Python client for go-license license verification

python-licverify

Python client for 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

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

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:

licverify --public-key public.pem --license license.lic

Exit status 0 ⇒ valid, status 1 ⇒ invalid.
