Proof of Concept using Javascript to load the original certificate

The CVE-2020-0601 requires that the original CA certificate is in your certificate cache, this website is using Javascript to load an example page using the correct certificate and will then redirect you to a webpage serving a fake, crafted certificate as a test.

This test is meant to demonstrate the validity of a fake certificate that works for *.kudelskisecurity.com domains and *.microsoft.com domains, as well as for github.com. It could be used as a certificate to do a man-in-the-middle attack.
