+GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    {one line to give the program's name and a brief idea of what it does.}
+    Copyright (C) 2017  {name of author}
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    navicat-keygen  Copyright (C) 2017  Double Helix
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+# Navicat Keygen
+
+[中文版README](README.zh-CN.md)
+
+This repository will tell you how Navicat offline activation works.
+
+Previous code is archived in [`windows-archived`](https://github.com/DoubleLabyrinth/navicat-keygen/tree/windows-archived) branch for the reason that previos code contains 3rd binary libraries and it gets quite big :-(.
+
+When you git-clone this repo, please add `--single-branch` flag so that archived branch won't be cloned to your computer, which saves your time and disk.
+
+```console
+$ git clone -b windows --single-branch https://github.com/DoubleLabyrinth/navicat-keygen.git
+```
+
+## 1. How does it work?

+# Navicat Keygen
+
+这份repo将会告诉你Navicat是怎么完成离线激活的。
+
+由于历史代码包含第三方二进制库,且大小较大,故决定将该项目的历史代码归档到 [`windows-archived`](https://github.com/DoubleLabyrinth/navicat-keygen/tree/windows-archived) 分支。
+
+当你clone该仓库的时候,请使用 `--single-branch` 选项,以此避免clone到 `windows-archived` 分支,并且还可以节省你的时间和磁盘空间。
+
+```console
+$ git clone -b windows --single-branch https://github.com/DoubleLabyrinth/navicat-keygen.git
+```
+
+## 1. 注册机是怎么工作的?

+
+## 2. 如何编译?
+
+见[这里](doc/how-to-build.zh-CN.md)。
+
+## 3. 如何使用这个注册机?

+
+## 1. Keyword Explanation.
+
+* __Navicat Activation Public Key__
+
+  It is a __RSA-2048__ public key that Navicat used to encrypt or decrypt offline activation information.
+
+  It is stored in __navicat.exe__ as a kind of resource called __RCData__. The resource name is `"ACTIVATIONPUBKEY"`. You can see it by a software called [___Resource Hacker___](http://www.angusj.com/resourcehacker/). The public key is

+
+  If you have the corresponding private key, you can tell me. I would be very appreciated for your generous.
+
+  __NOTICE:__
+
+  Start from __Navicat Premium 12.0.25__, Navicat do not load this public key from resource in `navicat.exe`. Instead, the public key is stored in `libcc.dll` and has been encrypted. To avoid being replaced easily, the public key is split into 5 parts:
+
+  The following content is discovered from `libcc.dll` of __Navicat Premium x64 12.0.25 Simplified Chinese version__. The SHA256 value of `libcc.dll` is `607e0a84c75966b00f3d12fa833e91d159e4f51ac51b6ba66f98d0c3cbefdce0`. 
+  
+  I __DO NOT__ guarantee that offset values are absolutely correct in other versions. But __char strings__ and __immediate values__ are highly possible to be found.

+  ```
+
+  __NOTICE:__
+
+  Start from __Navicat Premium 12.1.11__, Navicat do not load the public key through the method I talked before. Of course, the public key is still stored in `libcc.dll`. When Navicat starts, it encrypts the public key by an 8-bytes-long XOR key and stores the ciphertext in static area. When verifing __Activation Code__, Navicat will regenerate the 8-bytes-long XOR key and decrypts the ciphertext in static area to get the public key.
+
+  In `libcc.dll`, x64 version, you can find some instructions that looks like:
+
+  ```asm
+  xor eax, 'M'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'I'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'I'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'B'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'I'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'j'
+  mov byte_xxxxxx, al
+  ...
+  ...
+  ```
+
+* __Request Code__
+
+  It is a Base64 string that represents 256-bytes-long data, while the 256-bytes-long data is the cipher text of __Offline Activation Request Information__ encrypted by __Navicat Activation Public Key__.
+
+* __Offline Activation Request Information__
+
+  It is just a JSON-style ASCII string which contains 3 items. They are `"K"`, `"DI"` and `"P"` respectively, which represent __snKey__, __DeviceIdentifier__ (related with your machine), __Platform__ (OS Type).
