Python tools for Keygen.sh licensing

keygen_licensing_tools

Some handy tools for the Keygen licensing service. (This is a user contribution, not an official Keygen LLC product. For Keygen software, see here.)

Install with

pip install keygen_licensing_tools

and use as

from keygen_licensing_tools import validate_license_key_online

out = validate_license_key_online(
    account_id="demo", key="DEMO-DAD877-FCBF82-B83D5A-03E644-V3"
)

if not out.is_valid:
    print(f"Error: Invalid license ({out.code}). Exiting.")
    exit(1)

The out object contains useful information such as

out.is_valid
out.code
out.timestamp
out.license_creation_time
out.license_expiry_time

The validation result can also be safely cached with

from datetime import datetime, timedelta
from keygen_licensing_tools import validate_license_key_cached

out = validate_license_key_cached(
    account_id="your accound id",
    key="the license key",
    keygen_verify_key="your Ed25519 128-bit Verify Key",
    cache_path="/tmp/license-cache.json",
    refresh_cache_period=timedelta(days=3),
)

if not out.is_valid:
    print(f"Error: Invalid license ({out.code}). Exiting.")
    exit(1)

now = datetime.utcnow()
cache_age = now - out.timestamp
if cache_age > timedelta(days=3) and cache_age < timedelta(days=7):
    print("Warning: Could not validate license. Make sure to get online soon.")
elif cache_age > timedelta(days=7):
    print("Error: Could not validate license. Internet connection needed. Exiting.")
    exit(1)
