X.509 allows for a self-signed certificate dedicated to CRL signing (with the same name, of course). But that's not acceptable for RFC5280.

You can generate a self-issued certificate dedicated to CRL signing (same name, different key, signed by your root). That's acceptable for RFC5280, but you'll have to check with your clients. And find a way to distribute this certificate.

Hi List,

I would like to setup an OpenSSL-based offline Root CA.

Certificates issued by this Root CA contain a CDP.

I would like to issue CRLs every 3 days, which would mean that I would have to take the offline Root CA online each 3 days.

Is there a way to let the Root CA issue a "CRL signer certificate", which can then run on a different machine for CRL signature?

For OCSP it seems to be possbile (RFC2560, 2.6 - "OCSP Signature Authority Delegation"). Does anybody know whether it's possible for CRL's using OpenSSL?

Thanks for any advice,
Sven
