int
openssl_verify ( string data, string signature, mixed pub_key_id )
| 警告 |
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随
PHP 以后的发布而改变。使用本函数风险自担。 |
Returns 1 if the signature is correct, 0 if it is incorrect, and
-1 on error.
openssl_verify() verifies that the
signature is correct for the specified
data using the public key associated with
pub_key_id. This must be the public key
corresponding to the private key used for signing.
例子 1. openssl_verify() example |
<?php
$fp = fopen("/src/openssl-0.9.6/demos/sign/cert.pem", "r");
$cert = fread($fp, 8192);
fclose($fp);
$pubkeyid = openssl_get_publickey($cert);
$ok = openssl_verify($data, $signature, $pubkeyid);
if ($ok == 1) {
echo "good";
} elseif ($ok == 0) {
echo "bad";
} else {
echo "ugly, error checking signature";
}
openssl_free_key($pubkeyid);
