What is sct files about nginx-ct HOT 4 CLOSED

Short question: Do you use Let‘s Encrypt?

Because Let‘s Encrypt is currently submitting the signed certificate to the logs and give you a certificate with the act embedded. So you might not need this module if your current certs have the sct‘s embedded. If you do not know how to do this let me know :)

You can verify it by the issue date. If it is after 29 March it should have it; if not you can renew it if you want it. Do you want to deploy expect-ct or what is your intention behind it?

Hi @Knight1

Thanks for the reply and for the observation.

Yes, I do use Let's Encrypt with certbot.

I did use this website https://cryptoreport.websecurity.symantec.com/checker/ to verify my CT and it tells me

• Certificate Transparency: Not embedded in certificate

But how can I check if my certificate already have the sct's embedded?

Should I just renew it?

I understand.

Well, currently my webapp product is running in a lot of customers that are instructed to use Chrome for better experience and I do not want them to face any kind of "insecure website" or something.

I just knew about this CT a few days ago and I'm trying make everything works fine. But I think on the next renewall that's should be fine.

Thanks a lot for your help and attention. Much appreciated.
