# urllib3-secure-extra — Marker library to detect whether urllib3 was installed with the deprecated [secure] extra

License: permissive · Maintenance: abandoned · Downloads: 3.1M/mo

## What it is and what it does

urllib3-secure-extra is a minimal marker library designed to help detect whether urllib3 was installed with the now-deprecated [secure] extra. It exists to support conditional dependency resolution during a transition period when urllib3 was phasing out that extra. The package has no runtime dependencies and installs as a pure Python wheel.

This is a narrow-purpose tool created to bridge a specific compatibility gap in urllib3's dependency ecosystem. It was released on 2022-08-01 and has not been updated since, reflecting that it was meant as a temporary solution for a known deprecation rather than an ongoing library.

Use it for:

- Detect in setup.py or pyproject.toml whether urllib3 was installed with [secure] to conditionally require additional packages
- Maintain backward compatibility in projects that depend on urllib3's [secure] extra during its deprecation period
- Conditional marker expressions in dependency specifications to handle urllib3 installation variants

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Detects whether urllib3 was installed with the deprecated [secure] extra, providing a marker library for conditional dependency resolution.

No. The package is abandoned and was always a temporary bridge for a specific urllib3 deprecation. Unless you are maintaining legacy code that explicitly depends on detecting the [secure] extra, this library is no longer needed. Check urllib3's current documentation to understand how it now handles secure dependencies.

## Install

pip install urllib3-secure-extra
uv add urllib3-secure-extra
poetry add urllib3-secure-extra

## Installing urllib3-secure-extra

Before you install: Low install friction with no runtime dependencies, but the package is abandoned as of 2022-08-17 with no maintenance activity since its single release.

License in practice: MIT license permits use, modification, and distribution with minimal restrictions, making it safe to include in most projects.

Quickstart:

pip install urllib3-secure-extra

import urllib3_secure_extra

Verify before relying:

- Whether this marker library is still needed given urllib3's current handling of the [secure] extra deprecation
- Compatibility with modern urllib3 versions and Python versions released after 2022
