FAQ

Use Python 3 when you install licensing with pip. Use Python 2 / IronPython when you copy cryptolens_python2.py into an older application. Their available methods and parameters differ; the legacy implementation is not a copy of every Python 3 feature.
No. These pages list the methods this SDK exposes. If a Web API method has no Python wrapper, use its documented HTTP endpoint. For example, retrieving an existing customer secret requires GetCustomers; the Python SDK has no Customer.get_customers method.
Key.activate and Key.get_key verify the returned license signature. Your application still decides whether the license permits the requested work. See the license-check FAQ for product, feature, expiry, blocking and machine checks.
These links keep bookmarks to the earlier reference working. Low-level request and cryptography helpers are implementation details. Use the documented settings or the public methods below.
