openssl_csr_new - Generates a CSR

SYNOPSIS

       mixed openssl_csr_new (array  $dn, resource  &$privkey, [array  $configargs], [array  $extraattribs])

DESCRIPTION

       openssl_csr_new(3) generates a new CSR (Certificate Signing Request) based on the information provided by $dn, which represents the Distin-
       guished Name to be used in the certificate.

       Note

	       You need to have a valid openssl.cnf installed for this function to operate correctly. See the notes under the installation section
	      for more information.

PARAMETERS

	      o $dn
		- The Distinguished Name to be used in the certificate.

	      o $privkey
		-$privkey  should  be  set  to	a private key that was previously generated by openssl_pkey_new(3) (or otherwise obtained from the
		other openssl_pkey family of functions). The corresponding public portion of the key will be used to sign the CSR.

	      o $configargs
		- By default, the information in your system openssl.conf is used to initialize the request; you can specify a configuration  file
		section  by  setting the config_section_section key of $configargs. You can also specify an alternative openssl configuration file
		by setting the value of the config key to the path of the file you want to use. The following  keys,  if  present  in  $configargs
		behave as their equivalents in the openssl.conf, as listed in the table below.

	      o $extraattribs
		-$extraattribs is used to specify additional configuration options for the CSR. Both $dn and $extraattribs are associative  arrays
		whose keys are converted to OIDs and applied to the relevant part of the request.

RETURN VALUES

	Returns the CSR.

EXAMPLES

       Example #1

	      Creating a self-signed-certificate

	      <?php
	      // Fill in data for the distinguished name to be used in the cert
	      // You must change the values of these keys to match your name and
	      // company, or more precisely, the name and company of the person/site
	      // that you are generating the certificate for.
	      // For SSL certificates, the commonName is usually the domain name of
	      // that will be using the certificate, but for S/MIME certificates,
	      // the commonName will be the name of the individual who will use the
	      // certificate.
	      $dn = array(
		  "countryName" => "UK",
		  "stateOrProvinceName" => "Somerset",
		  "localityName" => "Glastonbury",
		  "organizationName" => "The Brain Room Limited",
		  "organizationalUnitName" => "PHP Documentation Team",
		  "commonName" => "Wez Furlong",
		  "emailAddress" => "wez@example.com"
	      );

	      // Generate a new private (and public) key pair
	      $privkey = openssl_pkey_new();

	      // Generate a certificate signing request
	      $csr = openssl_csr_new($dn, $privkey);

	      // You will usually want to create a self-signed certificate at this
	      // point until your CA fulfills your request.
	      // This creates a self-signed cert that is valid for 365 days
	      $sscert = openssl_csr_sign($csr, null, $privkey, 365);

	      // Now you will want to preserve your private key, CSR and self-signed
	      // cert so that they can be installed into your web server, mail server
	      // or mail client (depending on the intended use of the certificate).
	      // This example shows how to get those things into variables, but you
	      // can also store them directly into files.
	      // Typically, you will send the CSR on to your CA who will then issue
	      // you with the "real" certificate.
	      openssl_csr_export($csr, $csrout) and var_dump($csrout);
	      openssl_x509_export($sscert, $certout) and var_dump($certout);
