Feel free to get in touch with other community members on IRC, the mailing list or through issues here on GitHub. [See the README](/README.md) for contact information. ## Bug Reports You can file issues here on GitHub. Please try to include as much information as you can and under what conditions you saw the issue. ## Sending Pull Requests Patches should be submitted as pull requests (PR). Before submitting a PR: - Your code must run and pass all the automated tests before you submit your PR for review. "Work in progress" pull requests are allowed to be submitted, but should be clearly labeled as such and should not be merged until all tests pass and the code has been reviewed. NOTE: LLM generated patches are NOT accepted. See LLM section below. - Your patch should include new tests that cover your changes. It is your and your reviewer's responsibility to ensure your patch includes adequate tests. When submitting a PR: - **[Sign all your git commits](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification#ssh-commit-verification)**. We cannot accept any PR that does not have all commits signed. This is a policy put in place by our Security Operations team and is enforced by our CI processes. - You agree to license your code under the project's open source license ([MPL 2.0](/LICENSE)). - Base your branch off the current `main`. - Add both your code and new tests if relevant. - Run the test suite to make sure your code passes linting and tests. - Ensure your changes do not reduce code coverage of the test suite. - Please do not include merge commits in pull requests; include only commits with the new relevant code. ## Code Review This project is subject to the Mozilla [engineering practices and quality standards](https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Committing_Rules_and_Responsibilities). Every patch must be peer reviewed. ## Git Commit Guidelines We loosely follow the [Angular commit guidelines](https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#type) of `: ` where `type` must be one of: * **feat**: A new feature * **fix**: A bug fix * **bug**: alias for fix; A bug fix * **docs**: Documentation only changes * **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc) * **refactor**: A code change that neither fixes a bug or adds a feature * **perf**: A code change that improves performance * **test**: Adding missing tests * **chore**: Changes to the build process or auxiliary tools and libraries such as documentation generation * **breaks**: Contains a **BREAKING_CHANGE** to the existing execution environment. ### Subject The subject contains succinct description of the change: * use the imperative, present tense: "change" not "changed" nor "changes" * don't capitalize first letter * no dot (.) at the end ### Body In order to maintain a reference to the context of the commit, add `Closes #` if it closes a related issue or `Issue #` if it's a partial fix. You can also write a detailed description of the commit: Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes" It should include the motivation for the change and contrast this with previous behavior. ### Footer The footer should contain any information about **Breaking Changes** and is also the place to reference GitHub issues that this commit **Closes**. ### Example A properly formatted commit message should look like: ``` feat: give the developers a delicious cookie Properly formatted commit messages provide understandable history and documentation. This patch will provide a delicious cookie when all tests have passed and the commit message is properly formatted. BREAKING CHANGE: This patch requires developer to lower expectations about what "delicious" and "cookie" may mean. Some sadness may result. Closes #314, #975 ``` ## LLM generated content United States copyright and case law has determined that [content created by non-humans is not copyrightable](https://www.congress.gov/crs_external_products/LSB/PDF/LSB10922/LSB10922.8.pdf). This includes LLMs. If non-human generated code is introduced and not very explicitly noted, there is unsettled case law indicating that the entire work may not qualify as copyrightable. While you are certainly free to take the output of what an LLM may generate and modify it (significantly) in order to take full, personal ownership of the patch, you must be able to explain and detail the changes, answer questions about the impact, and be knowledgeable about the method of this codes production. I will, in good faith, accept that your patch is human created and verified and that you will affix your profile identity to this change. You acknowledge that if, at any point, your code is determined to have been geneated by non-human mechanisms, your submission will be immediately removed and your contributions with be exised as soon as possible solely at the discression of the main author of this repo. web-push-libs-pywebpush-c00b143/LICENSE000066400000000000000000000405251522517765400175660ustar00rootroot00000000000000Mozilla Public License Version 2.0 ================================== 1. Definitions -------------- 1.1. "Contributor" means each individual or legal entity that creates, contributes to the creation of, or owns Covered Software. 1.2. "Contributor Version" means the combination of the Contributions of others (if any) used by a Contributor and that particular Contributor's Contribution. 1.3. "Contribution" means Covered Software of a particular Contributor. 1.4. "Covered Software" means Source Code Form to which the initial Contributor has attached the notice in Exhibit A, the Executable Form of such Source Code Form, and Modifications of such Source Code Form, in each case including portions thereof. 1.5. "Incompatible With Secondary Licenses" means (a) that the initial Contributor has attached the notice described in Exhibit B to the Covered Software; or (b) that the Covered Software was made available under the terms of version 1.1 or earlier of the License, but not also under the terms of a Secondary License. 1.6. "Executable Form" means any form of the work other than Source Code Form. 1.7. "Larger Work" means a work that combines Covered Software with other material, in a separate file or files, that is not Covered Software. 1.8. "License" means this document. 1.9. "Licensable" means having the right to grant, to the maximum extent possible, whether at the time of the initial grant or subsequently, any and all of the rights conveyed by this License. 1.10. "Modifications" means any of the following: (a) any file in Source Code Form that results from an addition to, deletion from, or modification of the contents of Covered Software; or (b) any new file in Source Code Form that contains any Covered Software. 1.11. "Patent Claims" of a Contributor means any patent claim(s), including without limitation, method, process, and apparatus claims, in any patent Licensable by such Contributor that would be infringed, but for the grant of the License, by the making, using, selling, offering for sale, having made, import, or transfer of either its Contributions or its Contributor Version. 1.12. "Secondary License" means either the GNU General Public License, Version 2.0, the GNU Lesser General Public License, Version 2.1, the GNU Affero General Public License, Version 3.0, or any later versions of those licenses. 1.13. "Source Code Form" means the form of the work preferred for making modifications. 1.14. "You" (or "Your") means an individual or a legal entity exercising rights under this License. For legal entities, "You" includes any entity that controls, is controlled by, or is under common control with You.

