Such a CRL would need to be signed with the same key as the certificate, so that if the key is compromised, a new, clean, crl can be created and considered valid from the same compromised key. To create a CRL with openssl you are supposed to use its CA functions, as described here .

It does the check for you, but also provides the OpenSSL command with the certificate and CA chain download for you to run locally if you prefer. Reply ↓ Jaime Hablutzel November 11, 2019 at 8:57 pm Certificate revocation list (CRL) CRLs are also signed with the CA key, but they only dictate information regarding end-user certificates. Usually, a 30 day span is given between new CRL submissions. Configuring.

Oct 09, 2013 · For each domain you create using my shell script, there is a ca.crt file that is created under the certificates directory. This ca.crt is a public key and can be freely distributed and installed within your company. Additionally there is a certificate revocation list titled ca.crl.

Previously on Building an OpenSSL CA, we created a certificate revocation list, OCSP certificate, and updated our OpenSSL configuration file to include revokation URI data. Now we are ready to create our first server certificate and sign them with our fully armed and operational CA. Such a CRL would need to be signed with the same key as the certificate, so that if the key is compromised, a new, clean, crl can be created and considered valid from the same compromised key.

I'm sure something is wrong with my command or the configuration but reading the documentation carefully and playing around with the configuration did not help.
