      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

BoringSSL is a fork of OpenSSL. As such, large parts of it fall under OpenSSL
licensing. Files that are completely new have a Google copyright and an ISC
license. This license is reproduced at the bottom of this file.

Contributors to BoringSSL are required to follow the CLA rules for Chromium:
https://cla.developers.google.com/clas

Files in third_party/ have their own licenses, as described therein. The MIT
license, for third_party/fiat, which, unlike other third_party directories, is
compiled into non-test libraries, is included below.

The OpenSSL toolkit stays under a dual license, i.e. both the conditions of the
OpenSSL License and the original SSLeay license apply to the toolkit. See below
for the actual license texts. Actually both licenses are BSD-style Open Source
licenses. In case of any license issues related to OpenSSL please contact
openssl-core@openssl.org.

The following are Google-internal bug numbers where explicit permission from
some authors is recorded for use of their work. (This is purely for our own
record keeping.)

      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

    2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

    3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

    4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

    5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

    6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

    7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

    8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

    9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

     "Object" form shall mean any form resulting from mechanical
     transformation or translation of a Source form, including but
     not limited to compiled object code, generated documentation,
     and conversions to other media types.

     "Work" shall mean the work of authorship, whether in Source or
     Object form, made available under the License, as indicated by a
     copyright notice that is included in or attached to the work
     (an example is provided in the Appendix below).

     "Derivative Works" shall mean any work, whether in Source or Object
     form, that is based on (or derived from) the Work and for which the
     editorial revisions, annotations, elaborations, or other modifications
     represent, as a whole, an original work of authorship. For the purposes
     of this License, Derivative Works shall not include works that remain
     separable from, or merely link (or bind by name) to the interfaces of,
     the Work and Derivative Works thereof.

     "Contribution" shall mean any work of authorship, including
     the original version of the Work and any modifications or additions
     to that Work or Derivative Works thereof, that is intentionally
     submitted to Licensor for inclusion in the Work by the copyright owner
     or by an individual or Legal Entity authorized to submit on behalf of
     the copyright owner. For the purposes of this definition, "submitted"
     means any form of electronic, verbal, or written communication sent
     to the Licensor or its representatives, including but not limited to
     communication on electronic mailing lists, source code control systems,
     and issue tracking systems that are managed by, or on behalf of, the

     designated in writing by the copyright owner as "Not a Contribution."

     "Contributor" shall mean Licensor and any individual or Legal Entity
     on behalf of whom a Contribution has been received by Licensor and
     subsequently incorporated within the Work.

  2. Grant of Copyright License. Subject to the terms and conditions of
     this License, each Contributor hereby grants to You a perpetual,
     worldwide, non-exclusive, no-charge, royalty-free, irrevocable
     copyright license to reproduce, prepare Derivative Works of,
     publicly display, publicly perform, sublicense, and distribute the
     Work and such Derivative Works in Source or Object form.

  3. Grant of Patent License. Subject to the terms and conditions of
     this License, each Contributor hereby grants to You a perpetual,
     worldwide, non-exclusive, no-charge, royalty-free, irrevocable
     (except as stated in this section) patent license to make, have made,
     use, offer to sell, sell, import, and otherwise transfer the Work,
     where such license applies only to those patent claims licensable
     by such Contributor that are necessarily infringed by their
     Contribution(s) alone or by combination of their Contribution(s)
     with the Work to which such Contribution(s) was submitted. If You
     institute patent litigation against any entity (including a
     cross-claim or counterclaim in a lawsuit) alleging that the Work
     or a Contribution incorporated within the Work constitutes direct
     or contributory patent infringement, then any patent licenses
     granted to You under this License for that Work shall terminate
     as of the date such litigation is filed.

  4. Redistribution. You may reproduce and distribute copies of the
     Work or Derivative Works thereof in any medium, with or without
     modifications, and in Source or Object form, provided that You
     meet the following conditions:

     (a) You must give any other recipients of the Work or
         Derivative Works a copy of this License; and

     (b) You must cause any modified files to carry prominent notices
         stating that You changed the files; and

     (c) You must retain, in the Source form of any Derivative Works
         that You distribute, all copyright, patent, trademark, and
         attribution notices from the Source form of the Work,
         excluding those notices that do not pertain to any part of
         the Derivative Works; and

     (d) If the Work includes a "NOTICE" text file as part of its
         distribution, then any Derivative Works that You distribute must
         include a readable copy of the attribution notices contained
         within such NOTICE file, excluding those notices that do not
         pertain to any part of the Derivative Works, in at least one
         of the following places: within a NOTICE text file distributed
         as part of the Derivative Works; within the Source form or
         documentation, if provided along with the Derivative Works; or,
         within a display generated by the Derivative Works, if and
         wherever such third-party notices normally appear. The contents
         of the NOTICE file are for informational purposes only and
         do not modify the License. You may add Your own attribution
         notices within Derivative Works that You distribute, alongside
         or as an addendum to the NOTICE text from the Work, provided
         that such additional attribution notices cannot be construed
         as modifying the License.

