on `cryptography` and `psutil`. Wheels are provided for Python 3.12+, no extra build tools required.
## Usage
### Library API
```python
from licverify import Verifier
PUBLIC_KEY_PEM = open("public.pem").read()
verifier = Verifier(PUBLIC_KEY_PEM)
license = verifier.load_license("license.lic")
try:
license.verify(verifier) # raises on failure
except Exception as exc:
print(f"License invalid: {exc}")
else:
print("License is valid!")
```
### Command-line
After installation a `licverify` command is available:
```bash
licverify --public-key public.pem --license license.lic
```
Exit status 0 ⇒ valid, status 1 ⇒ invalid.
## Examples
See [`examples/basic_usage.py`](examples/basic_usage.py).
## Development
```bash
git clone https://github.com/luhtfiimanal/python-licverify
cd python-licverify
uv sync # install dev deps (optional)
uv run -m pip install -e .
```
Run tests (to be added soon):
```bash
pytest -q
```
