Example 1669. 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);
openssl_pkey_export($privkey, $pkeyout, "mypassword") and var_dump($pkeyout);

// Show any errors that occurred here
while (($e = openssl_error_string()) !== false) {

    echo $e . "\n";

}
?>
