||||||
|
Each Contributor hereby grants You a world-wide, royalty-free,
|
||||||
|
non-exclusive license:
|
||||||
|
|
||||||
|
(a) under intellectual property rights (other than patent or trademark)
|
||||||
|
Licensable by such Contributor to use, reproduce, make available,
|

|
2.2. Effective Date
|
||||||
|
|
||||||
|
The licenses granted in Section 2.1 with respect to any Contribution

||||||
|
distributes such Contribution.
|
||||||
|
|
||||||
|
2.3. Limitations on Grant Scope
|
||||||
|
|
||||||
|
The licenses granted in this Section 2 are the only rights granted under
|
||||||
|
this License. No additional rights or licenses will be implied from the
|
||||||
|
distribution or licensing of Covered Software under this License.
|
||||||
|
Notwithstanding Section 2.1(b) above, no patent license is granted by a
|
||||||
|
Contributor:
|
||||||
|
|
||||||
|
(a) for any code that a Contributor has removed from Covered Software;
|
||||||
|
or
|
||||||
|
|
||||||
|
(b) for infringements caused by: (i) Your and any other third party's
|
||||||
|
modifications of Covered Software, or (ii) the combination of its
|
||||||
|
Contributions with other software (except as part of its Contributor
|
||||||
|
Version); or
|
||||||
|
|
||||||
|
(c) under Patent Claims infringed by Covered Software in the absence of
|
||||||
|
its Contributions.
|
||||||
|
|
||||||
|
This License does not grant any rights in the trademarks, service marks,
|
||||||
|
or logos of any Contributor (except as may be necessary to comply with
|
||||||
|
the notice requirements in Section 3.4).
|
||||||
|
|
||||||
|
2.4. Subsequent Licenses
|
||||||
|
|
||||||
|
No Contributor makes additional grants as a result of Your choice to
|
||||||
|
distribute the Covered Software under a subsequent version of this
|
||||||
|
License (see Section 10.2) or under the terms of a Secondary License (if
|
||||||
|
permitted under the terms of Section 3.3).
|
||||||
|
|
||||||
|
2.5. Representation
|
||||||
|
|
||||||
|
Each Contributor represents that the Contributor believes its
|
||||||
|
Contributions are its original creation(s) or it has sufficient rights
|
||||||
|
to grant the rights to its Contributions conveyed by this License.
|
||||||
|
|
||||||
|
2.6. Fair Use
|
||||||
|
|
||||||
|
This License is not intended to limit any rights You have under
|
||||||
|
applicable copyright doctrines of fair use, fair dealing, or other
|
||||||
|
equivalents.
|
||||||
|
|
||||||
|
2.7. Conditions
|
||||||
|
|
||||||
|
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
|
||||||
|
in Section 2.1.
|
||||||
|
|
||||||
|
3. Responsibilities
|
||||||
|
-------------------
|
||||||
|
|
||||||
|
3.1. Distribution of Source Form
|
||||||
|
|
||||||
|
All distribution of Covered Software in Source Code Form, including any
|
||||||
|
Modifications that You create or to which You contribute, must be under
|
||||||
|
the terms of this License. You must inform recipients that the Source
|
||||||
|
Code Form of the Covered Software is governed by the terms of this
|
||||||
|
License, and how they can obtain a copy of this License. You may not
|
||||||
|
attempt to alter or restrict the recipients' rights in the Source Code
|
||||||
|
Form.
|
||||||
|
|
||||||
|
3.2. Distribution of Executable Form
|
||||||
|
|
||||||
|
If You distribute Covered Software in Executable Form then:
|
||||||
|
|
||||||
|
(a) such Covered Software must also be made available in Source Code
|
||||||
|
Form, as described in Section 3.1, and You must inform recipients of
|
||||||
|
the Executable Form how they can obtain a copy of such Source Code
|
||||||
|
Form by reasonable means in a timely manner, at a charge no more
|
||||||
|
than the cost of distribution to the recipient; and
|
||||||
|
|
||||||
|
(b) You may distribute such Executable Form under the terms of this
|
||||||
|
License, or sublicense it under different terms, provided that the
|
||||||
|
license for the Executable Form does not attempt to limit or alter
|
||||||
|
the recipients' rights in the Source Code Form under this License.
|
||||||
|
|
||||||
|
3.3. Distribution of a Larger Work
|
||||||
|
|
||||||
|
You may create and distribute a Larger Work under terms of Your choice,
|
||||||
|
provided that You also comply with the requirements of this License for
|
||||||
|
the Covered Software. If the Larger Work is a combination of Covered
|
||||||
|
