  <pre><code>Country Name (2 letter code) [US]:
  Organization Name (eg, company) [My Company Name LTD.]:
  Common Name (eg, YOUR name) [something]:
  </code></pre>
  
  <p>While creating certificates with </p>
  
  <pre><code>openssl req -config openssl.cnf -new -x509 ...
  </code></pre>
  
  <p>given the fact those parameters are provided in the <code>openssl.cnf</code> file</p>
  
  <p>e.g.</p>
  
  <pre><code>countryName         = Country Name (2 letter code)
  countryName_default     = US
  countryName_min     = 2
  countryName_max     = 2
  0.organizationName      = Organization Name (eg, company)
  0.organizationName_default  = My Company Name LTD.
  commonName          = Common Name (eg, YOUR name)
  commonName_max      = 64
  commonName_default      = ${ENV::CN}
  </code></pre>