+
+  Like
+
+  ```  
+  {"K": "xxxxxxxxxxxxxxxx", "DI": "yyyyyyyyyyyyy", "P": "WIN8"}
+  ```
+
+* __Activation Code__
+
+  It is a Base64 string that represents 256-bytes-long data, while the 256-bytes-long data is the cipher text of the __Offline Activation Response Information__ encrypted by __Navicat Activation Private Key__. So far, we don't know the official activation private key and we have to replace it in `navicat.exe` and `libcc.dll`.
+
+* __Offline Activation Response Information__
+
+  Just like __Offline Activation Request Information__, it is also a JSON-style ASCII string. But it contains 5 items. They are `"K"`, `"N"`, `"O"`, `"T"` and `"DI"` respectively.
+
+  `"K"` and `"DI"` has the same meaning that is mentioned in __Offline Activation Request Information__ and must be the same with the corresponding items in __Offline Activation Request Information__.
+
+  `"N"`, `"O"`, `"T"` represent __Name__, __Organization__, __Timestamp__ respectively. __Name__ and __Organization__ are UTF-8 strings and the type of __Timestamp__ can be string or integer. (Thanks for discoveries from @Wizr, issue #10)
+
+  `"T"` can be omitted.
+
+* __snKey__
+
+  It is a 4-block-long string, while every block is 4-chars-long.
+
+  __snKey__ is generated by 10-bytes-long data. In order to explain it easily, I use __uint8_t data[10]__ to represent the 10-bytes-long data.
+
+  1. __data[0]__ and __data[1]__ must be `0x68` and `0x2A` respectively.
+
+     These two bytes are Naivcat signature number.
+
+  2. __data[2]__, __data[3]__ and __data[4]__ can be any byte. Just set them whatever you want.
+
+  3. __data[5]__ and __data[6]__ are product language signatures.

+
+  5. High 4 bits of __data[8]__ represents __major version number__. 
+   
+     Low 4 bits is unknown, but we can use it to delay activation deadline. Possible values are `0000` or `0001`.
+
+     __Example:__
+
+     For __Navicat 12 x64__: High 4 bits must be `1100`, which is the binary of number `12`.  
+     For __Navicat 11 x64__: High 4 bits must be `1011`, which is the binary of number `11`.  
+
+  6. __data[9]__ is unknown, but you can set it by `0xFD`, `0xFC` or `0xFB` if you want to use __not-for-resale license__.
+
+     According to symbol information in __Navicat 12 for Mac x64__ version:
+
+     * `0xFB` is __Not-For-Resale-30-days__ license.  
+     * `0xFC` is __Not-For-Resale-90-days__ license.  
+     * `0xFD` is __Not-For-Resale-365-days__ license.  
+     * `0xFE` is __Not-For-Resale__ license.  
+     * `0xFF` is __Site__ license.  
+
+  After `uint8_t data[10]` is ready, Navicat uses __DES__ with __ECB mode__ to encrypt the last 8 bytes of `uint8_t data[10]` which are from __data[2]__ to __data[9]__.
+
+  The DES key is:
+
+  ```cpp
+  unsigned char DESKey = { 0x64, 0xAD, 0xF3, 0x2F, 0xAE, 0xF2, 0x1A, 0x27 };
+  ```
+
+  Then use Base32 to encode `uint8_t data[10]` whose encode table is
+
+  ```cpp
+  char EncodeTable[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ234567";
+  ```
+
+  After encoding, you will get a 16-char-long string starting with `"NAV"`.
+
+  Finally, divide the 16-char-long string to four 4-chars-long blocks and join them with `"-"` then you will get __snKey__.
+
+## 2. Activation Process
+
+1. Check whether __snKey__ that user inputs is valid.
+
+2. After user clicks `Activate`, Navicat will start online activation first. If fails, user can choose offline activation.
+
+3. Navicat will use the __snKey__ that user inputs and some information collected from user's machine to generate __Offline Activation Request Information__. Then Navicat will encrypt it by __Navicat Activation Public Key__ and return a Base64-encoded string as __Request Code__.
+
+4. In legal way, the __Request Code__ should be sent to Navicat official activation server by a Internet-accessible computer. And Navicat official activation server will return a legal __Activation Code__.
+
+   But now, we use keygen to play the official activation server's role.
+
+   1. According to the __Request Code__, get `"DI"` value and `"K"` value.
