Risposte:

Stai creando un certificato versione 1. Questi primi certificati non hanno estensioni, motivo per cui le estensioni nelle tue richieste non vengono copiate.

Per risolvere questo, è necessario aggiungere il x509_extensions = <name> opzione; dove <name> è il nome di una sezione che elenca le estensioni da aggiungere al nuovo certificato. Questo costringerà OpenSSL a creare certificati versione 3, che è la versione che supporta le estensioni. Se non si desidera forzare la CA ad aggiungere ulteriori estensioni ai nuovi certificati, lasciare semplicemente questa sezione vuota - ma deve esistere per creare un certificato V3.

Per esempio: 

x509_extensions = cert_ext

[cert_ext]

# This is an empty section - the next section starts below

Potrebbe essere più sicuro aggiungere il basicContstraints estensione ai tuoi nuovi certificati con il basicConstraints = critical,CA:FALSE opzione nella tua sezione, per garantire che nessuno cerchi di intrufolare una richiesta di certificato CA attraverso. 

x509_extensions = cert_ext

[cert_ext]

basicConstraints = critical,CA:FALSE

# The next section starts below

Per firmare la richiesta e generare il certificato del sito, utilizzo questo comando: ALTNAME="$ALTNAME" openssl x509 -req -in csr/$domain.csr -CA data/certs/rootCA.pem -CAkey data/private/rootCA.key -CAcreateserial -out data/certs/$domain.crt -days 500 -sha256. Non uso alcun file di configurazione per la firma, quindi non sono sicuro di come "forzare la versione 3"
— dangonfast
La tua risposta e Questo aiutato molto
— dangonfast
Potresti usare il openssl ca comando invece.
— garethTheRed
Sì, ma non ho configurazione per quello ...
— dangonfast
Il [CA_default] è la configurazione per questo :-)
