All,
As was just announced on the SCWG call, we (Rob at Sectigo) have recently generated the P521 set of Debian Weak Keys and added these to the upstream repository for
https://github.com/cabforum/Debian-weak-keys/.
We’ve now synced the fork available on
https://github.com/cabforum/Debian-weak-keys/, to also contain this set of keys.
As I mentioned on the call, we do not interpret this as a requirement change. Any CA issuing P-521 ECC certificates was already required to confirm no Debian Weak Keys were being used, and would have had to generate this batch themselves.
Regards,
Martijn
