I would like to know whether an SSL certificate was revoked. The website no longer serves up that certificate, I only have the domain name and the serial number.
The SSL certificate was replaced 5 months before expiry without explanation. That doesn't sound normal to me as that's nearly 25% of the lifetime of the certificate "thrown away" early so I suspect it was revoked.
I would like to know how to check this, as I can only find methods that will check the status of a "live" certificate.
