However, I am not sure if this applies to the variables you mention. Improve this answer. Sign up or log in Sign up using Google. Sign up using Facebook. These simply define the way that the name and certificate information are displayed to you for "confirmation" before signing a certificate and should be left as-is. The default digest algorithm - this can be left alone unless you know what you're doing - and whether or not to preserve the DN.

Preserving the DN is a site-specific thing: if you want all your certs to have the same DN order, than so "no" here and openssl will re-order the attributes in the DNs of CSRs to make them consistent.

However, if you want to let people determind the order of their DN, set this to "yes. All fields listed as "supplied" must be present. All fields listed as "optional" are allowed, but not required to be there. Anything allowed must be listed! So this policy requires the same country, State, and Organization name as the CA for all certs it signs. Here we define the section for the req command. We define the default size, the name of the keyfile, the section that defines how to form the DN, what attributes to put in the request, and the section that defines what x extensions to request.

This defines what kind of strings to accept. See the man page for details. So, this time, we just add the information as part of the command line arguments and OpenSSL puts that information into the certificate. So, as we can see, all the details are filled out for us by OpenSSL. If, for example, we did not want to add Organizational Unit Name, we could just omit OU from the list. Again, we would have to do the same when we request the certificate for the Certificate Authority.

Though we could copy, modify the parts that we want, and then past it back in. However, this is also a little bit cumbersome. We could take this one step further and add all the data into a configuration file.

We can generate a configuration file to hold some of the information we supplied on the command line. The information in this configuration file captures just a subset of the available configurations and parameters, but it solves the current issue.

If we step through it, the first part : [ req ] describes default properties used to generate keys and certificates. It tells OpenSSL not to encrypt the keypair.
