openssl_signGenerate signature

Description

bool openssl_sign ( string $data , string &$signature , mixed $priv_key_id [, int $signature_alg= OPENSSL_ALGO_SHA1 ] )

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.

Parameters

data

signature

If the call was successful the signature is returned in signature .

priv_key_id

signature_alg

Defaults to OPENSSL_ALGO_SHA1. For more information see the list of Signature Algorithms.

Return Values

Returns TRUE on success or FALSE on failure.

Changelog

Version Description
5.0.0 The signature_alg parameter was added.

Examples

Example #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");
$priv_key fread($fp8192);
fclose($fp);
$pkeyid openssl_get_privatekey($priv_key);

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

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