openssl_sign() computes a signature for the specified data by using SHA1 for hashing followed by encryption using the private key associated with priv_key_id. Note that the data itself is not encrypted.

Пример 1. openssl_sign() example

<?php
// $data is assumed to contain the data to be signed

// fetch private key from file and ready it
$fp = fopen("/src/openssl-0.9.6/demos/sign/key.pem", "r");
$priv_key = fread($fp, 8192);
fclose($fp);
$pkeyid = openssl_get_privatekey($priv_key);

// compute signature
openssl_sign($data, $signature, $pkeyid);

// free the key from memory
openssl_free_key($pkeyid);
?>
