Libwebsockets and included programs are provided under the terms of the
MIT license shown below, with the exception that some sources are under
a similar permissive license like BSD, or are explicitly CC0 / public
domain to remove any obstacles from basing differently-licensed code on
them.
Original liberal license retained:
- lib/misc/sha-1.c - 3-clause BSD license retained, link to original [BSD3]
- win32port/zlib - ZLIB license (see zlib.h) [ZLIB]
- lib/tls/mbedtls/wrapper - Apache 2.0 (only built if linked against mbedtls) [APACHE2]
lib/tls/mbedtls/mbedtls-extensions.c
- lib/misc/base64-decode.c - already MIT
- lib/misc/ieeehalfprecision.c - 2-clause BSD license retained [BSD2]
Relicensed to MIT:
- lib/misc/daemonize.c - relicensed from Public Domain to MIT,
link to original Public Domain version
- lib/plat/windows/windows-resolv.c - relicensed from "Beerware v42" to MIT
Public Domain (CC-zero) to simplify reuse:
- test-apps/*.c
- test-apps/*.h
- minimal-examples/*
- lwsws/*
Although libwebsockets is available under a permissive license, it does not
change the reality of dealing with large lumps of external code... if your
copy diverges it is guaranteed to contain security problems after a while
and can be very painful to pick backports (especially since historically,
we are very hot on cleaning and refactoring the codebase). The least
painful and lowest risk way remains sending your changes and fixes upstream
to us so you can easily use later releases and fixes.

Your contribution of software and/or data to Slicer (including prior
to the date of the first publication of this Agreement, each a
"Contribution") and/or downloading, copying, modifying, displaying,
distributing or use of any software and/or data from Slicer
(collectively, the "Software") constitutes acceptance of all of the
terms and conditions of this Agreement. If you do not agree to such
terms and conditions, you have no right to contribute your
Contribution, or to download, copy, modify, display, distribute or use
the Software.
PART A. CONTRIBUTION AGREEMENT - License to Brigham with Right to
Sublicense ("Contribution Agreement").
1. As used in this Contribution Agreement, "you" means the individual
contributing the Contribution to Slicer and the institution or
entity which employs or is otherwise affiliated with such
individual in connection with such Contribution.
2. This Contribution Agreement applies to all Contributions made to
Slicer, including without limitation Contributions made prior to
the date of first publication of this Agreement. If at any time you
make a Contribution to Slicer, you represent that (i) you are
legally authorized and entitled to make such Contribution and to
grant all licenses granted in this Contribution Agreement with
respect to such Contribution; (ii) if your Contribution includes
any patient data, all such data is de-identified in accordance with
U.S. confidentiality and security laws and requirements, including
but not limited to the Health Insurance Portability and
Accountability Act (HIPAA) and its regulations, and your disclosure
of such data for the purposes contemplated by this Agreement is
properly authorized and in compliance with all applicable laws and
regulations; and (iii) you have preserved in the Contribution all
applicable attributions, copyright notices and licenses for any
third party software or data included in the Contribution.
3. Except for the licenses granted in this Agreement, you reserve all
right, title and interest in your Contribution.
4. You hereby grant to Brigham, with the right to sublicense, a
perpetual, worldwide, non-exclusive, no charge, royalty-free,
irrevocable license to use, reproduce, make derivative works of,
display and distribute the Contribution. If your Contribution is
protected by patent, you hereby grant to Brigham, with the right to
sublicense, a perpetual, worldwide, non-exclusive, no-charge,
royalty-free, irrevocable license under your interest in patent
rights covering the Contribution, to make, have made, use, sell and
otherwise transfer your Contribution, alone or in combination with
any other code.
5. You acknowledge and agree that Brigham may incorporate your
Contribution into Slicer and may make Slicer available to members

Agreement. You further acknowledge and agree that Brigham shall
have no liability arising in connection with claims resulting from
your breach of any of the terms of this Agreement.
6. YOU WARRANT THAT TO THE BEST OF YOUR KNOWLEDGE YOUR CONTRIBUTION
DOES NOT CONTAIN ANY CODE THAT REQURES OR PRESCRIBES AN "OPEN
SOURCE LICENSE" FOR DERIVATIVE WORKS (by way of non-limiting
example, the GNU General Public License or other so-called
"reciprocal" license that requires any derived work to be licensed
under the GNU General Public License or other "open source
license").

Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer exclusive Copyright and Related Rights (defined below) upon the creator and subsequent owner(s) (each and all, an "owner") of an original work of authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for the purpose of contributing to a commons of creative, cultural and scientific works ("Commons") that the public can reliably and without fear of later claims of infringement build upon, modify, incorporate in other works, reuse and redistribute as freely as possible in any form whatsoever and for any purposes, including without limitation commercial purposes. These owners may contribute to the Commons to promote the ideal of a free culture and the further production of creative, cultural and scientific works, or to gain reputation or greater distribution for their Work in part through the use and efforts of others.
For these and/or other purposes and motivations, and without any expectation of additional consideration or compensation, the person associating CC0 with a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and publicly distribute the Work under its terms, with knowledge of his or her Copyright and Related Rights in the Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be protected by copyright and related or neighboring rights ("Copyright and Related Rights"). Copyright and Related Rights include, but are not limited to, the following:
the right to reproduce, adapt, distribute, perform, display, communicate, and translate a Work;
moral rights retained by the original author(s) and/or performer(s);
publicity and privacy rights pertaining to a person's image or likeness depicted in a Work;
rights protecting against unfair competition in regards to a Work, subject to the limitations in paragraph 4(a), below;
rights protecting the extraction, dissemination, use and reuse of data in a Work;
database rights (such as those arising under Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, and under any national implementation thereof, including any amended or successor version of such directive); and
other similar, equivalent or corresponding rights throughout the world based on applicable law or treaty, and any national implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention of, applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and unconditionally waives, abandons, and surrenders all of Affirmer's Copyright and Related Rights and associated claims and causes of action, whether now known or unknown (including existing as well as future claims and causes of action), in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each member of the public at large and to the detriment of Affirmer's heirs and successors, fully intending that such Waiver shall not be subject to revocation, rescission, cancellation, termination, or any other legal or equitable action to disrupt the quiet enjoyment of the Work by the public as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason be judged legally invalid or ineffective under applicable law, then the Waiver shall be preserved to the maximum extent permitted taking into account Affirmer's express Statement of Purpose. In addition, to the extent the Waiver is so judged Affirmer hereby grants to each affected person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and unconditional license to exercise Affirmer's Copyright and Related Rights in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "License"). The License shall be deemed effective as of the date CC0 was applied by Affirmer to the Work. Should any part of the License for any reason be judged legally invalid or ineffective under applicable law, such partial invalidity or ineffectiveness shall not invalidate the remainder of the License, and in such case Affirmer hereby affirms that he or she will not (i) exercise any of his or her remaining Copyright and Related Rights in the Work or (ii) assert any associated claims and causes of action with respect to the Work, in either case contrary to Affirmer's express Statement of Purpose.
4. Limitations and Disclaimers.
No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.
Affirmer offers the Work as-is and makes no representations or warranties of any kind concerning the Work, express, implied, statutory or otherwise, including without limitation warranties of title, merchantability, fitness for a particular purpose, non infringement, or the absence of latent or other defects, accuracy, or the present or absence of errors, whether or not discoverable, all to the greatest extent permissible under applicable law.
Affirmer disclaims responsibility for clearing rights of other persons that may apply to the Work or any use thereof, including without limitation any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims responsibility for obtaining any necessary consents, permissions or other rights required for any use of the Work.
Affirmer understands and acknowledges that Creative Commons is not a party to this document and has no duty or obligation with respect to this CC0 or use of the Work.
