I started down this path because ESXi s wget is not compiled with SSL and I wanted to download an OVA from a vendor s website directly onto the ESXi host which is on the other side of the world   I had to disable the firewall lazy  enable https out by editing the rules proper   created the python script   import ssl import shutil import tempfile import urllib request context   ssl  create unverified context    dlurl  https   somesite path whatever  with urllib request urlopen durl  context context  as response      with open  file ova    wb   as tmp file          shutil copyfileobj response  tmp file    ESXi libraries are kind of paired down but the open source weasel installer seemed to use urllib for https    so it inspired me to go down this path
