openssl_csr_sign

Sign a CSR with another certificate (or itself) and generate a certificate (PHP 4 >= 4.2.0, PHP 5)
resource openssl_csr_sign ( mixed csr, mixed cacert, mixed priv_key, int days [, array configargs [, int serial]] )

Example 1670. openssl_csr_sign() example - signing a CSR (how to implement your own CA)

<?php
// Let's assume that this script is set to receive a CSR that has

// been pasted into a textarea from another page
$csrdata = $_POST["CSR"];

// We will sign the request using our own "certificate authority"

// certificate.  You can use any certificate to sign another, but

// the process is worthless unless the signing certificate is trusted

// by the software/users that will deal with the newly signed certificate


// We need our CA cert and its private key
$cacert = "file://path/to/ca.crt";
$privkey = array("file://path/to/ca.key", "your_ca_key_passphrase");

$userscert = openssl_csr_sign($csrdata, $cacert, $privkey, 365);

// Now display the generated certificate so that the user can

// copy and paste it into their local configuration (such as a file

// to hold the certificate for their SSL server)
openssl_x509_export($usercert, $certout);

echo $certout;

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

    echo $e . "\n";

}
?>

Code Examples / Notes » openssl_csr_sign

To generate a self-signed certificate, pass NULL as the signing certificate (2nd parameter). For example: $req_key = openssl_pkey_new(); $dn = array( "countryName" => "US", "stateOrProvinceName" => "Colorado", "organizationName" => "yPass.net", "organizationalUnitName" => "yPass.net", "commonName" => "yPass.net Root Certificate" ); $req_csr = openssl_csr_new($dn, $req_key); $req_cert = openssl_csr_sign($req_csr, NULL, $req_key, 365);

Here is an sample how to create valid X.509 Public and Private Key (cert/key). When not using self signed the 4.2.1 segault. You need the CVS code at least for openssl. <? Header("Content-Type: text/plain"); $CA_CERT = "CA.cert.pem"; $CA_KEY = "CA.key.pem"; $req_key = openssl_pkey_new(); if(openssl_pkey_export ($req_key, $out_key)) { $dn = array( "countryName" => "DE", "stateOrProvinceName" => "Frankfurt", "organizationName" => "smcc.net", "organizationalUnitName" => "E-Mail", "commonName" => "Testcert" ); $req_csr = openssl_csr_new ($dn, $req_key); $req_cert = openssl_csr_sign($req_csr, "file://$CA_CERT", "file://$CA_KEY", 365); if(openssl_x509_export ($req_cert, $out_cert)) { echo "$out_key\n"; echo "$out_cert\n"; } else echo "Failed Cert\n"; } else echo "FailedKey\n"; ?>
