EXPERIMENTAL. The behaviour of this function, the
name of this function, and anything else documented about this
function may change without notice in a future release of PHP.
Use this function at your own risk. |
Returns TRUE on success or FALSE on failure.
If successful the signature is returned in
signature.
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.
Example 1. openssl_sign() example |
<?php
$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);
openssl_sign($data, $signature, $pkeyid);
openssl_free_key($pkeyid);
?>