+
+   2. Fill __Offline Activation Response Information__ with `"K"` value, name, organization name, `"DI"` value and, if need, `"T"` value. 
+
+   3. Encrypt __Offline Activation Response Information__ by __Navicat Activation Private Key__ and you will get 256-byte-long data.
+

+* __Navicat激活公钥__
+
+  这是一个2048位的RSA公钥,Navicat使用这个公钥来完成相关激活信息的加密和解密。
+
+  这个公钥被作为 __RCData__ 类型的资源储存在 __navicat.exe__ 当中。资源名为`"ACTIVATIONPUBKEY"`。你可以使用一个叫[Resource Hacker](http://www.angusj.com/resourcehacker/)的软件来查看它。这个公钥的具体内容为:

+  如果您有相应的私钥并乐意公开的话欢迎联系我,我将非常感谢您的慷慨。
+
+  __注意:__
+
+  从 __Navicat Premium 12.0.25__ 开始,Navicat不再从`navicat.exe`的资源中加载私钥。事实上,公钥转为从`libcc.dll`中加载,并且已经被加密。与此同时,为了防止被轻松地替换,加密的公钥被分到5个地方储存:
+
+  以下内容是从 __Navicat Premium x64 12.0.25 简体中文版__ 的`libcc.dll`中发现的,`libcc.dll`的SHA256值为`607e0a84c75966b00f3d12fa833e91d159e4f51ac51b6ba66f98d0c3cbefdce0`。我不保证在Navicat的其他版本中相关偏移量和下述的相同,但相关的 __字符串__ 以及 __立即数__ 是很可能找得到的。
+
+  1. 在`libcc.dll`中,文件偏移量`+0x01A12090`的地方,储存了加密公钥的第一部分,以 __字符串__ 的形式储存:  
+
+     ```

+     ```
+
+  2. 在`libcc.dll`中,文件偏移量`+0x0059D799`的地方,储存了加密公钥的第二部分,以 __立即数__ 的形式储存在一条指令中:

+      449B4E"
+     ```
+
+  4. 在`libcc.dll`中,文件偏移量`+0x0059D77F`的地方,储存了加密公钥的第四部分,以 __立即数__ 的形式储存在一条指令中:
+
+      ```
+      0x59 0x08 0x01 0x00

+
+      ```
+      "92933"
+      ```
+
+  这五部分按照`"%s%d%s%d%s"`的形式输出则为加密的公钥,顺序和上述的顺序相同,具体的输出为:

+
+  __注意:__
+
+  从 __Navicat Premium 12.1.11__ 开始,Navicat不再用上面说的方法加载密钥。当然密钥还是储存在`libcc.dll`文件中。当Navicat启动时,它会用8字节长的XOR密钥来加密公钥,并储存到一个静态数据区中。当验证 __激活码__ 时,Navicat会重新生成一样的8字节XOR密钥,并解密在静态储存区中的密文,从而获取公钥。
+
+  在`libcc.dll`,x64版本中,你会看到如下的几条指令:
+
+  ```asm
+  xor eax, 'M'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'I'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'I'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'B'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'I'
+  mov byte_xxxxxx, al
+  ...
+  xor eax, 'j'
+  mov byte_xxxxxx, al
+  ...
+  ...
+  ```
+
+* __请求码__
+
+  这是一个Base64编码的字符串,代表的是长度为256字节的数据。这256字节的数据是 __离线激活信息__ 用 __Navicat激活公钥__ 加密的密文。
+
+* __离线激活请求信息__
+
+  这是一个JSON风格的字符串。它包含了3个Key:`"K"`、`"DI"`和`"P"`,分别代表 __序列号__、__设备识别码__(与你的电脑硬件信息相关)和 __平台__ (其实就是操作系统类型)。
+
+  例如:  
+
+  ```  
+  {"K": "xxxxxxxxxxxxxxxx", "DI": "yyyyyyyyyyyyy", "P": "WIN8"}
+  ```
+
+* __激活码__
+
+  这是一个Base64编码的字符串,代表的是长度为256字节的数据。这256字节的数据是 __离线激活回复信息__ 用 __Navicat激活私钥__ 加密的密文。目前我们不知道官方的 __Navicat激活私钥__,所以我们得替换掉软件里的公钥。
+
+* __离线激活回复信息__
+
+  和 __离线激活请求信息__ 一样,它也是一个JSON风格的字符串。但是它包含5个Key,分别为`"K"`、`"N"`、`"O"`、`"T"` 和 `"DI"`.
