+# Vulnerability Disclosure
+
+If you think you have found a potential security vulnerability in
+requests, please open a [draft Security Advisory](https://github.com/psf/requests/security/advisories/new)
+via GitHub. We will coordinate verification and next steps through
+that secure medium.
+
+If English is not your first language, please try to describe the
+problem and its impact to the best of your ability. For greater detail,
+please use your native language and we will try our best to translate it
+using online services.
+
+Please also include the code you used to find the problem and the
+shortest amount of code necessary to reproduce it.
+
+Please do not disclose this to anyone else. We will retrieve a CVE
+identifier if necessary and give you full credit under whatever name or
+alias you provide. We will only request an identifier when we have a fix
+and can publish it in a release.
+
+We will respect your privacy and will only publicize your involvement if
+you grant us permission.
+
+## Process
+
+This following information discusses the process the requests project
+follows in response to vulnerability disclosures. If you are disclosing
+a vulnerability, this section of the documentation lets you know how we
+will respond to your disclosure.
+
+### Timeline
+
+When you report an issue, one of the project members will respond to you
+within two days *at the outside*. In most cases responses will be
+faster, usually within 12 hours. This initial response will at the very
+least confirm receipt of the report.
+
+If we were able to rapidly reproduce the issue, the initial response
+will also contain confirmation of the issue. If we are not, we will
+often ask for more information about the reproduction scenario.
+
+Our goal is to have a fix for any vulnerability released within two
+weeks of the initial disclosure. This may potentially involve shipping
+an interim release that simply disables function while a more mature fix
+can be prepared, but will in the vast majority of cases mean shipping a
+complete release as soon as possible.
+
+Throughout the fix process we will keep you up to speed with how the fix
+is progressing. Once the fix is prepared, we will notify you that we
+believe we have a fix. Often we will ask you to confirm the fix resolves
+the problem in your environment, especially if we are not confident of
+our reproduction scenario.
+
+At this point, we will prepare for the release. We will obtain a CVE
+number if one is required, providing you with full credit for the
+discovery. We will also decide on a planned release date, and let you
+know when it is. This release date will *always* be on a weekday.
+
+At this point we will reach out to our major downstream packagers to
+notify them of an impending security-related patch so they can make
+arrangements. In addition, these packagers will be provided with the
+intended patch ahead of time, to ensure that they are able to promptly
+release their downstream packages. Currently the list of people we
+actively contact *ahead of a public release* is:
+
+-   Python Maintenance Team, Red Hat (python-maint@redhat.com)
+-   Daniele Tricoli, Debian (@eriol)
+
+We will notify these individuals at least a week ahead of our planned
+release date to ensure that they have sufficient time to prepare. If you
+believe you should be on this list, please let one of the maintainers
+know at one of the email addresses at the top of this article.
+
+On release day, we will push the patch to our public repository, along
+with an updated changelog that describes the issue and credits you. We
+will then issue a PyPI release containing the patch.
+
+At this point, we will publicise the release. This will involve mails to
+mailing lists, Tweets, and all other communication mechanisms available
+to the core team.
+
+We will also explicitly mention which commits contain the fix to make it
+easier for other distributors and users to easily patch their own
+versions of requests if upgrading is not an option.

