commit 40245c4a1cf221395c59d1f4bf274127045352f9 Author: Philipp Winter phw@nymity.ch Date: Mon Dec 7 10:23:44 2020 -0800
Update Azure's root CA certificate pins.
Microsoft recently updated the root CA certificates that are served to Azure clients. See the following article for more details: https://docs.microsoft.com/en-us/azure/security/fundamentals/tls-certificate...
This change broke meek-lite because none of its pins work anymore. That means that Tor Browser users can no longer use meek-azure or moat as both rely on meek-lite.
This patch fixes the problem by updating the certificate pins.
