Where can I find OCSP responder certificate?

Hi all,

Where can I find OCSP responder certificate for Let’s Encrypt X1 CA?

Generally OCSP responder certificate is concluded in a OCSP response however it can’t be found in a response from ocsp.int-x1.letsencrypt.org.
When lacking OCSP responder certificate OCSP response can’t be verified properly.

It can’t also be found in the repository which provides root or intermediate certificates.

Any help?



@rmhrisk have let me know that all OCSP reponses are issued by X1 intermediate CA directly and can be verifyed by X1 intermediate CA certificate.

I’ve confirmed that the response can be verified by the X1 CA certificate.

I’ll close this ticket.
