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>.

This repository will tell you how Navicat offline activation works.
Previous previous code is archived in [`windows-archived`](https://notabug.org/doublesine/navicat-keygen/src/windows-archived) branch for the reason that previous previous code contains 3rd binary libraries and it gets quite big :-(
Previous code is archived in [`windows-archived2`](https://notabug.org/doublesine/navicat-keygen/src/windows-archived2) branch for the reason that Navicat has come to version 16.x.x which I think should be a milestone and I decide to obsolete previous code and rewrite new one.
When you git-clone this repo, please add `--single-branch` flag so that archived branches won't be cloned to your computer, which saves your time and disk.
```console
$ git clone -b windows --single-branch https://notabug.org/doublesine/navicat-keygen.git
```

# navicat-keygen for windows
这份repo将会告诉你Navicat是怎么完成离线激活的。
第一次归档的代码位于 [`windows-archived`](https://notabug.org/doublesine/navicat-keygen/src/windows-archived) 分支。归档原因：包含第三方二进制库，项目过大。
第二次归档的代码位于 [`windows-archived2`](https://notabug.org/doublesine/navicat-keygen/src/windows-archived2) 分支。归档原因：Navicat进入16.x.x版本，本项目打算进行重构。
当你clone该仓库的时候，请使用 `--single-branch` 选项，以此避免clone到已被归档的分支、以及节省你的时间和磁盘空间。
```console
$ git clone -b windows --single-branch https://notabug.org/doublesine/navicat-keygen.git
```

# Navicat Keygen - How does it work?
[中文版](how-does-it-work.zh-CN.md)
## 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.
1. At file offset `+0x01A12090` in `libcc.dll`, stored as __char string__:

```
__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.

4. __data[7]__ is Navicat product ID. (Thanks @dragonflylee and @Deltafox79)

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.
4. Encode the 256-byte-long data by Base64. The result is __Activation Code__.
5. After user input __Activation Code__, offline activation is done successfully.

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：
```
"D75125B70767B94145B47C1CB3C0755E

```
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：
```
0xFE 0xEA 0xBC 0x01
```
相应的十进制值为: `29158142`
3. 在`libcc.dll`中，文件偏移量`+0x01A11DA0`的地方，储存了加密公钥的第三部分，以 __字符串__ 的形式储存：

```
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
```
相应的十进制值为: `67673`
5. 在`libcc.dll`中，文件偏移量`+0x01A11D8C`的地方，储存了加密公钥的第五部分，以 __字符串__ 的形式储存：
```
"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：

```
这个加密的公钥可以用我的另外一个repo（[how-does-navicat-encrypt-password](https://github.com/DoubleLabyrinth/how-does-navicat-encrypt-password)）解密，其中密钥为`b'23970790'`。

__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 |
|------------|:---------:|:---------:|-----------------|
| English | 0xAC | 0x88 | |
| 简体中文 | 0xCE | 0x32 | |
| 繁體中文 | 0xAA | 0x99 | |
| 日本語 | 0xAD | 0x82 | @dragonflylee |
| Polski | 0xBB | 0x55 | @dragonflylee |
| Español | 0xAE | 0x10 | @dragonflylee |
| Français | 0xFA | 0x20 | @Deltafox79 |
| Deutsch | 0xB1 | 0x60 | @dragonflylee |
| 한국어 | 0xB5 | 0x60 | @dragonflylee |
| Русский | 0xEE | 0x16 | @dragonflylee |
| Português | 0xCD | 0x49 | @dragonflylee |
4. __data[7]__ 是Navicat产品ID。（感谢 @dragonflylee 和 @Deltafox79提供的数据）
|产品名 |Enterprise|Standard|Educational|Essentials|
|----------------------|:--------:|:------:|:---------:|:--------:|
|Navicat Report Viewer |0x0B | | | |
|Navicat Data Modeler 3| |0x84 |0x85 | |
|Navicat Premium |0x65 | |0x66 |0x67 |
|Navicat MySQL |0x68 |0x69 |0x6A |0x6B |
|Navicat PostgreSQL |0x6C |0x6D |0x6E |0x6F |
|Navicat Oracle |0x70 |0x71 |0x72 |0x73 |
|Navicat SQL Server |0x74 |0x75 |0x76 |0x77 |
|Navicat SQLite |0x78 |0x79 |0x7A |0x7B |
|Navicat MariaDB |0x7C |0x7D |0x7E |0x7F |
|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。

# navicat-keygen for windows - How to use?
[中文版](how-to-use.windows.zh-CN.md)
1. Use `navicat-patcher.exe` to replace __Navicat Activation Public Key__ that is stored in `libcc.dll`.
```
navicat-patcher.exe [-dry-run] <Navicat Install Path> [RSA-2048 PEM File Path]
```
* `[-dry-run]` Run patcher without applying any patches.
__This parameter is optional.__
* `<Navicat Install 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 16"
```
It has been tested on __Navicat Premium 16.0.7 English 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.

# navicat-keygen for windows - 如何使用这个注册机？
1. 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 Install 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 Install 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 16"
```
__Navicat Premium 16.0.7 英文版__ 已通过测试。下面将是一份样例输出：

2. 接下来使用`navicat-keygen.exe`来生成序列号和激活码
```
navicat-keygen.exe <-bin|-text> [-adv] <RSA-2048 Private Key File>

如果指定了`-bin`，`navicat-keygen.exe`最终将生成`license_file`文件。这个选项是给Navicat旧激活方式使用的。
如果指定了`-text`，`navicat-keygen.exe`最终将生成Base64样式的激活码。这个选项是给Navicat新激活方式使用的。
__这个参数必须指定。__
* `[-adv]`: 开启高级模式。
__这个参数是可选的。__ 如果指定了这个参数，`navicat-keygen.exe`将会要求你手工填写产品ID号、语言标识号。这个选项一般是给以后用的。
* `<RSA-2048 Private Key File>`: RSA-2048私钥文件的完整路径或相对路径。私钥必须是PEM格式的。
__这个参数必须指定。__
__例如：(在cmd.exe中)__
```console
navicat-keygen.exe -text .\RegPrivateKey.pem
```
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。

之后你会被要求填入请求码。注意 __不要关闭命令行__.
3. __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。
4. 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。
5. 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。