License Grants and Conditions -------------------------------- 2.1. Grants 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, modify, display, perform, distribute, and otherwise exploit its Contributions, either on an unmodified basis, with Modifications, or as part of a Larger Work; and (b) under Patent Claims of such Contributor to make, use, sell, offer for sale, have made, import, and otherwise transfer either its Contributions or its Contributor Version. 2.2. Effective Date The licenses granted in Section 2.1 with respect to any Contribution become effective for each Contribution on the date the Contributor first 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.

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 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number. 10.2. Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, 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 Licenses If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached.

Source is available on [github](https://github.com/mozilla-services/pywebpush). Please note: This library was designated as a `Critical Project` by PyPi, it is currently maintained by [a single person](https://xkcd.com/2347/). I still accept PRs and Issues, but make of that what you will. ## Installation To work with this repo locally, you'll need to run `python -m venv venv`. Then `venv/bin/pip install --editable .` ## Usage In the browser, the promise handler for [registration.pushManager.subscribe()](https://developer.mozilla.org/en-US/docs/Web/API/PushManager/subscribe) returns a [PushSubscription](https://developer.mozilla.org/en-US/docs/Web/API/PushSubscription) object. This object has a .toJSON() method that will return a JSON object that contains all the info we need to encrypt and push data. As illustration, a `subscription_info` object may look like: ```json { "endpoint": "https://updates.push.services.mozilla.com/push/v1/gAA...", "keys": { "auth": "k8J...", "p256dh": "BOr..." } } ``` How you send the PushSubscription data to your backend, store it referenced to the user who requested it, and recall it when there's a new push subscription update is left as an exercise for the reader. _*Note:*_ Some platforms (like Microsoft Windows) require additional headers specified for the Push call. These additional headers are not standard and may be rejected by other Push services. Please see [Special Instructions](#special-instructions) below. ### Sending Data using `webpush()` One Call In many cases, your code will be sending a single message to many recipients. There's a "One Call" function which will make things easier. ```python from pywebpush import webpush webpush(subscription_info, data, vapid_private_key="Private Key or File Path[1]", vapid_claims={"sub": "mailto:YourEmailAddress"}) ``` This will encode `data`, add the appropriate VAPID auth headers if required and send it to the push server identified in the `subscription_info` block. #### Parameters _subscription_info_ - The `dict` of the subscription info (described above). _data_ - can be any serial content (string, bit array, serialized JSON, etc), but be sure that your receiving application is able to parse and understand it. (e.g. `data = "Mary had a little lamb."`) _content_type_ - specifies the form of Encryption to use, either `'aes128gcm'` or the deprecated `'aesgcm'`. NOTE that not all User Agents can decrypt `'aesgcm'`, so the library defaults to the RFC 8188 standard form. _vapid_claims_ - a `dict` containing the VAPID claims required for authorization (See [py_vapid](https://github.com/web-push-libs/vapid/tree/master/python) for more details). If `aud` is not specified, pywebpush will attempt to auto-fill from the `endpoint`. If `exp` is not specified or set in the past, it will be set to 12 hours from now. In both cases, the passed `dict` **will be mutated** after the call. _vapid_private_key_ - Either a path to a VAPID EC2 private key PEM file, or a string containing the DER representation. (See [py_vapid](https://github.com/web-push-libs/vapid/tree/master/python) for more details.) The `private_key` may be a base64 encoded DER formatted private key, or the path to an OpenSSL exported private key file. e.g. the output of: ```bash openssl ecparam -name prime256v1 -genkey -noout -out private_key.pem ``` #### Example ```python from pywebpush import webpush, WebPushException try: webpush( subscription_info={ "endpoint": "https://push.example.com/v1/12345", "keys": { "p256dh": "0123abcde...", "auth": "abc123..." }}, data="Mary had a little lamb, with a nice mint jelly", vapid_private_key="path/to/vapid_private.pem", vapid_claims={ "sub": "mailto:YourNameHere@example.org", } ) except WebPushException as ex: print("I'm sorry, Dave, but I can't do that: {}", repr(ex)) # Mozilla returns