Re: ./CA.pl -newreq specify servername

[Paul Nelson <nelson@xxxxxxxxxxx>]

For OpenSSL 1.0.2:

Are you asking how to get a DNS Subject Alternative Name extension into the certificate?

You would need to edit an openssl.cnf file and add the proper stuff to get this extension. Check the man page for x509v3_config.

The item you want to put in the config file is subjectAltName=DNS:myserver.mydom.com

Also see the man page for ca and config

You may need to run the openssl ca command directly instead of using CA.pl so you can use the -extensions argument.

 #./CA.pl -newreq --> is there a way to specify server name? For example gitlabinternal.  By default, it saves in file newcert.pem

 #./CA.pl -sign 

I ran the below command to copy 

#cp newcert.pem gitlabinternal.pem 

#openssl x509 -in gitlabinternal.pem -noout -text

Is there a way to specify servername in ./CA.pl -newreq  command ? Please suggest further. Thanks in advance.
