openssl_pkcs7_encrypt

Encrypt an S/MIME message

bool **openssl_pkcs7_encrypt** string $input_filename string $output_filename  $certificate  $headers int $flags int $cipher_algo

takes the contents of the

file named and encrypts them using an RC2 40-bit cipher so that they can only be read by the intended recipients specified by . openssl_pkcs7_encrypt``input_filename``certificate

input_filename

output_filename

certificateEither a lone X.509 certificate, or an array of X.509 certificates.

headers is an array of headers that will be prepended to the data after it has been encrypted. headers

    can be either an associative array
   keyed by header name, or an indexed array, where each element contains
   a single header line.
  `headers`

flags can be used to specify options that affect the encoding process - see . flagsPKCS7 constants

cipher_algo One of . cipher constants

Voorbeeld: example

<?php
// the message you want to encrypt and send to your secret agent
// in the field, known as nighthawk.  You have his certificate
// in the file nighthawk.pem
$data = <<<EOD
Nighthawk,

Top secret, for your eyes only!

The enemy is closing in! Meet me at the cafe at 8.30am
to collect your forged passport!

HQ
EOD;

// load key
$key = file_get_contents("nighthawk.pem");

// save message to file
$fp = fopen("msg.txt", "w");
fwrite($fp, $data);
fclose($fp);

// encrypt it
if (openssl_pkcs7_encrypt("msg.txt", "enc.txt", $key,
    array("To" => "nighthawk@example.com", // keyed syntax
          "From: HQ <hq@example.com>", // indexed syntax
          "Subject" => "Eyes only"))) {
    // message encrypted - send it!
    exec(ini_get("sendmail_path") . " < enc.txt");
}
