If reporting a suspected mis-issuance has the effect that revocation is expected, then I fear this will stifle CAs willingness to report. It's the chilling effect that we IMHO already see in current ongoing discussions. ☹
I admit that I'm also at a point where I rather keep quiet than voicing my opinion. Rgds Roman -----Original Message----- From: Watson Ladd <[email protected]> Sent: Mittwoch, 19.

Certainly in a complex situation the CA might be genuinely unsure if mississuance happened. However it's always safe to revoke and reissue with a known good procedure. There's a point where this is pointless, and one where it's necessary, and I'm not going to pretend I know ahead of time or even afterwards necessarily. But that's why I think it's important to focus on what the CA believes. We can't reasonably hold CAs responsible for revoking certs they didn't know were mississued, unless they really should have. We can hold them responsible for recovocation they know needs to happen. And I don't think acquiring that knowledge is necessarily instant (although they do need to properly investigate). Asking the community doesn't change that equation.