+
+2.32.5 (2025-08-18)
+-------------------
+
 **Bugfixes**
 
--   \[Short description of non-trivial change.\]
+- The SSLContext caching feature originally introduced in 2.32.0 has created
+  a new class of issues in Requests that have had negative impact across a number
+  of use cases. The Requests team has decided to revert this feature as long term
+  maintenance of it is proving to be unsustainable in its current iteration.
+
+**Deprecations**
+- Added support for Python 3.14.
+- Dropped support for Python 3.8 following its end of support.
+
+2.32.4 (2025-06-10)
+-------------------
+
+**Security**
+- CVE-2024-47081 Fixed an issue where a maliciously crafted URL and trusted
+  environment will retrieve credentials for the wrong hostname/machine from a
+  netrc file.
+
+**Improvements**
+- Numerous documentation improvements
+
+**Deprecations**
+- Added support for pypy 3.11 for Linux and macOS.
+- Dropped support for pypy 3.9 following its end of support.
+
+
+2.32.3 (2024-05-29)
+-------------------
+
+**Bugfixes**
+- Fixed bug breaking the ability to specify custom SSLContexts in sub-classes of
+  HTTPAdapter. (#6716)
+- Fixed issue where Requests started failing to run on Python versions compiled
+  without the `ssl` module. (#6724)
+
+2.32.2 (2024-05-21)
+-------------------
+
+**Deprecations**
+- To provide a more stable migration for custom HTTPAdapters impacted
+  by the CVE changes in 2.32.0, we've renamed `_get_connection` to
+  a new public API, `get_connection_with_tls_context`. Existing custom
+  HTTPAdapters will need to migrate their code to use this new API.
+  `get_connection` is considered deprecated in all versions of Requests>=2.32.0.
+
+  A minimal (2-line) example has been provided in the linked PR to ease
+  migration, but we strongly urge users to evaluate if their custom adapter
+  is subject to the same issue described in CVE-2024-35195. (#6710)
+
+2.32.1 (2024-05-20)
+-------------------
+
+**Bugfixes**
+- Add missing test certs to the sdist distributed on PyPI.
+
+
+2.32.0 (2024-05-20)
+-------------------
+
+**Security**
+- Fixed an issue where setting `verify=False` on the first request from a
+  Session will cause subsequent requests to the _same origin_ to also ignore
+  cert verification, regardless of the value of `verify`.
+  (https://github.com/psf/requests/security/advisories/GHSA-9wx4-h78v-vm56)
+
+**Improvements**
+- `verify=True` now reuses a global SSLContext which should improve
+  request time variance between first and subsequent requests. It should
+  also minimize certificate load time on Windows systems when using a Python
+  version built with OpenSSL 3.x. (#6667)
+- Requests now supports optional use of character detection
+  (`chardet` or `charset_normalizer`) when repackaged or vendored.
+  This enables `pip` and other projects to minimize their vendoring
+  surface area. The `Response.text()` and `apparent_encoding` APIs
+  will default to `utf-8` if neither library is present. (#6702)
+
+**Bugfixes**
+- Fixed bug in length detection where emoji length was incorrectly
+  calculated in the request content-length. (#6589)
+- Fixed deserialization bug in JSONDecodeError. (#6629)
+- Fixed bug where an extra leading `/` (path separator) could lead
+  urllib3 to unnecessarily reparse the request URI. (#6644)
+
+**Deprecations**
+
+- Requests has officially added support for CPython 3.12 (#6503)
+- Requests has officially added support for PyPy 3.9 and 3.10 (#6641)
+- Requests has officially dropped support for CPython 3.7 (#6642)
+- Requests has officially dropped support for PyPy 3.7 and 3.8 (#6641)
+
+**Documentation**
+- Various typo fixes and doc improvements.
+
+**Packaging**
+- Requests has started adopting some modern packaging practices.
+  The source files for the projects (formerly `requests`) is now located
+  in `src/requests` in the Requests sdist. (#6506)
+- Starting in Requests 2.33.0, Requests will migrate to a PEP 517 build system
+  using `hatchling`. This should not impact the average user, but extremely old
+  versions of packaging utilities may have issues with the new packaging format.
+
+
+2.31.0 (2023-05-22)
+-------------------
+
+**Security**
+- Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