     You may add Your own copyright statement to Your modifications and
     may provide additional or different license terms and conditions
     for use, reproduction, or distribution of Your modifications, or
     for any such Derivative Works as a whole, provided Your use,
     reproduction, and distribution of the Work otherwise complies with
     the conditions stated in this License.

  5. Submission of Contributions. Unless You explicitly state otherwise,
     any Contribution intentionally submitted for inclusion in the Work
     by You to the Licensor shall be under the terms and conditions of
     this License, without any additional terms or conditions.
     Notwithstanding the above, nothing herein shall supersede or modify
     the terms of any separate license agreement you may have executed
     with Licensor regarding such Contributions.

  6. Trademarks. This License does not grant permission to use the trade
     names, trademarks, service marks, or product names of the Licensor,
     except as required for reasonable and customary use in describing the
     origin of the Work and reproducing the content of the NOTICE file.

  7. Disclaimer of Warranty. Unless required by applicable law or
     agreed to in writing, Licensor provides the Work (and each
     Contributor provides its Contributions) on an "AS IS" BASIS,
     WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
     implied, including, without limitation, any warranties or conditions
     of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
     PARTICULAR PURPOSE. You are solely responsible for determining the
     appropriateness of using or redistributing the Work and assume any
     risks associated with Your exercise of permissions under this License.

  8. Limitation of Liability. In no event and under no legal theory,
     whether in tort (including negligence), contract, or otherwise,
     unless required by applicable law (such as deliberate and grossly
     negligent acts) or agreed to in writing, shall any Contributor be
     liable to You for damages, including any direct, indirect, special,
     incidental, or consequential damages of any character arising as a
     result of this License or out of the use or inability to use the
     Work (including but not limited to damages for loss of goodwill,
     work stoppage, computer failure or malfunction, or any and all
     other commercial damages or losses), even if such Contributor
     has been advised of the possibility of such damages.

  9. Accepting Warranty or Additional Liability. While redistributing
     the Work or Derivative Works thereof, You may choose to offer,
     and charge a fee for, acceptance of support, warranty, indemnity,
     or other liability obligations and/or rights consistent with this
     License. However, in accepting such obligations, You may act only
     on Your own behalf and on Your sole responsibility, not on behalf
     of any other Contributor, and only if You agree to indemnify,
     defend, and hold each Contributor harmless for any liability
     incurred by, or claims asserted against, such Contributor by reason
     of your accepting any such warranty or additional liability.

             The "Artistic License"

                Preamble

The intent of this document is to state the conditions under which a
Package may be copied, such that the Copyright Holder maintains some
semblance of artistic control over the development of the package,
while giving the users of the package the right to use and distribute
the Package in a more-or-less customary fashion, plus the right to make
reasonable modifications.

Definitions:

    "Package" refers to the collection of files distributed by the
    Copyright Holder, and derivatives of that collection of files
    created through textual modification.

    "Standard Version" refers to such a Package if it has not been
    modified, or has been modified in accordance with the wishes
    of the Copyright Holder as specified below.

    "Copyright Holder" is whoever is named in the copyright or
    copyrights for the package.

    "You" is you, if you're thinking about copying or distributing
    this Package.

    "Reasonable copying fee" is whatever you can justify on the
    basis of media cost, duplication charges, time of people involved,
    and so on.  (You will not be required to justify it to the
    Copyright Holder, but only to the computing community at large
    as a market that must bear the fee.)

    "Freely Available" means that no fee is charged for the item
    itself, though there may be fees involved in handling the item.
    It also means that recipients of the item may redistribute it
    under the same conditions they received it.

1. You may make and give away verbatim copies of the source form of the
Standard Version of this Package without restriction, provided that you
duplicate all of the original copyright notices and associated disclaimers.

2. You may apply bug fixes, portability fixes and other modifications
derived from the Public Domain or from the Copyright Holder.  A Package
modified in such a way shall still be considered the Standard Version.

