* Nmap is generally free for end users to download and use themselves, *

* *
* The Nmap license generally prohibits companies from using and *
* redistributing Nmap in commercial products, but we sell a special Nmap *
* OEM Edition with a more permissive license and special features for *
* this purpose. See https://nmap.org/oem/ *
* *
* If you have received a written Nmap license agreement or contract *

* choose to use and redistribute Nmap under those terms instead. *
* *
* The official Nmap Windows builds include the Npcap software *
* (https://npcap.com) for packet capture and transmission. It is under *
* separate license terms which forbid redistribution without special *
* permission. So the official Nmap Windows builds may not be *

* license). *
* *
* Source is provided to this software because we believe users have a *
* right to know exactly what a program is going to do before they run it. *
* This also allows you to audit the software for security holes. *
* *
* Source code also allows you to port Nmap to new platforms, fix bugs, *
* and add new features. You are highly encouraged to submit your *
* changes as a Github PR or by email to the dev@nmap.org mailing list *
* for possible incorporation into the main distribution. Unless you *
* specify otherwise, it is understood that you are offering us very *
* broad rights to use your submissions as described in the Nmap Public *
* Source License Contributor Agreement. This is important because we *
* fund the project by selling licenses with various terms, and also *
* because the inability to relicense code has caused devastating *
* problems for other Free Software projects (such as KDE and NASM). *
