       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

       1. Definitions.

          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.

          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.

          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,
          "control" means (i) the power, direct or indirect, to cause the
          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.

          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.

          "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
          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
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          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.

      license document; it basically says:

        License 1 — License for Open-Source Software Implementations of OCB
                    (Jan 9, 2013)

        Under this license, you are authorized to make, use, and
        distribute open-source software implementations of OCB. This
        license terminates for you if you sue someone over their
        open-source software implementation of OCB claiming that you have
        a patent covering their implementation.

     License for Open Source Software Implementations of OCB
     January 9, 2013

     1 Definitions

     1.1 “Licensor” means Phillip Rogaway.

     1.2 “Licensed Patents” means any patent that claims priority to United
     States Patent Application No. 09/918,615 entitled “Method and Apparatus
     for Facilitating Efficient Authenticated Encryption,” and any utility,
     divisional, provisional, continuation, continuations-in-part, reexamination,
     reissue, or foreign counterpart patents that may issue with respect to the
     aforesaid patent application. This includes, but is not limited to, United
     States Patent No. 7,046,802; United States Patent No. 7,200,227; United
     States Patent No. 7,949,129; United States Patent No. 8,321,675 ; and any
     patent that issues out of United States Patent Application No. 13/669,114.

     1.3 “Use” means any practice of any invention claimed in the Licensed Patents.

     1.4 “Software Implementation” means any practice of any invention
     claimed in the Licensed Patents that takes the form of software executing on
     a user-programmable, general-purpose computer or that takes the form of a
     computer-readable medium storing such software. Software Implementation does
     not include, for example, application-specific integrated circuits (ASICs),
     field-programmable gate arrays (FPGAs), embedded systems, or IP cores.

     1.5 “Open Source Software” means software whose source code is published
     and made available for inspection and use by anyone because either (a) the
     source code is subject to a license that permits recipients to copy, modify,
     and distribute the source code without payment of fees or royalties, or
     (b) the source code is in the public domain, including code released for
     public use through a CC0 waiver. All licenses certified by the Open Source
     Initiative at opensource.org as of January 9, 2013 and all Creative Commons
     licenses identified on the creativecommons.org website as of January 9,
     2013, including the Public License Fallback of the CC0 waiver, satisfy these
     requirements for the purposes of this license.

     1.6 “Open Source Software Implementation” means a Software
     Implementation in which the software implicating the Licensed Patents is
     Open Source Software. Open Source Software Implementation does not include
     any Software Implementation in which the software implicating the Licensed
     Patents is combined, so as to form a larger program, with software that is
     not Open Source Software.

     2 License Grant

     2.1 License. Subject to your compliance with the term s of this license,
     including the restriction set forth in Section 2.2, Licensor hereby
     grants to you a perpetual, worldwide, non-exclusive, non-transferable,
     non-sublicenseable, no-charge, royalty-free, irrevocable license to practice
     any invention claimed in the Licensed Patents in any Open Source Software
     Implementation.

     2.2 Restriction. If you or your affiliates institute patent litigation
     (including, but not limited to, a cross-claim or counterclaim in a lawsuit)
     against any entity alleging that any Use authorized by this license
     infringes another patent, then any rights granted to you under this license
     automatically terminate as of the date such litigation is filed.

     3 Disclaimer
     YOUR USE OF THE LICENSED PATENTS IS AT YOUR OWN RISK AND UNLESS REQUIRED
     BY APPLICABLE LAW, LICENSOR MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
     KIND CONCERNING THE LICENSED PATENTS OR ANY PRODUCT EMBODYING ANY LICENSED
     PATENT, EXPRESS OR IMPLIED, STATUT ORY OR OTHERWISE, INCLUDING, WITHOUT
     LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A PARTICULAR
     PURPOSE, OR NONINFRINGEMENT. IN NO EVENT WILL LICENSOR BE LIABLE FOR ANY
     CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN CONTRACT, TORT OR OTHERWISE,
     ARISING FROM OR RELATED TO ANY USE OF THE LICENSED PATENTS, INCLUDING,
     WITHOUT LIMITATION, DIRECT, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE
     OR SPECIAL DAMAGES, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF
     SUCH DAMAGES PRIOR TO SUCH AN OCCURRENCE.