+  forwarding of `Proxy-Authorization` headers to destination servers when
+  following HTTPS redirects.
+
+  When proxies are defined with user info (`https://user:pass@proxy:8080`), Requests
+  will construct a `Proxy-Authorization` header that is attached to the request to
+  authenticate with the proxy.
+
+  In cases where Requests receives a redirect response, it previously reattached
+  the `Proxy-Authorization` header incorrectly, resulting in the value being
+  sent through the tunneled connection to the destination server. Users who rely on
+  defining their proxy credentials in the URL are *strongly* encouraged to upgrade
+  to Requests 2.31.0+ to prevent unintentional leakage and rotate their proxy
+  credentials once the change has been fully deployed.
+
+  Users who do not use a proxy or do not supply their proxy credentials through
+  the user information portion of their proxy URL are not subject to this
+  vulnerability.
+
+  Full details can be read in our [Github Security Advisory](https://github.com/psf/requests/security/advisories/GHSA-j8r2-6x86-q33q)
+  and [CVE-2023-32681](https://nvd.nist.gov/vuln/detail/CVE-2023-32681).
+
+
+2.30.0 (2023-05-03)
+-------------------
+
+**Dependencies**
+- ⚠️ Added support for urllib3 2.0. ⚠️
+
+  This may contain minor breaking changes so we advise careful testing and
+  reviewing https://urllib3.readthedocs.io/en/latest/v2-migration-guide.html
+  prior to upgrading.
+
+  Users who wish to stay on urllib3 1.x can pin to `urllib3<2`.
+
+2.29.0 (2023-04-26)
+-------------------
+
+**Improvements**
+
+- Requests now defers chunked requests to the urllib3 implementation to improve
+  standardization. (#6226)
+- Requests relaxes header component requirements to support bytes/str subclasses. (#6356)
+
+2.28.2 (2023-01-12)
+-------------------
+
+**Dependencies**
+
+- Requests now supports charset\_normalizer 3.x. (#6261)
+
+**Bugfixes**
+
+- Updated MissingSchema exception to suggest https scheme rather than http. (#6188)
+
+2.28.1 (2022-06-29)
+-------------------
+
+**Improvements**
+
+- Speed optimization in `iter_content` with transition to `yield from`. (#6170)
+
+**Dependencies**
+
+- Added support for chardet 5.0.0 (#6179)
+- Added support for charset-normalizer 2.1.0 (#6169)
+
+2.28.0 (2022-06-09)
+-------------------
+
+**Deprecations**
+
+- ⚠️ Requests has officially dropped support for Python 2.7. ⚠️ (#6091)
+- Requests has officially dropped support for Python 3.6 (including pypy3.6). (#6091)
+
+**Improvements**
+
+- Wrap JSON parsing issues in Request's JSONDecodeError for payloads without
+  an encoding to make `json()` API consistent. (#6097)
+- Parse header components consistently, raising an InvalidHeader error in
+  all invalid cases. (#6154)
+- Added provisional 3.11 support with current beta build. (#6155)
+- Requests got a makeover and we decided to paint it black. (#6095)
+
+**Bugfixes**
+
+- Fixed bug where setting `CURL_CA_BUNDLE` to an empty string would disable
+  cert verification. All Requests 2.x versions before 2.28.0 are affected. (#6074)
+- Fixed urllib3 exception leak, wrapping `urllib3.exceptions.SSLError` with
+  `requests.exceptions.SSLError` for `content` and `iter_content`. (#6057)
+- Fixed issue where invalid Windows registry entries caused proxy resolution
+  to raise an exception rather than ignoring the entry. (#6149)
+- Fixed issue where entire payload could be included in the error message for
+  JSONDecodeError. (#6036)
+
+2.27.1 (2022-01-05)
+-------------------
+
+**Bugfixes**
+
+- Fixed parsing issue that resulted in the `auth` component being
+  dropped from proxy URLs. (#6028)
+
+2.27.0 (2022-01-03)
+-------------------
+
+**Improvements**
+
+- Officially added support for Python 3.10. (#5928)
+
+- Added a `requests.exceptions.JSONDecodeError` to unify JSON exceptions between
+  Python 2 and 3. This gets raised in the `response.json()` method, and is
+  backwards compatible as it inherits from previously thrown exceptions.
+  Can be caught from `requests.exceptions.RequestException` as well. (#5856)
+
+- Improved error text for misnamed `InvalidSchema` and `MissingSchema`
+  exceptions. This is a temporary fix until exceptions can be renamed
