How Can I Update OpenSSL in My Python 2.7 Environment?

Updating OpenSSL in Python 2.7

In Python 2.7, the openssl module provides an interface to the OpenSSL library. By default, Python relies on the system-wide installation of OpenSSL. However, you may encounter situations where you need to update OpenSSL within your Python environment.

To determine which version of OpenSSL Python is using, import the ssl module and access the OPENSSL_VERSION attribute:

<code class="python">>>> import ssl
>>> ssl.OPENSSL_VERSION
'OpenSSL 0.9.8x 10 May 2012'</code>

If you need to update OpenSSL, you can proceed by manually installing the latest version and updating the system-wide symlinks. However, this approach can be complex and may require additional configurations depending on your operating system.

A more reliable solution is to install a new version of Python that includes the updated OpenSSL library. For example, on macOS using Homebrew:

$ brew update
$ brew install openssl
$ brew install python --with-brewed-openssl

This will install a new copy of Python linked to the brewed OpenSSL library. You can then symlink this new Python to the system-wide path:

$ sudo ln -s /usr/local/bin/python /usr/bin/python

After following these steps, Python will now use the updated OpenSSL version:

$ python --version
Python 2.7.8

$ python -c "import ssl; print ssl.OPENSSL_VERSION"
OpenSSL 1.0.1j 15 Oct 2014

Remember, this approach requires installing a fresh copy of Python, ensuring that you have the necessary permissions for the system-wide directory, and making sure that the new Python installation is visible in your path.