Software with a work governed by one or more Secondary Licenses, and the
|
||||||
|
Covered Software is not Incompatible With Secondary Licenses, this
|
||||||
|
License permits You to additionally distribute such Covered Software
|
||||||
|
under the terms of such Secondary License(s), so that the recipient of
|
||||||
|
the Larger Work may, at their option, further distribute the Covered
|
||||||
|
Software under the terms of either this License or such Secondary
|
||||||
|
License(s).
|
||||||
|
|
||||||
|
3.4. Notices
|
||||||
|
|
||||||
|
You may not remove or alter the substance of any license notices
|
||||||
|
(including copyright notices, patent notices, disclaimers of warranty,
|
||||||
|
or limitations of liability) contained within the Source Code Form of
|
||||||
|
the Covered Software, except that You may alter any license notices to
|
||||||
|
the extent required to remedy known factual inaccuracies.
|
||||||
|
|
||||||
|
3.5. Application of Additional Terms
|
||||||
|
|
||||||
|
You may choose to offer, and to charge a fee for, warranty, support,
|
||||||
|
indemnity or liability obligations to one or more recipients of Covered
|
||||||
|
Software. However, You may do so only on Your own behalf, and not on
|
||||||
|
behalf of any Contributor. You must make it absolutely clear that any
|
||||||
|
such warranty, support, indemnity, or liability obligation is offered by
|
||||||
|
You alone, and You hereby agree to indemnify every Contributor for any
|
||||||
|
liability incurred by such Contributor as a result of warranty, support,
|
||||||
|
indemnity or liability terms You offer. You may include additional
|
||||||
|
disclaimers of warranty and limitations of liability specific to any
|
||||||
|
jurisdiction.
|
||||||
|
|
||||||
|
4. Inability to Comply Due to Statute or Regulation
|
||||||
|
---------------------------------------------------
|
||||||
|
|
||||||
|
If it is impossible for You to comply with any of the terms of this
|
||||||
|
License with respect to some or all of the Covered Software due to
|
||||||
|
statute, judicial order, or regulation then You must: (a) comply with
|
||||||
|
the terms of this License to the maximum extent possible; and (b)
|
||||||
|
describe the limitations and the code they affect. Such description must
|
||||||
|
be placed in a text file included with all distributions of the Covered
|
||||||
|
Software under this License. Except to the extent prohibited by statute
|
||||||
|
or regulation, such description must be sufficiently detailed for a
|
||||||
|
recipient of ordinary skill to be able to understand it.
|
||||||
|
|
||||||
|
5. Termination
|
||||||
|
--------------
|
||||||
|
|
||||||
|
5.1. The rights granted under this License will terminate automatically
|
||||||
|
if You fail to comply with any of its terms. However, if You become
|
||||||
|
compliant, then the rights granted under this License from a particular
|
||||||
|
Contributor are reinstated (a) provisionally, unless and until such
|
||||||
|
Contributor explicitly and finally terminates Your grants, and (b) on an
|
||||||
|
ongoing basis, if such Contributor fails to notify You of the
|
||||||
|
non-compliance by some reasonable means prior to 60 days after You have
|
||||||
|
come back into compliance. Moreover, Your grants from a particular
|
||||||
|
Contributor are reinstated on an ongoing basis if such Contributor
|
||||||
|
notifies You of the non-compliance by some reasonable means, this is the
|
||||||
|
first time You have received notice of non-compliance with this License
|
||||||
|
from such Contributor, and You become compliant prior to 30 days after
|
||||||
|
Your receipt of the notice.
|
||||||
|
|
||||||
|
5.2. If You initiate litigation against any entity by asserting a patent
|
||||||
|
infringement claim (excluding declaratory judgment actions,
|
||||||
|
counter-claims, and cross-claims) alleging that a Contributor Version
|
||||||
|
directly or indirectly infringes any patent, then the rights granted to
|
||||||
|
You by any and all Contributors for the Covered Software under Section
|
||||||
|
2.1 of this License shall terminate.
|
||||||
|
|
||||||
|
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
|
||||||
|
end user license agreements (excluding distributors and resellers) which
|
||||||
|
have been validly granted by You or Your distributors under this License
|
||||||
|
prior to termination shall survive termination.