+  (Schema->Scheme). (#6017)
+
+- Improved proxy parsing for proxy URLs missing a scheme. This will address
+  recent changes to `urlparse` in Python 3.9+. (#5917)
+
+**Bugfixes**
+
+- Fixed defect in `extract_zipped_paths` which could result in an infinite loop
+  for some paths. (#5851)
+
+- Fixed handling for `AttributeError` when calculating length of files obtained
+  by `Tarfile.extractfile()`. (#5239)
+
+- Fixed urllib3 exception leak, wrapping `urllib3.exceptions.InvalidHeader` with
+  `requests.exceptions.InvalidHeader`. (#5914)
+
+- Fixed bug where two Host headers were sent for chunked requests. (#5391)
+
+- Fixed regression in Requests 2.26.0 where `Proxy-Authorization` was
+  incorrectly stripped from all requests sent with `Session.send`. (#5924)
+
+- Fixed performance regression in 2.26.0 for hosts with a large number of
+  proxies available in the environment. (#5924)
+
+- Fixed idna exception leak, wrapping `UnicodeError` with
+  `requests.exceptions.InvalidURL` for URLs with a leading dot (.) in the
+  domain. (#5414)
+
+**Deprecations**
+
+- Requests support for Python 2.7 and 3.6 will be ending in 2022. While we
+  don't have exact dates, Requests 2.27.x is likely to be the last release
+  series providing support.
+
+2.26.0 (2021-07-13)
+-------------------
+
+**Improvements**
+
+- Requests now supports Brotli compression, if either the `brotli` or
+  `brotlicffi` package is installed. (#5783)
+
+- `Session.send` now correctly resolves proxy configurations from both
+  the Session and Request. Behavior now matches `Session.request`. (#5681)
+
+**Bugfixes**
+
+- Fixed a race condition in zip extraction when using Requests in parallel
+  from zip archive. (#5707)
+
+**Dependencies**
+
+- Instead of `chardet`, use the MIT-licensed `charset_normalizer` for Python3
+  to remove license ambiguity for projects bundling requests. If `chardet`
+  is already installed on your machine it will be used instead of `charset_normalizer`
+  to keep backwards compatibility. (#5797)
+
+  You can also install `chardet` while installing requests by
+  specifying `[use_chardet_on_py3]` extra as follows:
+
+    ```shell
+    pip install "requests[use_chardet_on_py3]"
+    ```
+
+  Python2 still depends upon the `chardet` module.
+
+- Requests now supports `idna` 3.x on Python 3. `idna` 2.x will continue to
+  be used on Python 2 installations. (#5711)
+
+**Deprecations**
+
+- The `requests[security]` extra has been converted to a no-op install.
+  PyOpenSSL is no longer the recommended secure option for Requests. (#5867)
+
+- Requests has officially dropped support for Python 3.5. (#5867)
+
+2.25.1 (2020-12-16)
+-------------------
+
+**Bugfixes**
+
+- Requests now treats `application/json` as `utf8` by default. Resolving
+  inconsistencies between `r.text` and `r.json` output. (#5673)
+
+**Dependencies**
+
+- Requests now supports chardet v4.x.
+
+2.25.0 (2020-11-11)
+-------------------
+
+**Improvements**
+
+- Added support for NETRC environment variable. (#5643)
+
+**Dependencies**
+
+- Requests now supports urllib3 v1.26.
+
+**Deprecations**
+
+- Requests v2.25.x will be the last release series with support for Python 3.5.
+- The `requests[security]` extra is officially deprecated and will be removed
+  in Requests v2.26.0.
+
+2.24.0 (2020-06-17)
+-------------------
+
+**Improvements**
+
+- pyOpenSSL TLS implementation is now only used if Python
+  either doesn't have an `ssl` module or doesn't support
+  SNI. Previously pyOpenSSL was unconditionally used if available.
+  This applies even if pyOpenSSL is installed via the
+  `requests[security]` extra (#5443)
+
+- Redirect resolution should now only occur when
+  `allow_redirects` is True. (#5492)
+
+- No longer perform unnecessary Content-Length calculation for
+  requests that won't use it. (#5496)
+
+2.23.0 (2020-02-19)
+-------------------
+
+**Improvements**
+
+- Remove defunct reference to `prefetch` in Session `__attrs__` (#5110)
+
+**Bugfixes**
+
+- Requests no longer outputs password in basic auth usage warning. (#5099)
+
+**Dependencies**
+
+- Pinning for `chardet` and `idna` now uses major version instead of minor.
+  This hopefully reduces the need for releases every time a dependency is updated.