+
+  `"K"` 和 `"DI"` 的意义与 __离线激活请求信息__ 中的相同,且Value必须与 __离线激活请求信息__ 中的相同。
+
+  `"N"`、`"O"`、`"T"` 分别代表 __注册名__、__组织__、__授权时间__。
+  
+  __注册名__ 和 __组织__ 的值类型为UTF-8编码的字符串。__授权时间__ 的值类型可以为字符串或整数(感谢@Wizr在issue #10中的报告)。
+
+    `"T"` 可以被省略。
+
+* __序列号__
+
+  这是一个被分为了4个部分的字符串,其中每个部分都是4个字符长。
+
+  __序列号__ 是通过10个字节的数据来生成的。为了表达方便,我用 __uint8_t data[10]__ 来表示这10个字节。
+
+  1. __data[0]__ 和 __data[1]__ 必须分别为 `0x68` 和 `0x2A`。
+
+     这两个字节为Navicat的标志数。
+
+  2. __data[2]__、__data[3]__ 和 __data[4]__ 可以是任意字节,你想设成什么都行。
+
+  3. __data[5]__ 和 __data[6]__ 是Navicat的语言标志,值如下:
+
+     |  语言类型   |  data[5]  |  data[6]  |  发现者         |

+     |Navicat MongoDB      |0x80      |0x81    |0x82       |          |
+
+  5. __data[8]__ 的高4位代表 __版本号__。低4位未知,但可以用来延长激活期限,可取的值有`0000`和`0001`。
+
+     例如:
+
+     对于 __Navicat 12__: 高4位必须是`1100`,为`12`的二进制形式。  
+     对于 __Navicat 11__: 高4位必须是`1011`,为`11`的二进制形式。  
+
+  6. __data[9]__ 目前暂未知,但如果你想要 __not-for-resale license__ 的话可以设成`0xFD`、`0xFC`或`0xFB`。
+
+     根据 __Navicat 12 for Mac x64__ 版本残留的符号信息可知:
+
+     * `0xFB`是 __Not-For-Resale-30-days__ license.  
+     * `0xFC`是 __Not-For-Resale-90-days__ license.  
+     * `0xFD`是 __Not-For-Resale-365-days__ license.  
+     * `0xFE`是 __Not-For-Resale__ license.  
+     * `0xFF`是 __Site__ license.  
+
+  之后Navicat使用 __ECB__ 模式的 __DES__ 算法来加密 __data[10]__ 的后8字节,也就是 __data[2]__ 到 __data[9]__ 的部分。
+
+  相应的DES密钥为:
+
+  ```cpp
+  unsigned char DESKey = { 0x64, 0xAD, 0xF3, 0x2F, 0xAE, 0xF2, 0x1A, 0x27 };
+  ```
+
+  之后使用Base32编码 __data[10]__,其中编码表改为:
+
+  ```cpp
+  char EncodeTable[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ234567";
+  ```
+
+  编码之后你应该会得到一个16字节长的字符串,并且以"NAV"打头。
+
+  将16字节的字符串分成4个4字节的小块,然后用`"-"`连接就可以得到 __序列号__。
+
+## 2. 激活过程
+
+  1. 检查用户输入的 __序列号__ 是否合法。
+
+  2. 在用户点击了`激活`按钮之后,Navicat会先尝试在线激活。如果失败,用户可以选择离线激活。
+
+  3. Navicat会使用用户输入的 __序列号__ 以及从用户电脑收集来的信息生成 __离线激活请求信息__,然后用 __Navicat激活公钥__ 加密,并将密文用Base64编码,最后得到 __请求码__。
+
+  4. 正常流程下,__请求码__ 应该通过可联网的电脑发送给Navicat的官方激活服务器。之后Navicat的官方激活服务器会返回一个合法的 __激活码__。
+
+     但现在我们使用注册机来扮演官方激活服务器的角色,只是Navicat软件里的激活公钥得换成自己的公钥:
+
+     1. 根据 __请求码__, 获得`"DI"`值和`"K"`值。
+
+     2. 用`"K"`值、用户名、组织名和`"DI"`值填写 __离线激活回复信息__。
+
+     3. 用自己的2048位RSA私钥加密 __离线激活回复信息__,你将会得到256字节的密文。
+
+     4. 用Base64编码这256字节的密文,就可以得到 __激活码__。
+
+     5. 在Navicat软件中填入 __激活码__ 即可完成离线激活。

+
+* Maintainer(s): zenuo, DoubleLabyrinth
+
+---
+
+> You can download [Screen recoding](image/Screen_recording.mp4) for references.