||||||
|
* 6. Disclaimer of Warranty *
|
||||||
|
* ------------------------- *
|
||||||
|
* *
|
||||||
|
* Covered Software is provided under this License on an "as is" *
|
||||||
|
* basis, without warranty of any kind, either expressed, implied, or *
|
||||||
|
* statutory, including, without limitation, warranties that the *
|
||||||
|
* Covered Software is free of defects, merchantable, fit for a *
|
||||||
|
* particular purpose or non-infringing. The entire risk as to the *
|
||||||
|
* quality and performance of the Covered Software is with You. *
|
||||||
|
* Should any Covered Software prove defective in any respect, You *
|
||||||
|
* (not any Contributor) assume the cost of any necessary servicing, *
|
||||||
|
* repair, or correction. This disclaimer of warranty constitutes an *
|
||||||
|
* essential part of this License. No use of any Covered Software is *
|
||||||
|
* authorized under this License except under this disclaimer. *

|
* 7. Limitation of Liability *
|
||||||
|
* -------------------------- *
|
||||||
|
* *
|
||||||
|
* Under no circumstances and under no legal theory, whether tort *
|
||||||
|
* (including negligence), contract, or otherwise, shall any *
|
||||||
|
* Contributor, or anyone who distributes Covered Software as *
|
||||||
|
* permitted above, be liable to You for any direct, indirect, *
|
||||||
|
* special, incidental, or consequential damages of any character *
|
||||||
|
* including, without limitation, damages for lost profits, loss of *
|
||||||
|
* goodwill, work stoppage, computer failure or malfunction, or any *
|
||||||
|
* and all other commercial damages or losses, even if such party *
|
||||||
|
* shall have been informed of the possibility of such damages. This *
|
||||||
|
* limitation of liability shall not apply to liability for death or *
|
||||||
|
* personal injury resulting from such party's negligence to the *
|
||||||
|
* extent applicable law prohibits such limitation. Some *
|
||||||
|
* jurisdictions do not allow the exclusion or limitation of *
|
||||||
|
* incidental or consequential damages, so this exclusion and *
|
||||||
|
* limitation may not apply to You. *
|
||||||
|
* *
|

************************************************************************
|
||||||
|
|

|
8. Litigation
|
||||||
|
-------------
|
||||||
|
|
||||||
|
Any litigation relating to this License may be brought only in the
|
||||||
|
courts of a jurisdiction where the defendant maintains its principal
|
||||||
|
place of business and such litigation shall be governed by laws of that
|
||||||
|
jurisdiction, without reference to its conflict-of-law provisions.
|
||||||
|
Nothing in this Section shall prevent a party's ability to bring
|
||||||
|
cross-claims or counter-claims.
|
||||||
|
|
||||||
|
9. Miscellaneous
|
||||||
|
----------------
|
||||||
|
|
||||||
|
This License represents the complete agreement concerning the subject
|
||||||
|
matter hereof. If any provision of this License is held to be
|
||||||
|
unenforceable, such provision shall be reformed only to the extent
|
||||||
|
necessary to make it enforceable. Any law or regulation which provides
|
||||||
|
that the language of a contract shall be construed against the drafter
|
||||||
|
shall not be used to construe this License against a Contributor.
|
||||||
|
|
||||||
|
10. Versions of the License
|
||||||
|
---------------------------
|
||||||
|
|
||||||
|
10.1. New Versions
|
||||||
|
|
||||||
|
Mozilla Foundation is the license steward. Except as provided in Section
|
||||||
|

|
||||||
|

|
||||||
|
distinguishing version number.
|
||||||
|
|
||||||
|
10.2. Effect of New Versions
|
||||||
|
|

||||||
|
or under the terms of any subsequent version published by the license
|
||||||
|
steward.
|
||||||
|
|
||||||
|
10.3. Modified Versions
|
||||||
|
|
||||||
|
If you create software not governed by this License, and you want to
|
||||||
|
create a new license for such software, you may create and use a
|
||||||
|
modified version of this License if you rename the license and remove
|
||||||
|
any references to the name of the license steward (except to note that
|
||||||
|
such modified license differs from this License).
|
||||||
|
|
||||||
|
10.4. Distributing Source Code Form that is Incompatible With Secondary

<h1>BlueCrypt for the Browser</h1>
|
||||||
|
<p>BlueCrypt is universal crypto for the browser. It's lightweight, fast, and based on native webcrypto.
|
||||||
|
This means it's easy-to-use crypto in kilobytes, not megabytes.</p>