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-See [the similar code, sans Requests](https://gist.github.com/973705).
+Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your `PUT` & `POST` data — but nowadays, just use the `json` method!
 
-[![image](https://raw.githubusercontent.com/requests/requests/master/docs/_static/requests-logo-small.png)](http://docs.python-requests.org/)
+Requests is one of the most downloaded Python packages today, pulling in around `30M downloads / week`— according to GitHub, Requests is currently [depended upon](https://github.com/psf/requests/network/dependents?package_id=UGFja2FnZS01NzA4OTExNg%3D%3D) by `1,000,000+` repositories. You may certainly put your trust in this code.
 
-Requests allows you to send *organic, grass-fed* HTTP/1.1 requests,
-without the need for manual labor. There's no need to manually add query
-strings to your URLs, or to form-encode your POST data. Keep-alive and
-HTTP connection pooling are 100% automatic, thanks to
-[urllib3](https://github.com/shazow/urllib3).

-1.  Become more familiar with the project by reading our [Contributor's Guide](http://docs.python-requests.org/en/latest/dev/contributing/) and our [development philosophy](http://docs.python-requests.org/en/latest/dev/philosophy/).
-2.  Check for open issues or open a fresh issue to start a discussion
-    around a feature idea or a bug. There is a [Contributor
-    Friendly](https://github.com/requests/requests/issues?direction=desc&labels=Contributor+Friendly&page=1&sort=updated&state=open)
-    tag for issues that should be ideal for people who are not very
-    familiar with the codebase yet.
-3.  Fork [the repository](https://github.com/requests/requests) on
-    GitHub to start making your changes to the **master** branch (or
-    branch off of it).
-4.  Write a test which shows that the bug was fixed or that the feature
-    works as expected.
-5.  Send a pull request and bug the maintainer until it gets merged and
-    published. :) Make sure to add yourself to
-    [AUTHORS](https://github.com/requests/requests/blob/master/AUTHORS.rst).

+
+## Cloning the repository
+
+When cloning the Requests repository, you may need to add the `-c
+fetch.fsck.badTimezone=ignore` flag to avoid an error about a bad commit timestamp (see
+[this issue](https://github.com/psf/requests/issues/2690) for more background):
+
+```shell
+git clone -c fetch.fsck.badTimezone=ignore https://github.com/psf/requests.git
+```
+
+You can also apply this setting to your global Git config:
+
+```shell
+git config --global fetch.fsck.badTimezone ignore
+```

-Community Sponsors
-==================
-
-**tl;dr**: Requests development is currently `funded by the Python community <https://www.kennethreitz.org/requests3>`_, and
-some wonderful organizations that utilize the software in their businesses.
-
-
--------------------
-
-
-Requests is one of the most heavily–utilized Python packages in the world.
-
-It is used by major corporations worldwide for all tasks, both small and large — from writing one–off scripts to orchestrating millions of dollars of critical infrastructure.
-
-It's even embedded within pip, that tool that you use to install packages and deploy with every day!
-
-After losing our primary open source maintainer (who was sponsored by a company to work on Requests, and other projects, full–time), we are seeking community financial contributions towards the development of Requests 3.0.
-
-Patron Sponsors

-
-Please also include the code you used to find the problem and the shortest
-amount of code necessary to reproduce it.
-
-Please do not disclose this to anyone else. We will retrieve a CVE identifier
-if necessary and give you full credit under whatever name or alias you provide.