+
+1. Switch to the path you extracted the installation package. Run Navicat, for initialization:
+
+   ```console
+   $ cd ~/navicat121_premium_en_x64 && \
+   ./start_navicat
+   ```
+
+   When running for the first time, you will be prompted with the following two windows, click "Cancel" to:

+
+   ![](image/Screenshot_2019-04-30_12-31-52.png)
+
+   Until the `Registration` window appears, select `Trial`, close Navicat after loading is complete, and execute `Step 2`:
+
+   ![](image/Screenshot_2019-04-30_12-32-43.png)
+
+2. Download the latest release [from here](https://github.com/DoubleLabyrinth/navicat-keygen/releases), and extract:
+
+   > The 64-bit executable file is downloaded here. If you use 32-bit, please download the corresponding version.
+
+   ```console
+   $ curl -O -L https://github.com/DoubleLabyrinth/navicat-keygen/releases/download/v3.1/navicat-keygen-for-x64.zip && \
+   unzip navicat-keygen-for-x64.zip
+   ```
+
+3. Download `navicat-pacther.sh` and `navicat-keygen.sh`:
+
+   ```console
+   $ curl -O -L https://raw.githubusercontent.com/DoubleLabyrinth/navicat-keygen/windows/bash/navicat-patcher.sh && \
+   chmod +x navicat-patcher.sh && \
+   curl -O -L https://raw.githubusercontent.com/DoubleLabyrinth/navicat-keygen/windows/bash/navicat-keygen.sh && \
+   chmod +x navicat-keygen.sh
+   ```
+
+4. Use `navicat-patcher.exe` to replace __Navicat Activation Public Key__ that is stored in `navicat.exe` or `libcc.dll`.
+
+   > Please turn off `Navicat` when performing this step.
+
+   ```console
+   $ ./navicat-patcher.sh
+   ```
+
+   It has been tested on __Navicat Premium 12.1.22 Simplified Chinese version__. The following is an example of output:

+
+5. Then use `navicat-keygen.exe` to generate __snKey__ and __Activation Code__
+
+   ```console
+   $ ./navicat-keygen.sh
+   ```
+
+   You will be asked to select Navicat product, language and input major version number. After that an randomly generated __snKey__ will be given.
+
+   ```
+   Select Navicat product:
+   0. DataModeler
+   1. Premium
+   2. MySQL
+   3. PostgreSQL
+   4. Oracle
+   5. SQLServer
+   6. SQLite
+   7. MariaDB
+   8. MongoDB
+   9. ReportViewer
+
+   (Input index)> 1
+
+   Select product language:
+   0. English
+   1. Simplified Chinese
+   2. Traditional Chinese
+   3. Japanese
+   4. Polish
+   5. Spanish
+   6. French
+   7. German
+   8. Korean
+   9. Russian
+   10. Portuguese

+   (Input index)> 1
+
+   (Input major version number, range: 0 ~ 15, default: 12)> 12
+
+   Serial number:
+   NAVO-2ORP-IN5A-GQEE
+
+   Your name: 
+   ```
+
+   You can use this __snKey__ to activate your Navicat preliminarily.
+     
+   Then you will be asked to input `Your name` and `Your organization`. Just set them whatever you want, but not too long.
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+   Input request code (in Base64), input empty line to end:
+   ```
+     
+   After that, you will be asked to input the request code. Now __DO NOT CLOSE KEYGEN__.
+
+6. __Set up__ a invalid proxy. Find and click `Registration`. Fill `Registration Key` by __snKey__ that the keygen gave and click `Activate`.
+
+7. Online activation will failed and Navicat will ask you do `Manual Activation`, just choose it.
+
+8. Copy your request code and paste it in the keygen. Input empty line to tell the keygen that your input ends.
