Where is Let’s Encrypt Authority X3 intermediate certificate by ISRG Root X1?

I can’t find the intermediate certificate of Let’s Encrypt Authority X3 signed by Signed by ISRG Root X1 on https://letsencrypt.org/certificates/ . Can someone please tell me where to find it?

Otherwise, is there any way to force the client to get the certificate that signed by Let’s Encrypt Authority X1 ?

Maybe I’m not understanding something. Isn’t it on the page you link, right near the top ( the first two lines below the Intermediate Certificates title) …

Let’s Encrypt Authority X3 (IdenTrust cross-signed): [txt] [pem] [der]
Let’s Encrypt Authority X4 (IdenTrust cross-signed): [txt] [pem] [der]

Serverco, that’s the IdenTrust cross-signed cert. The Op is looking for the ISRG cert.

Jsha recently said those certs will probably be produced during the next key signing ceremony, somewhere in May if I recall correctly.

Thanks - I knew I must be missing something :slight_smile:

Thank you for the information. That’s exactly what I need!

Hello @ukyang,

I think @osiris talks about this jsha comment. But the ETA for ECDSA intermediate certs is before August 1.