-
-Process
--------
-
-This following information discusses the process the requests project follows
-in response to vulnerability disclosures. If you are disclosing a
-vulnerability, this section of the documentation lets you know how we will
-respond to your disclosure.
-
-Timeline
-~~~~~~~~
-
-When you report an issue, one of the project members will respond to you within
-two days *at the outside*. In most cases responses will be faster, usually
-within 12 hours. This initial response will at the very least confirm receipt
-of the report.
-
-If we were able to rapidly reproduce the issue, the initial response will also
-contain confirmation of the issue. If we are not, we will often ask for more
-information about the reproduction scenario.
-
-Our goal is to have a fix for any vulnerability released within two weeks of
-the initial disclosure. This may potentially involve shipping an interim
-release that simply disables function while a more mature fix can be prepared,
-but will in the vast majority of cases mean shipping a complete release as soon
-as possible.
-
-Throughout the fix process we will keep you up to speed with how the fix is
-progressing. Once the fix is prepared, we will notify you that we believe we
-have a fix. Often we will ask you to confirm the fix resolves the problem in
-your environment, especially if we are not confident of our reproduction
-scenario.
-
-At this point, we will prepare for the release. We will obtain a CVE number
-if one is required, providing you with full credit for the discovery. We will
-also decide on a planned release date, and let you know when it is. This
-release date will *always* be on a weekday.
-
-At this point we will reach out to our major downstream packagers to notify
-them of an impending security-related patch so they can make arrangements. In
-addition, these packagers will be provided with the intended patch ahead of
-time, to ensure that they are able to promptly release their downstream
-packages. Currently the list of people we actively contact *ahead of a public
-release* is:
-
-- Jeremy Cline, Red Hat (@jeremycline)
-- Daniele Tricoli, Debian (@eriol)
-
-We will notify these individuals at least a week ahead of our planned release
-date to ensure that they have sufficient time to prepare. If you believe you
-should be on this list, please let one of the maintainers know at one of the
-email addresses at the top of this article.
-
-On release day, we will push the patch to our public repository, along with an
-updated changelog that describes the issue and credits you. We will then issue
-a PyPI release containing the patch.
-
-At this point, we will publicise the release. This will involve mails to
-mailing lists, Tweets, and all other communication mechanisms available to the
-core team.
-
-We will also explicitly mention which commits contain the fix to make it easier
-for other distributors and users to easily patch their own versions of requests
-if upgrading is not an option.

-Kenneth Reitz's Code Style™
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The Requests codebase uses the `PEP 8`_ code style.
-
-In addition to the standards outlined in PEP 8, we have a few guidelines:
-
-- Line-length can exceed 79 characters, to 100, when convenient.
-- Line-length can exceed 100 characters, when doing otherwise would be *terribly* inconvenient.
-- Always use single-quoted strings (e.g. ``'#flatearth'``), unless a single-quote occurs within the string.
-
-Additionally, one of the styles that PEP8 recommends for `line continuations`_
-completely lacks all sense of taste, and is not to be permitted within
-the Requests codebase::
-
-    # Aligned with opening delimiter.
-    foo = long_function_name(var_one, var_two,
-                             var_three, var_four)
-
-No. Just don't. Please.
-
-Docstrings are to follow the following syntaxes::
-
-    def the_earth_is_flat():
-        """NASA divided up the seas into thirty-three degrees."""
-        pass
-

-
-Requests is an open but opinionated library, created by an open but opinionated developer.
-
-
-Management Style
-~~~~~~~~~~~~~~~~
-
-`Kenneth Reitz <https://www.kennethreitz.org/>`_ is the BDFL. He has final say in any decision related to the Requests project. Kenneth is responsible for the direction and form of the library, as well as its presentation. In addition to making decisions based on technical merit, he is responsible for making decisions based on the development philosophy of Requests.
-
-`Ian Cordasco <http://www.coglib.com/~icordasc/>`_, `Cory Benfield <https://lukasa.co.uk/about/>`_, and `Nate Prewitt <https://www.nateprewitt.com/>`_ are the core contributors. They are responsible for triaging bug reports, reviewing pull requests and ensuring that Kenneth is kept up to speed with developments around the library. The day-to-day managing of the project is done by the core contributors. They are responsible for making judgements about whether or not a feature request is likely to be accepted by Kenneth. Their word is, in some ways, more final than Kenneth's.

