Using key generators poses severe security threats, legal liabilities, and operational risks. How Cisco ASA Licensing Works

Creating, distributing, or using such generators would violate Cisco’s End User License Agreement (EULA), as well as intellectual property laws in most jurisdictions (such as the Digital Millennium Copyright Act in the U.S. or similar laws worldwide).
