Script - Generate new (2048bit) self-signed certificate
From Edge Threat Management Wiki - Arista
What it is
This script will replace your current certificate with a new 2048 bit self signed certificate. If your GUI is not loading after importing a certificate this patch will get it back to a state where you can login.
This patch will invalidate your existing cert, so make sure to backup any purchased certificates before running it.
