\title Qt Licensing
\brief Information about licenses and licensing issues.
Qt is available under different licensing options designed to accommodate
the needs of our various users:
\list
\li Qt licensed under \e commercial licenses is appropriate for
development of proprietary/commercial software where you do not want
to share any source code with third parties or otherwise cannot
comply with the terms of the GNU LGPL version 3.
\li Qt licensed under the \l{GNU Lesser General Public License (LGPL)}
version 3 is appropriate for the development of Qt applications
provided you can comply with the terms and conditions of the GNU LGPL
version 3 (or GNU GPL version 3).
\li Qt components licensed under the \l{Qt Marketplace License Agreement}
are appropriate for the development of Qt applications commonly with
Qt software components licensed under the commercial or GNU LGPL
version 3 (or GNU GPL version 3) terms and conditions.
\endlist
Qt contains also \l {Third-Party Code Used in Qt}{third-party code} that is licensed
under specific open-source licenses from the original authors.
\note For open-source licensed Qt, some specific parts (modules) are not
available under the GNU LGPL version 3, but under the
\l {GNU General Public License (GPL)} instead.

\enddetails
For commercial licensees, all modules are available under a single, commercial Qt
license.
\l {Tools and utilities}{Qt tools and utilities} are available under commercial
licenses from The Qt Company. Alternatively, they are available under the terms of
the \l{GNU General Public License (GPL)} version 3, with \l{Qt GPL exception 1.0}.
\e {Qt documentation} is available under commercial licenses from
The Qt Company, and under the terms of the \l{GNU Free
Documentation License (FDL)} version 1.3, as published by the Free Software
Foundation.
\e {Qt examples} are available under commercial licenses from The Qt Company,
and under a \l{License of Qt examples}{BSD-3-clause} license.
\l {Qt Educational License}{Educational licenses} are available for students
and educators in qualified educational institutions or universities.

\section1 Third-Party Code in Qt
The following page documents the open-source licenses used in different
parts of Qt:

\li \l {Third-Party Code Used in Qt}
\endlist
\section1 Software Bill of Materials (SBOM)
Starting from Qt 6.8, Software Bill of Materials (SBOM) documents of
third-party components in Qt are available. Information such as copyrights,
licenses, versions, source repositories, and other relevant information are
declared in SPDX 2.3 format.
\list
\li \l {Software Bill of Materials}
\endlist
\section1 Export Controls
Many jurisdictions impose export controls for various hardware and software
products. In general, the mass-market Qt framework as well as the related
tools provided by the Qt Group do not contain functionality that would
cause them to be under tight regulations. The following page lists the
relevant information about export controls.

\title Third-Party Code Used in Qt
\brief Information about third-party code used in Qt.
Qt libraries and plugins can contain code that is not intellectual
property of The Qt Company, but is available under specific open-source
licenses from the original authors.
The Qt Company gratefully acknowledges these and other contributions to Qt.
We recommend that programs that use Qt also acknowledge these contributions
and quote these license statements in an appendix to the documentation.
\note You only need to acknowledge and comply with the licenses of the
third-party components that you are actually shipping with your
application. Click the name of the component to see the licensing details.
\b {Third-party Licenses}
The following sections list third-party components in Qt \QtVersion, grouped by
\l{All Modules}{Qt module}. If the third-party component itself consists of
parts that are of a different origin (so-called
4th-party or Nth-party code), these are listed, too.
Starting from Qt 6.8, Software Bill of Materials (SBOM) documents of
third-party components in Qt are available. Information such as copyrights,
licenses, versions, source repositories, and other relevant information are
declared in SPDX 2.3 format. For more information, visit the
\l {Software Bill of Materials} page.

This software was written by Alexander Peslyak in 2001. No copyright is

(This is a heavily cut-down "BSD license".)
This differs from Colin Plumb's older public domain implementation in that
no exactly 32-bit integer data type is required (any 32-bit or wider
unsigned integer data type will do), there's no compile-time endianness
configuration, and the function prototypes match OpenSSL's. No code from
Colin Plumb's implementation has been reused; this comment merely compares
the properties of the two independent implementations.
The primary goals of this implementation are portability and ease of use.
It is meant to be fast, but not as fast as possible. Some known
optimizations are not included to reduce source code size and avoid
compile-time configuration.