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+
+   Input request code (in Base64), input empty line to end:

+   ```
+
+9. Finally, you will get __Activation Code__ which looks like a Base64 string. Just copy it and paste it in Navicat `Manual Activation` window, then click `Activate`. If nothing wrong, activation should be done successfully. Don't forget to close the proxy that we just set up.

+
+> 可下载[录屏文件](image/Screen_recording.mp4)参考
+
+1. 切换到解压安装包的路径,本示例解压到了 `家目录`,运行Navicat,使其初始化环境:
+
+    ```console
+    $ cd ~/navicat121_premium_en_x64 && \
+    ./start_navicat
+    ```
+
+    首次启动时,会提示如下两个窗口,点击“Cancel”即可:

+
+    ![](image/Screenshot_2019-04-30_12-31-52.png)
+
+    直至出现 `Registration` 窗口,选择 `Trial`,待加载完成后关闭Navicat,执行 `步骤2`:

+    ![](image/Screenshot_2019-04-30_12-32-43.png)
+
+2. [从这里](https://github.com/DoubleLabyrinth/navicat-keygen/releases)下载最新的release,并且解压:
+
+    > 此处下载的是64位的可执行文件,若您使用32位,请下载对应版本
+

+    unzip navicat-keygen-for-x64.zip
+    ```
+
+3. 下载 `navicat-pacther.sh` 和 `navicat-keygen.sh`:
+
+    ```console
+    $ curl -O -L https://raw.githubusercontent.com/DoubleLabyrinth/navicat-keygen/windows/bash/navicat-patcher.sh && \

+    chmod +x navicat-keygen.sh
+    ```
+
+4. 使用 `navicat-patcher.exe` 替换掉 `navicat.exe` 和 `libcc.dll` 里的Navicat激活公钥。 
+
+   > 执行此步骤时,请将Navicat关闭

+
+5. 接下来使用`navicat-keygen.exe`来生成序列号和激活码
+
+   ```console
+   $ ./navicat-keygen.sh
+   ```
+
+   你会被要求选择Navicat产品类别、语言以及输入主版本号。之后会随机生成一个序列号。
+
+   ```
+   Select Navicat product:
+   0. DataModeler
+   1. Premium
+   2. MySQL
+   3. PostgreSQL
+   4. Oracle
+   5. SQLServer
+   6. SQLite
+   7. MariaDB
+   8. MongoDB
+   9. ReportViewer
+
+   (Input index)> 1
+
+   Select product language:
+   0. English
+   1. Simplified Chinese
+   2. Traditional Chinese
+   3. Japanese
+   4. Polish
+   5. Spanish
+   6. French
+   7. German
+   8. Korean
+   9. Russian
+   10. Portuguese
+
+   (Input index)> 1
+
+   (Input major version number, range: 0 ~ 15, default: 12)> 12
+
+   Serial number:
+   NAVO-2ORP-IN5A-GQEE
+
+   Your name: 
+   ```
+
+   你可以使用这个序列号暂时激活Navicat。
+
+   接下来你会被要求输入`用户名`和`组织名`;请随便填写,但不要太长。
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+   Input request code (in Base64), input empty line to end:
+   ```
+ 
+   之后你会被要求填入请求码。注意 __不要关闭命令行__.
+
+6. 配置一个不存在的`代理`。找到`注册`窗口,并填入keygen给你的序列号。然后点击`激活`按钮。
+
+7. 在线激活失败,这时候Navicat会询问你是否`手动激活`,直接选吧。
+
+8. 在`手动激活`窗口你会得到一个请求码,复制它并把它粘贴到keygen里。最后别忘了连按至少两下回车结束输入。
+
+   ```

+
+9. 如果不出意外,你会得到一个看似用Base64编码的激活码。直接复制它,并把它粘贴到Navicat的`手动激活`窗口,最后点`激活`按钮。如果没什么意外的话应该能成功激活。别忘了关闭我们刚刚设置的不存在的代理哦。

+# Navicat Keygen - How to use? (Windows)
+
+[中文版](how-to-use.windows.zh-CN.md)
+
+1. Download the latest release [from here](https://github.com/DoubleLabyrinth/navicat-keygen/releases).
+
+2. Use `navicat-patcher.exe` to replace __Navicat Activation Public Key__ that is stored in `navicat.exe` or `libcc.dll`.