3. You may otherwise modify your copy of this Package in any way, provided
that you insert a prominent notice in each changed file stating how and
when you changed that file, and provided that you do at least ONE of the
following:

    a) place your modifications in the Public Domain or otherwise make them
    Freely Available, such as by posting said modifications to Usenet or
    an equivalent medium, or placing the modifications on a major archive
    site such as uunet.uu.net, or by allowing the Copyright Holder to include
    your modifications in the Standard Version of the Package.

    b) use the modified Package only within your corporation or organization.

    c) rename any non-standard executables so the names do not conflict
    with standard executables, which must also be provided, and provide
    a separate manual page for each non-standard executable that clearly
    documents how it differs from the Standard Version.

    d) make other distribution arrangements with the Copyright Holder.

4. You may distribute the programs of this Package in object code or
executable form, provided that you do at least ONE of the following:

    a) distribute a Standard Version of the executables and library files,
    together with instructions (in the manual page or equivalent) on where
    to get the Standard Version.

    b) accompany the distribution with the machine-readable source of
    the Package with your modifications.

    c) give non-standard executables non-standard names, and clearly
    document the differences in manual pages (or equivalent), together
    with instructions on where to get the Standard Version.

    d) make other distribution arrangements with the Copyright Holder.

5. You may charge a reasonable copying fee for any distribution of this
Package.  You may charge any fee you choose for support of this
Package.  You may not charge a fee for this Package itself.  However,
you may distribute this Package in aggregate with other (possibly
commercial) programs as part of a larger (possibly commercial) software
distribution provided that you do not advertise this Package as a
product of your own.  You may embed this Package's interpreter within
an executable of yours (by linking); this shall be construed as a mere
form of aggregation, provided that the complete Standard Version of the
interpreter is so embedded.

6. The scripts and library files supplied as input to or produced as
output from the programs of this Package do not automatically fall
under the copyright of this Package, but belong to whoever generated
them, and may be sold commercially, and may be aggregated with this
Package.  If such scripts or library files are aggregated with this
Package via the so-called "undump" or "unexec" methods of producing a
binary executable image, then distribution of such an image shall
neither be construed as a distribution of this Package nor shall it
fall under the restrictions of Paragraphs 3 and 4, provided that you do
not represent such an executable image as a Standard Version of this
Package.

7. C subroutines (or comparably compiled subroutines in other
languages) supplied by you and linked into this Package in order to
emulate subroutines and variables of the language defined by this
Package shall not be considered part of this Package, but are the
equivalent of input as in Paragraph 6, provided these subroutines do
not change the language in any way that would cause it to fail the
regression tests for the language.

8. Aggregation of this Package with a commercial distribution is always
permitted provided that the use of this Package is embedded; that is,
when no overt attempt is made to make this Package's interfaces visible
to the end user of the commercial distribution.  Such use shall not be
construed as a distribution of this Package.

9. The name of the Copyright Holder may not be used to endorse or promote
products derived from this software without specific prior written permission.

10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

provided that such additional attribution notices cannot be construed as
modifying the License.

     You may add Your own copyright statement to Your modifications and may
provide additional or different license terms and conditions for use,
reproduction, or distribution of Your modifications, or for any such Derivative
Works as a whole, provided Your use, reproduction, and distribution of the Work
otherwise complies with the conditions stated in this License.

writing, shall any Contributor be liable to You for damages, including any
direct, indirect, special, incidental, or consequential damages of any character
arising as a result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill, work stoppage,
computer failure or malfunction, or any and all other commercial damages or
losses), even if such Contributor has been advised of the possibility of such
damages.

9. Accepting Warranty or Additional Liability. While redistributing the Work or
Derivative Works thereof, You may choose to offer, and charge a fee for,
acceptance of support, warranty, indemnity, or other liability obligations
and/or rights consistent with this License. However, in accepting such
obligations, You may act only on Your own behalf and on Your sole
responsibility, not on behalf of any other Contributor, and only if You agree to
indemnify, defend, and hold each Contributor harmless for any liability incurred
by, or claims asserted against, such Contributor by reason of your accepting any
such warranty or additional liability.

# LibWebsockets
```

** libwebsockets; version 4.3 -- https://github.com/warmcat/libwebsockets
(C) Copyright 2010-2011 Andy Green <andy@warmcat.com> licensed under MIT
 
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
  - win32port/zlib            - ZLIB license (see zlib.h)
  - lib/tls/mbedtls/wrapper   - Apache 2.0 (only built if linked against
mbedtls)
  - lib/misc/base64-decode.c  - already MIT

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.
