How to proof/check if a certificate was revoked


#1

I issued several certificates using certonly, now I want to revoke the older one:

  1. how can I do/proof/check that?
  2. if I renew a certificate is the older one automatically revoked?
  3. Is there a certification revocation list in place?

#2

well there is no CRL but an OCSP.


here’s an example that is even using LE.


#3

No, renewals do not automatically revoke old certificates.


#4

You can upload the certificate to https://certificate.revocationcheck.com/ to check its revocation status. Note that you have to manually revoke the certificate using the client software. It won’t happen automatically.
