If you’re getting the following error when trying to download files over https with wget:

… you might want to check out curl’s CA Extract. This allows you to extract a wget-compatible CA bundle file from those incuded with Mozilla software, which will allow verification of server certificates. They also make versions available that you can download directly, so you can simply download (for example) cacert.pem and then invoke wget thusly:
wget –ca-certificate=cacert.pem [https url]