additional information in the body of the response. if ex.response is not None and ex.response.json(): extra = ex.response.json() print("Remote service replied with a {}:{}, {}", extra.code, extra.errno, extra.message ) ``` ### Methods If you expect to resend to the same recipient, or have more needs than just sending data quickly, you can pass just `wp = WebPusher(subscription_info)`. This will return a `WebPusher` object. The following methods are available: #### `.send(data, headers={}, ttl=0, reg_id="", content_encoding="aes128gcm", curl=False, timeout=None)` Send the data using additional parameters. On error, returns a `WebPushException` ##### Parameters _data_ Binary string of data to send _headers_ A `dict` containing any additional headers to send _ttl_ Message Time To Live on Push Server waiting for the client to reconnect (in seconds) _reg_id_ Google Cloud Messaging registration ID (will be extracted from endpoint if not specified) _content_encoding_ ECE content encoding type (defaults to "aes128gcm") _curl_ Do not execute the POST, but return as a `curl` command. This will write the encrypted content to a local file named `encrpypted.data`. This command is meant to be used for debugging purposes. _timeout_ timeout for requests POST query. See [requests documentation](http://docs.python-requests.org/en/master/user/quickstart/#timeouts). ##### Example to send to a user on Chrome: ```python WebPusher(subscription_info).send(data, headers, ttl) ``` #### `.encode(data, content_encoding="aes128gcm")` Encode the `data` for future use. On error, returns a `WebPushException` ##### Parameters _data_ Binary string of data to send _content_encoding_ ECE content encoding type (defaults to "aes128gcm") _*Note*_ This will return a `NoData` exception if the data is not present or empty. It is completely valid to send a WebPush notification with no data, but encoding is a no-op in that case. Best not to call it if you don't have data. ##### Example ```python encoded_data = WebPush(subscription_info).encode(data) ``` ## Stand Alone Webpush If you're not really into coding your own solution, there's also a "stand-alone" `pywebpush` command in the `./bin` directory. This uses two files: - the _data_ file, which contains the message to send, in whatever form you like. - the _subscription info_ file, which contains the subscription information as JSON encoded data. This is usually returned by the Push `subscribe` method and looks something like: ```json { "endpoint": "https://push...", "keys": { "auth": "ab01...", "p256dh": "aa02..." } } ``` If you're interested in just testing your applications WebPush interface, you could use the Command Line: ```bash ./bin/pywebpush --data stuff_to_send.data --info subscription.info ``` which will encrypt and send the contents of `stuff_to_send.data`. See `./bin/pywebpush --help` for available commands and options. ## Special Instructions ### Windows [Microsoft requires](https://learn.microsoft.com/en-us/windows/apps/design/shell/tiles-and-notifications/push-request-response-headers#request-parameters) one extra header and suggests several additional headers. Users have reported that not including these headers can cause notifications to fail to appear. These additional headers are non-standard and may be rejected by other platforms. You should be cautious including them with calls to non-Microsoft platforms, or to non-Microsoft destinations. As of 2024-Apr-19, Microsoft requires an `X-WNS-Type` header. As an example, you can include this header within the command line call: Content of the `windows_headers.json` file: ```json {"X-WNS-Type":"wns/toast", "TTL":600, "Content-Type": "text/xml"} ``` _*Note*_ : This includes both the `TTL` set to 10 minutes and the required matching `Content-Type` header for `wns/toast`. ```bash pywebpush --data stuff_to_send.xml \ --info edge_user_info.json \ --head windows_headers.json \ --claims vapid_claims.json ``` ### Google Cloud Messaging (GCM) Please note that GCM has been sunset by Google. Providers should use [Firebase Cloud Messaging](https://firebase.google.com/support/troubleshooter/fcm/tokens/gcm) instead. Please also note that sending messages directly to FCM is not supported by this library. In the past, you could use an insecure `gcm_key` as a proxy for the authentication service. [This was disabled in June 2024](https://firebase.google.com/docs/cloud-messaging/auth-server#authorize-legacy-protocol-send-requests). Sending WebPush messages to Google Chrome users should not be impacted by this change. web-push-libs-pywebpush-c00b143/README.rst000066400000000000000000000225701522517765400202500ustar00rootroot00000000000000Webpush Data encryption library for Python ========================================== This library is available on `pypi as pywebpush `__.
