I want to get a list of ssl certificates used by all fqdn of a domain name. So, we can imagine that I search google.com certificates. I will get the google.com and www.google.com certificate but I want also get checkout.google.com certificate and others.
For this I can use this page which use certificate transparency : https://www.google.com/transparencyreport/https/ct/#domain=google.com&incl_exp=false&incl_sub=true
This page give a github repository : https://github.com/google/certificate-transparency
I cloned it and install all things to use Python dashboard. But I don't know how to query the database to find all google.com certificates ?
There is not public API available, not database filled...
Do you know a way to get all FQDN for a domain name by using certificate transparency ?
This is an old question but in case others run across stumbleupon this...
https://crt.sh exists now and you can query all the certificate domains they have observed. Also facebook has a email subscription service you can get notified for new certificates for specific domains. https://developers.facebook.com/tools/ct/.
