title: Sign certificate without prompt in shell-script
body: <p>I'm writing a shell-script to sign certificates using openssl:</p>
  
  <pre><code>openssl ca -config "$CONF" -out "$BOXCERT" -infiles "$CSRFILE"
  </code></pre>
  
  <p>However, when running it, openssl always asks whether I want to sign the certificate:</p>
  
  <pre><code>Certificate is to be certified until Mar 19 11:50:33 2023 GMT (3653 days)
  Sign the certificate? [y/n]:y
  
  1 out of 1 certificate requests certified, commit? [y/n]y
  Write out database with 1 new entries
  Data Base Updated
  </code></pre>
  
  <p>I would like the script to run non-interactively in a server. Is there some command-line parameter or configuration file option to tell OpenSSL to sign the certificate and commit it without prompting?</p>
