Avoid duplicate alerts for same certificates or renewals

[oskar456]

To avoid unnecessary noise, it would be nice if there were options:

• not to report a certificate that has been already reported in some different log
• not to report a certificate sharing public key with an already reported certificate (targeted mostly for renewals without rekeying)

Thanks for this great peace of software!

Cert Spotter already suppresses notifications for duplicate certificates, as long as you don't specify the -no_save option.

The second suggestion is a good one.

One caveat: Cert Spotter considers the pre-certificate and final certificate to be different, so you may get up to two alerts for a single issuance. It would be good to deduplicate those alerts too.

Is Cert Spotter already suppresses notifications for duplicate certificates, as long as you don't specify the -no_save option. documented anywhere? Because I ran in to this and didn't find any docu. Maybe it is just hidden well.

@certrik what information would have been helpful? That turning on -no_save causes duplicate notifications to be sent?

[certrik]

Yes. That is an interesting information.