+   
+   ```
+   navicat-patcher.exe [-dry-run] <Navicat Installation Path> [RSA-2048 PEM File Path]
+   ```
+
+   * `[-dry-run]` Run patcher without applying any patches.
+
+     __This parameter is optional.__ 
+
+   * `<Navicat Installation Path>`: The full path to Navicat installation folder. 
+     
+     __This parameter must be specified.__
+
+   * `[RSA-2048 PEM File Path]`: The full path or relative path to a RSA-2048 private key file. 
+     
+     __This parameter is optional.__ If not specified, `navicat-patcher.exe` will generate a new RSA-2048 private key file `RegPrivateKey.pem` at current directory.
+
+   __Example: (in cmd.exe)__ 
+
+   ```
+   navicat-patcher.exe "C:\Program Files\PremiumSoft\Navicat Premium 12"
+   ```
+   
+   It has been tested on __Navicat Premium 12.1.22 Simplified Chinese version__. The following is an example of output.
+
+   ```

+
+     If `-text` is specified, `navicat-keygen.exe` will finally generate a Base64-style string which is __Activation Code__. It is used for Navicat new activation method. 
+
+     __This parameter must be specified.__
+
+   * `[-adv]`: Enable advanced mode.
+
+     __This parameter is optional.__ If specified, `navicat-keygen.exe` will ask you input Navicat product ID number, language signature numbers. It is for future use generally.

+
+   You will be asked to select Navicat product, language and input major version number. After that an randomly generated __snKey__ will be given.

+
+   You can use this __snKey__ to activate your Navicat preliminarily.
+     
+   Then you will be asked to input `Your name` and `Your organization`. Just set them whatever you want, but not too long.
+
+   ```
+   Your name: DoubleLabyrinth
+   Your organization: DoubleLabyrinth
+   Input request code (in Base64), input empty line to end:
+   ```
+     
+   After that, you will be asked to input the request code. Now __DO NOT CLOSE KEYGEN__.
+
+4. __Disconnect your network__ and open Navicat. Find and click `Registration`. Fill `Registration Key` by __snKey__ that the keygen gave and click `Activate`.
+
+5. Generally online activation will failed and Navicat will ask you do `Manual Activation`, just choose it.
+
+6. Copy your request code and paste it in the keygen. Input empty line to tell the keygen that your input ends.

+# Navicat Keygen - 如何使用这个注册机? (Windows)
+
+1. [从这里](https://github.com/DoubleLabyrinth/navicat-keygen/releases)下载最新的release。
+
+2. 使用`navicat-patcher.exe`替换掉`navicat.exe`和`libcc.dll`里的Navicat激活公钥。 
+
+   ```
+   navicat-patcher.exe [-dry-run] <Navicat Installation Path> [RSA-2048 PEM File Path]
+   ```
+
+   * `[-dry-run]`: 运行patcher但不对Navicat程序做任何修改。
+
+     __这个参数是可选的。__
+
+   * `<Navicat Installation Path>`: Navicat的完整安装路径。 
+     
+     __这个参数必须指定。__
+
+   * `[RSA-2048 PEM File Path]`: RSA-2048私钥文件的完整路径或相对路径。
+     
+     __这个参数是可选的。__ 如果未指定,`navicat-patcher.exe`将会在当前目录生成一个新的RSA-2048私钥文件。
+
+   __例如:(在cmd.exe中)__ 
+
+   ```
+   navicat-patcher.exe "C:\Program Files\PremiumSoft\Navicat Premium 12"
+   ```
+   
+   __Navicat Premium 12.1.22 简体中文版已通过测试__。下面将是一份样例输出:

+   Your organization: DoubleLabyrinth
+   Input request code (in Base64), input empty line to end:

+ 
+   之后你会被要求填入请求码。注意 __不要关闭命令行__.
+
+4. __断开网络__ 并打开Navicat。找到`注册`窗口,并填入keygen给你的序列号。然后点击`激活`按钮。
+
+5. 一般来说在线激活肯定会失败,这时候Navicat会询问你是否`手动激活`,直接选吧。
+
+6. 在`手动激活`窗口你会得到一个请求码,复制它并把它粘贴到keygen里。最后别忘了连按至少两下回车结束输入。