-Values
-~~~~~~
-
-- Simplicity is always better than functionality.
-- Listen to everyone, then disregard it.
-- The API is all that matters. Everything else is secondary.
-- Fit the 90% use-case. Ignore the nay-sayers.
-
-Semantic Versioning
-~~~~~~~~~~~~~~~~~~~
-
-For many years, the open source community has been plagued with version number dystonia. Numbers vary so greatly from project to project, they are practically meaningless.
-
-Requests uses `Semantic Versioning <https://semver.org/>`_. This specification seeks to put an end to this madness with a small set of practical guidelines for you and your colleagues to use in your next project.
-
-Standard Library?
-~~~~~~~~~~~~~~~~~
-
-Requests has no *active* plans to be included in the standard library. This decision has been discussed at length with Guido as well as numerous core developers.
-

-    <script async class="speakerdeck-embed" data-id="68f22f0841734d848315c618111b13ea" data-ratio="1.33333333333333" src="//speakerdeck.com/assets/embed.js"></script>
-
-Essentially, the standard library is where a library goes to die. It is appropriate for a module to be included when active development is no longer necessary.
-
-Linux Distro Packages
-~~~~~~~~~~~~~~~~~~~~~
-
-Distributions have been made for many Linux repositories, including: Ubuntu, Debian, RHEL, and Arch.
-
-These distributions are sometimes divergent forks, or are otherwise not kept up-to-date with the latest code and bugfixes. PyPI (and its mirrors) and GitHub are the official distribution sources; alternatives are not supported by the Requests project.

If you pass an ``OrderedDict`` to the ``headers`` keyword argument, that will provide the headers with an ordering. *However*, the ordering of the default headers used by Requests will be preferred, which means that if you override default headers in the ``headers`` keyword argument, they may appear out of order compared to other headers in that keyword argument.

+Requests HTTP Library
+~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+   >>> import requests
+   >>> r = requests.get('https://www.python.org')
+   >>> r.status_code
+   200
+   >>> b'Python is a programming language' in r.content
+   True
+
+... or POST:
+
+   >>> payload = dict(key1='value1', key2='value2')
+   >>> r = requests.post('https://httpbin.org/post', data=payload)
+   >>> print(r.text)
+   {
+     ...
+     "form": {
+       "key1": "value1",
+       "key2": "value2"
+     },
+     ...
+   }
+
+The other HTTP methods are supported - see `requests.api`. Full documentation
+is at <https://requests.readthedocs.io>.

+        to use to select a connection from a given urllib3 Connection Pool.

+        dictionary:
+
+        * If ``verify`` is ``True``, ``"ssl_context"`` will be set and will be the
+          default Requests SSL Context
+        * If ``verify`` is ``False``, ``"ssl_context"`` will not be set but
+          ``"cert_reqs"`` will be set
+        * If ``verify`` is a string, (i.e., it is a user-specified trust bundle)
+          ``"ca_certs"`` will be set if the string is not a directory recognized
+          by :py:func:`os.path.isdir`, otherwise ``"ca_cert_dir"`` will be
+          set.
+        * If ``"cert"`` is specified, ``"cert_file"`` will always be set. If
+          ``"cert"`` is a tuple with a second item, ``"key_file"`` will also
+          be present
+
+        To override these settings, one may subclass this class, call this
+        method and use the above logic to change parameters as desired. For
+        example, if one wishes to use a custom :py:class:`ssl.SSLContext` one
+        must both set ``"ssl_context"`` and based on what else they require,
