Just to be clear, I am currently dumping elliptic curve keys from the tls certificate transparency logs, and will then be running an optimized mass-cracker tool that I'll use to check a few trillion weak private keys against the entire set simultaneously using sparse bloom filters.

The scanner (which is being heavily cribbed from my mass cryptocurrency key cracker "brainflayer") should be able to scan hundreds of thousands if not millions of keys per curve per second per core.

I am not aware of anyone else having previously done this, so hold on to your butts.
