openssl_csr_sign

(PHP 4 >= 4.2.0, PHP 5)

openssl_csr_signSign a CSR with another certificate (or itself) and generate a certificate

Descrierea

resource openssl_csr_sign ( mixed $csr , mixed $cacert , mixed $priv_key , int $days [, array $configargs [, int $serial = 0 ]] )

openssl_csr_sign() generates an x509 certificate resource from the given CSR.

Notă: Trebuie să aveți un fișier openssl.cnf valid instalat pentru ca această funcție să opereze corect. Vedeți notele în secțiunea de instalare pentru informații suplimentare.

Parametri

csr

A CSR previously generated by openssl_csr_new(). It can also be the path to a PEM encoded CSR when specified as file://path/to/csr or an exported string generated by openssl_csr_export().

cacert

The generated certificate will be signed by cacert. If cacert is NULL, the generated certificate will be a self-signed certificate.

priv_key

priv_key is the private key that corresponds to cacert.

days

days specifies the length of time for which the generated certificate will be valid, in days.

configargs

You can finetune the CSR signing by configargs. See openssl_csr_new() for more information about configargs.

serial

An optional the serial number of issued certificate. If not specified it will default to 0.

Valorile întoarse

Returns an x509 certificate resource on success, FALSE on failure.

Exemple

Example #1 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");

$usercert openssl_csr_sign($csrdata$cacert$privkey365);

// 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";
}
?>
