title: Configuring trusted-host for setuptools
body: <p>When I call <code>pip install</code> for a PyPI repository with an untrusted certificate, I can skip SSL verification by using --trusted-host option:</p>
  
  <pre><code>$ pip install googleapis-common-protos --index-url https://maven.mycompany.org/artifactory/api/pypi/pypi-virtual/simple --trusted-host maven.mycompany.org
  Looking in indexes: https://maven.mycompany.org/artifactory/api/pypi/pypi-virtual/simple
